Guest speedsun Posted January 21, 2007 Share Posted January 21, 2007 i've been checking out this cool site for a few days now. im am currently looking for a 280z, i will be checking on one tomorrow and i am hell bent on doing a sbc swap into it. i dont really want to fool with alot of wiring and fuel injection, just the classic v8 with mild mods. what suggestions do you have on a powerplant for this z and differential too. even if you just link me to some great threads it would be greatly appreciated. btw im new to this site but not new to the nissan family i've owned: 2 maximas, 1 altima, 2 240sx's, and i currently drive a 04 sentra for point a to b Quote Link to comment Share on other sites More sharing options...
Mikelly Posted January 21, 2007 Share Posted January 21, 2007 How about you link you to some threads via our search engine? There are a lot of threads on this very discussion, and we typically don't spoonfeed noobs... Your average SBC consists of an average 350 with a T5 or T56 tranny. You can get by with the stock R200 diff until you decide to upgrade to CV axles and LSD... Welcome aboard and prepare to read a lot...

jnjdragracing Posted January 22, 2007 Share Posted January 22, 2007 Welcome aboard, Where in NC to you stay? Good luck with your search for a Z and I think a 350chevy is a good way to go. John Quote Link to comment Share on other sites More sharing options...

simplybebop Posted January 22, 2007 Share Posted January 22, 2007 me and speedsun both are considering doing this swap, i think a chevy 302 would be a good choice with maybe t56 if i can get my hands on one cheap, nice site btw, this is my first post but i have been reading alot lately.

buZy Posted January 22, 2007 Share Posted January 22, 2007 If you are thinking of a T56 here is a great dependable conversion kit from Bob Weir. http://www.weirhotrodproducts.com/ EDIT: Be warned, with all due respect Bob knows his product very well. Quality stuff and knowledge. Though be prepared to drop some jing for it. A good used t56 goes for around 1000 to 1200. His kit cost around 1300 with the clutch alum flywheel etc. With a driveshaft and few other details 3000 is very possible. If money is an issue for you too the TH350 is much cheaper and easier to get the car running. I don't want to sound like I am down playing autos at all here. They have definate advantages over a manual gear box. It all depends what you are going for... Keep searching and good luck. Brian Quote Link to comment Share on other sites More sharing options...

I'd go for the 350CI and gain the extra HP and torque... No matter how "cheap" you can get it, you'll wish you had done the 350 in the long run.

simplybebop Posted January 22, 2007 Share Posted January 22, 2007 ha read up on 302ci, heres a couple quotes from wikipedia and other sources Ray Goodman was down from Boerne, Texas near San Antonio doing some testing getting ready for the new season in his A/EA Under Cover Chassis Comp. Eliminator Car running a 302CI SBC with 1 Carb. on Racing Fuel putting out 770 HP. He ran a lifting 7.579 E.T. at 172.92 MPH. to take home $150.00 for the Quickest 1/4 Mile Open Wheel Car. 302 Chevrolet produced a special 302 in³ (4.9 L) engine for Trans Am racing. It was the product of placing the 3-inch stroke crankshaft from a 283 into a 4-inch bore 327 block. This engine was only used in the first-generation Camaro Z28. Conservatively rated at 290 hp (216 kW), actual output was around 360 hp (for the standard 4-barrel carb) to 400 hp (with optional dual 4-barrel carbs and other performance parts checked off on the option list). This block is one of 3 displacements that underwent a transformation for the 1968/1969 period when the main bearing size was increased from 2.30 in to 2.45 in. and it doesnt mention that large main size and good rod/stroke ratio have the dz coded blocks a 7500 rpm redline, with a unbalanced bottem end, balanced its good for around 9k the problem after that is outflowing your breathing equipment Quote Link to comment Share on other sites More sharing options...

Back in the day, I bought a '69 Z28 new (ask me how much I regret selling that beauty) and despite the alleged 360 HP, it was something of a dog around town. Admittedly, it had a close ratio Muncie (2.2:1 first gear!) but even with a 3.73:1 axle, it needed brutality in the launch (high revs/sidestep clutch pedal) to break the tires loose.

buZy Posted January 22, 2007 Share Posted January 22, 2007 I agree. There is no replacement for displacement. Quote Link to comment Share on other sites More sharing options...

In stock form they had little torque so unless you launched at high RPM and then it would just burn off those polyglas 70 series tires. In 1970 I had a 390 cu. in AMX and would look for Z28s to blow their doors off in a drag race. Get them on the highway where their high revving engine could work it was another story. BTW everyone I knew that had a '68 or '69 stock Z28 eventually blew the bottom end trying to constantly pull the advertised redline. Quote Link to comment Share on other sites More sharing options...
simplybebop Posted January 22, 2007 Share Posted January 22, 2007 its true its all about personal preference and yes alot of the JZ coded blockes had bottem end troubles, thats just because chevy didnt tell the owners of the jz coded blockes that they couldnt rev as high as the dz coded blocks. And yes they did have lack of tq and low rpms but that can be fixed with cam and heads. I have seen 302dz engines rev all the way to 9k+ with a tq curve as flat as the floor im sitting on, its all how u build them really. And the engine options for mine yet arnt nailed down thats just a possiblity i might be gunning for. I have also thought about a 335 with forged pistons and a good spray job. Money isnt a object at this point im just researching my options. In fact in off to check on a 280 so ill see you guys later. and my goals for this car will mainly be a highway racecar " as unsafe as that is" but i wanna be able to run solid in the 1320 but kill cobras from a 60 roll.

Mikelly Posted January 22, 2007 Share Posted January 22, 2007 ...And again, Why not go with a 350? Parts are practically falling from the trees and more power is available with less effort... If it's to do something different, then know that everyone who looks at it will assume it's a 350 anyway and you'll get to spend more money for the same power. Your approach is lacking a bit of logic here... Mike Quote Link to comment Share on other sites More sharing options...
Twoeightnine Posted January 22, 2007 Share Posted January 22, 2007 Yep "drop a tree fitty in er"! Mike has this one. Unless one is truly looking for a challenge just for the sake of "because it's there". Go with tried and true. It will go like hell and start every day. Opps....I just tripped over another 350 that fell out of that darned ol tree! You know, the fitty tree. Once they fall off of the fitty tree, they are called tree fitties.
