I searched and searched and searched endlessly to build a spreadsheet of what to buy before ever taking on this journey from the car to what I wanted in the drivetrain for approximately 2.5 years. Searching craigslist/copart/ebay endlessly until I ran across a deal in my budget for a $2k running driving Z car. This led me to Virginia and I bought this daily driver 1976 280Z with 168k miles and in fairly good shape. My uncle and I drove it home 300+ miles with dry rotted 10 year old tires and 40 year old bushings with a slight hint of white smoke under hard acceleration on the interstate! Then the build began"¦ This was in March of 2012 just after grabbing my BS in Civil Engineering from UT Knoxville in Dec of 2011. I didn't start buying until December of 2012 and I haven't stopped since haha[/font][/size] -First I had to figure out the dreaded fluid in the passenger floorboard...leaky heater control valve so I wound up using a Bronco heater valve 74628 (Advance Auto Parts), 2-90* hoses, spare pieces of 5/8" hose and some hose clamps to fix that right up. PITA to get to with stock heater core/ac junk in the way BTW. Future plans are JCI/Vintage Air! -Engine spec'd out to be cheaper for an LS1 pullout if I could find the right deal but after considering the fuel mileage gains and ease of finding another engine for less if it went south I went 5.3 all the way. Plus boost always sounds better for the future! I have a spreadsheet list for that too! -2002 5.3 from a Chevy Avalanche with 80k that ran good (or at least that's what the guy at the junkyard said!) -Drive by cable was my goal from the start to get a better "feel" for the car so I bought a new throttle body and used ls1 intake, fuel rails, oil pan/pickup tube, etc... But I kept the truck spacing on the accessories (cheaper). -Transmission, besides the car, this was the worst to find and ultimately I went with the TR6060 over the T56. -2011 Camaro SS TR6060 with 2k miles ($1600 with free head stud kit valued around $225) -TR6060 has more stock holding power than a T56, a trans cooling system, and supposedly shifts smoother -But the downsides are that it is more rare (1st in a LS-Z), fixed yoke rear, taller gears, & uses a remote shifter From then on out I used the "Documemtation" of how to swap an LS1 T56 combo into a Z car and along side other builds on HybridZ to get to where I'm at. From Cooling to the RT Diff Mount to the Fuel Cell Setup I've researched and stalked tons of pages to get where I'm at and asked a handful of questions. My hats off to the site and all who put their 2 cents in because it would've been harder without it for sure. If I can help anybody else that has questions just shoot me a message about the swap. HybridZ and LS1Tech are your best friends during this swap so use them! The 5.3 had no real issues as in tapping the alternator hole (I was scared to do this at first) or cutoff the protruding section from the side of the block but it cuts like butter with a saw. 11/32" Drill Bit & 10mm x 1.5 Tap. I did mine inside the car, so out or in it doesn't matter. My goal is to daily drive it to work to keep miles off my truck and to replace my burning passion for buying a new Vette since I bought a new '12 Duramax instead. So power upgrades are essential to fulfill my daily need for speed. Future dream plans are a turbo, beefed up rear, and A/C. But I'm not sure if they can all be satisfied together so we'll see or I may just go and build another with a 5.3/auto/turbo drag setup and leave the stick with a/c for autox/daily driving.

The engine will try to run properly but won't let itself until this is done even though the crankshaft is mechanical. Other than that the engine ran flawlessly from ChevyThunder's harness. This procedure is popping up only if the computer and engine did not match from the factory and I did not get the CPU with the engine. Next time I will. -Do NOT cut anything off of the Datsun harness until the project is fully running and it all works, ask me how I know... I had to fight a couple of electrical gremlins that were working just fine before I took out the motor and they didn't once I was ready to drive"¦like brake lights and interior everything electrical, but the headlights, blinkers, stand alone engine and the gauges worked flawlessly. -I'd go 2-5/8" on the triple gauges. Mine look too small personally but they're fine and it's too late now -80 or 100 Micron Filter before the Walbro is mandatory but my 30 Micron did fine but supposedly too restrictive. -Upgrade the suspension/bushings like I did and redo all supporting components while they're easy to get to. -My clutch is actually for an LS1 T56 setup but works with what I have so there's my 2 cents"¦buy the trans first not the parts that go in it. They were having a new years sale and I just knew I'd be putting in a T56"¦ Push button momentary switch wired for the reverse lockout solenoid because my harness was made for a T56 and I am using a GPS speedo not the VSS. 3 amp fuse and a switch from RadioShack and it works good. Keeps me from going into reverse on a 6-5 downshift. It does literally take two hands to jam it in reverse without the solenoid activated and that will not mess it up because it's only a spring pushing back. More TR6060 downsides I'm coming aware of now that it's driveable, theres a slight clanging inside the trans when you let out of the clutch while it's in neutral. Apparently all 5th Gen Camaros have this from what I read even brand new ones with no miles on them (not just GM TR6060's either). It's a factory sound and slight vibration in the shifter (get a loud exhaust or a good stereo!). Another issue with buying a TR6060 are the batch of factory defective transmissions, which are serial numbers 0-25000 which have a weak main shaft that's not heat treated like the new ones and an issue about not having an output shaft bearing installed. This has been well known to modified 2010's and some 2011 cars that are manual that have broken with superchargers installed and even bone stock 436hp levels. I was unlucky and my serial is 24302... So since I'm going to only have low 300's for horsepower right now I'll be fine but in the future a main shaft upgrade will be necessary. Main shaft (stock) is good for up to 475hp from what I've read. Gearing is another aspect in transmissions that I was curious about as well... LS1 T56 - 2.66 , 1.78 , 1.3 , 1.0 , 0.74 , 0.50 (not GTO ratios) TR6060 - 3.01 , 2.07 , 1.43 , 1.0 , 0.84 , 0.57 Grand total costing me around $14k including the car. That includes a few screw ups, new GM 10.9 bolts everywhere, high end fluids/gaskets, and quality parts to make sure they will not fail during daily use. Most all the parts I bought were brand new unless it wasn't critical like the used headers. It took me approximately 1 year to do it all but could've been done in half the time if I dedicated more time to it. If I can figure out the picture situation I'll load some on here but until then all my pics are on Flickr via my signature below. Thanks Travis

I have an old school JTR conversion i started ~15 years ago. (No LS's motor's back then!) After i put 1,000 miles on the car i transferred to Australia. You can see that effort here: http://aka.ms/chuckscar In the process of driving it to the storage facility the fuel line was pushed off the regulator spraying fuel on the headers and -well you get the idea instead of a Datsun going into storage i have a burn victim. Fast forward to today with a couple of mice playing house in the rear quarter panels for the last decade+ resulting in some slow cancer I am trying to figure out what to do w/ the car. So far i have changed the carb from the Edelbrock to a brand new Summit Racing/Holley 750cfm vacuum secondary carb, ran a fuel line to to plastic bottle w/ a hand pump, pulled the plugs gave it a shot of Oil in the cylinders, turned it over for a minute without the coil, put the spark plugs back in and started it -YEAH! At this point the plan is to strip it down, fix the rust, reshoot it and make it into a sunny day toy. My question is should i start a single build thread or post as i progress? Thanks Chuck

My search for a good car ended up being pretty quick. I wanted a car that had a flawless interior, very little rust, but really did not worry too much about the condition of the engine or transmission because those are being upgraded soon. I lucked out and found a decent candidate, it was recently restored by an old navy guy but he wanted to let it go so he could fund a new corvette. It had very little rust, from what i could tell, the interior was in acceptable shape and the best part, It Ran! The only noticeable things wrong with it were some major dents in the frame rails from clueless mechanics jacking the car up over the last 30 years and a dull grinding noise when letting the clutch out which i am assuming is just the pilot bearing. I drove up to meet him the weekend after seeing the posting and ended up buying the car, this was late June of 2016, I was able to drive it the 250 miles home that day... kind of. My phone does not hold its battery very well and i was depending on the GPS to get me home, before i even made it to my state line, my phone died. This ordinarily would not have been a problem, but neither of the plugs in the car would work. I ended up stopping at a gas station to get a paper map and traveled like a caveman the rest of the way home. Then, the second i hit my county line, the clutch pedal just dropped to the floor and would not un-engage. I wrestled it into neutral and rolled into the nearest gas station. When i popped the hood i noticed the clutch reservoir was bone dry. Luckily they had some dot-3 for me to fill it back up and it lasted until i made it home. I would find the source of the issue later.

Howdy All - just came into a nice 1972 240Z that currently has a Chevy 350 in it. Conversion already done, but I'd like to drop a few more HP into it. I have two questions - 1) I'm thinking a 383 with 450-500 hp would be a nice match. Since it is already setup for Chevy, i'll stay that route. What are some of the other options I should consider that are popular? 2) Engine source. There are a TON of engine builders on the internet. I know that many of them use junk Chinese parts and it will probably grenade quickly. Are there any reputable chevy engine builders that folks on the forum have had good luck with? Thanks for the help!!

Hi guys, here's where I'm at- I'm trying to get underway on a v8 swap into my '73 240z. Car will be for street use/getting into trouble- nothing serious like autoX/track/drag. My plans are as follows: Chevy 350 engine 650cfm vac secondary carb MSD 6al ign Camaro t5 trans Custom driveshaft JTR engine/trans mounting kit JTR headers (maybe) Custom exhaust Upgraded fuel pump OEM radiator from v8 car I have been doing a ton of reading and already ordered the JTR manual but still have a few logistical questions. I found a good candidate for a motor, BUT it is a truck vortec motor. I've read there are 2 main types of flywheels- 153 & 168 tooth. Don't know which one this engine has. Since I plan on using a camaro T5 (I know these get a bad rap, but I think for a mostly stock 350 I should be ok if I don't abuse it?) I'm not sure about fitment. So, first question, 1) what kind of fitment issues should i be thinking about? As long as the flywheel is the right diameter it should just bolt up? My z is carb'd and this engine ill be too. So, second question, 2) Do you think my fuel system can flow enough for a 350? It has a return line so I'm assuming the pump isn't close to max capacity right now, which is why i wasn't sure if an upgrade would be necessary since i'm staying carb'd. I have a couple more, but lets start with these and hopefully reading the manual should answer most of them. Mostly stumped on the t5 trans fitment to what other engines. I've been reading a lot on hot rod forums but haven't exactly found an answer. Thanks, Adrian

Hi guys. I just picked up a rebuilt 1997 mark vi vortec 454 .030. The engine was done to stock specs. The guy I got it from started a project and abandoned it so I got the complete long block for a great price. Everything was rebuilt/replaced on the engine. These run about 9:1 stock compression and I'm assuming that it's going to be right around there give or take .3. I have a question. I'm going to be upgrading the cam before I get further into the project. What is the largest cam that the vortec heads can handle without machining the valve guides for seal to retainer clearance? I don't feel like taking the heads off and totally disassembling them. I need a quick cam change. I will upgrade the valve springs if necessary. I'd also prefer to stay with the nonadjustable valvetrain vs. spending more money. It's already going to cost an additional $1200 or so in parts for me to get this to work. Engine will be a carb engine with an edelbrock performer RPM intake. Hei distributor. Vehicle it's going in is my truck. 1992 Chevy k3500 mason dump 4x4, nv4500 5 speed with 4.56's front and rear. Truck is heavy but I need this engine to have some power. I don't tow, but do get loads stone (6000lbs on average) and the 350 that was in it required downshifts on hills even unloaded. I'd like this to pull above 5k and not die out like the TBI 350 did at 3800. Truck weighs 7540 with me in it. Any advice? Thanks.

Hello, I have a question for anyone who is running the stock or stock like aluminum 3 core radiators with their SBC's. What radiator hoses are you using? I bought two of the "universal" hoses from o'reilly's and my total was over $50. Just wondering if anyone could pull the numbers of their hose so I can see if I can find a cheaper option. I haven't put the engine in the car yet, so there is still time to return the hoses if other options are available. Thanks, Han -

First off, i'd like to say hey to everyone, as i'm new here and this is my first post. I'm not sure if there's an introduction section, i hope i didnt miss it. Onto business: I've loved z's ever since i was a tiny kid and didn't know the first thing about them. Now, after learning more and more about them, I want my own. Here's the rundown: I want a 280z, maybe year doesn't matter too much to me. I want to drop in a chevy, I found an ls3 I like. I realize this thing is gonna be fast but i dont want something thats only enjoyable on the track. Although I want to do this right and not cut any corners, i dont want to spend an ungodly amount of money on this as it really is just a toy. I'm not new when it comes to street cars, i've driven plenty, but ive never owned anything personally other than yukons, dodge 1500's, and wranglers. So having said that, i dont know a whole lot when it comes to mods like this. Here are my questions: -How does this engine seem? http://paceperformance.com/i-7739382-19259233-special-ls3-525hp-with-free-shipping.html a bit pricey i know but i like nice things and horses -The only axles i'm familiar with are the ones for my wrangler, so fill me in on what you'd recommend for 400-500 hp -I understand the t56 is a preferable transmission for this kind of build, does someone mind to elaborate? -what rear tire sizes are you guys fond of? what brands/models? -I've heard of some people running mustang brakes or toyota brakes, what do you guys have/recommend? -Although i eventually plan on adding a completely new suspension, painting it, other "pretty stuff", etc, what are things that you guys see as "essential" for an ls swap? I'm not trying to break anything or die cause i know ill be giving this thing some hell. Lastly, do you guys know of any places that do good work on z's? I'm in the nashville area of tennessee. I want them mainly to do the heavier stuff like axle and engine swapping. Thank you all in advance, can;t wait to get some answers.
