the Vortec heads come from the factory with a 5 angle valve job; just leave them alone and you'll be better off. Instead of spending the money on a 3 angle valve job get the heads ported.

Well I changed mu mid and bough a much more conservative motor today. My guess is that the motor will make between 285 to 300hp at the crank. The specs are as follows: fresh rebuilt 350 - Its a 4 bolt 010 70's block Block was decked and smoothin for faster oil flow Block has been powered hoaned from 030 to 040 Stock 883 heads New flattop 4rv pistons - 9.5:1 compression Rods and cranked turned new comp cam 268H and lifter Kit : http://www.summitracing.com/parts/CCA-CL12-210-2 edelbrock airgap intake new cam, rod and main bearing New feeeze plugs Motor came with a HEI distributer, water pump, and starter. PRICE : $700

Well after i priced out all the stuff to build my SBC i found this one for sale and think it might be a good fit for me. Just want to know if its a good buy? and what kind of power output i can expect out of it? Will it is a good street motor? Below is all the information the owner has provided me with so far: 355 SBC TRW .100 dome forged pistons 11.1:1 compression GM steel crank 5.7" rods with ARP rod bolts, Crane .630" solid roller cam Crane Gold rockers Edelbrock aluminum Victor Jr. heads 2.08/1.60 valves 64cc chambers 215cc runners, ARP head studs Edelbrock Victor Jr. intake Holley 750 double pumper SFI balancer 4 bolt main block bored .030 over. Block was line honed as well. The owner claim that it will make 485-500hp on 91 oct pump gas.

ok so i made an excel sheet to see how much it would cost to build a sbc 350 that would give me 300hp and the wheels and i'm shocked at the price. I was heading into this think it was going to be a budget build. This so called budget build is gonna cost me a fortune. I wrote down all the numbers and it looks like its going to be way more expensive than i had expected. The expected cost is price of parts off ebay and other internet sites and the actual cost is what i have bought so far.

from what i have been reading online over the last few hours; i dont this the dome pistons will work with my vortec heads. I think the best i can hope for is flat tops with 2 VR's. below is a picture of my current pistons. Since i pulled my motor from 1994 chevy shortwide i looked up the spec for the 5.7L 350 that came with the 94 truck found that it had a compression 8.75:1 and was rated for 190hp and 300ft.lb of tq.

A 305 is widely regarded as an excellent boat ancor.

Currently i have a stock 1994 SBC 350 block and rotating assm. The pistons a Dish pistons with 4 valve relief cut into them. I think that gives me a compression of 8.75:1. Since my goal is to get 300hp at the wheels would it be a good idea to switch out the pistons with a set of Dome 0.125 pistons which would bring my compression to somewhere between 10.5 to 11:1. The cost of the new pistons is only $170 and seem like they would provide a good jump in HP. I will be running a set of Vortec heads, and Holly 600cfm carb, and a Comp cam Xtreme Energy 268 cam. (Duration @ 0.050":224° / 230°; Max Lift w/ 1.5RR: .477" / .480") The pistons i want to buy: http://www.ebay.com/itm/STD-125-Dome-Pistons-350-sb-Chevy-5-7-Rod-Coated-Skirt-sbc-Speed-Pro-H618CP-/170739946851?_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D5%26po%3DLVI%26ps%3D63%26clkid%3D5515721386079550418

I sent and email to summit customer service to help me pick a cam and below is the cam they suggested: http://www.summitracing.com/parts/CCA-12-222-4/

kool cant wait to see the cam spec for your SBC. I'll look into the screw in studs and guide plates for the Vortec heads. I'm not sure as to what intake to use right now as i would like to be able to close the hood without crushing the airfilter.

Ok guys here is the play so far: The motor will have a stock bottom end with all new bearings and flat top pistons. I will be using a set of vortec 350 heads. I would like a cam recommendation that will allow me to make between 300 and 325hp.

My car currently has upgraded brakes, coilover suspension, thicker front and rear sway bars, strut bars front and rear, 275/4017 tires on the rear and 255/45/17 on the front. Are there any shop drawings with measurements/instructions for all the stuff John C mentioned?

thanx for the answers...looks like my 300hp sbc should be fine with the stock datsun monocoque for now.

Since i'm planning to do a SBC swap into my 240z; thought i would ask the question before i twisted my car into a pretzel. How much power can the stock 240z frame/monocogue take without addition reinforcement? I'm currently planning a SBC 350 putting bout somewhere between 300 to 350 hp at the wheels. I have yet to buy the cam and heads; but i have the block and the rotating assm. complete.

I bought those off Ebay. I think they are a 12 led cluster. Those are stock gauges with speedhut gauge faces.

thanx bro

quote name='Litman' timestamp='1322525050' post='968633'] Wicked nasty stance. Love it!!! Nice job doing all of the work yourself. Gotta respect that. Since you don't have a build thread I'm going to let the questions fly: Front and rear rim size and offset? Front and rear tire size? The rims are Rota RB's; 17x9 (-13 offset) front with 255/45/17 and 17x9.5 (-19 offset) rear with 275/40/17 tires. What, if any, cutting/rolling did you do under the rear flares? I had to do the standard cutting required to have functional ZG flares. I think there is a thread in the "body work" section with a step by step guide showing how to do the cutting. How much clearance do you have in the rear at the pictured ride height? I had 3/4" clearenc at the rear. I have since raised the rear up 1.5" I post some pictures of the car with its current stance soon. Thanks in advance for your response.

The flares are regular ZG's and te spoiler is a sparrow tail. I have decided to just to a 350 build. I will not be doing the 383 after all. Also after reading a bunch of reviews on line i have decided to not use pro comp heads as then seem to be cheap for a reason. Do you think a set of vortec heads would get the job done? Also how much TQ would i lose by using 210cc heads; I ask because they are a set of brodix heads for sale locally with 210cc intake port, 67cc chamber volume, and the valve size intake is 2.080 and exhaust valves are 1.600. Professionally ported have a 1206 intake gasket on them and there ported more than the intake chambers on the gasket. As i stated above i will not be using pro comp heads as they seem to be very low quality heads.

yes but to do a stroker i'll have to get the block machined to a .030 over bore which will probably cost between $500 to $800 in addition to the cost of the crank. Unless i can do a 383 by simply clearancing the engine for 3.75 stroke using a carbide bit and a die grinder.

I'm going to do a V8 swap into my 240Z. As with just about everyone’s build the idea is to keep the cost down and get the best performance/dollar possible. The tranny is going to be a T5 from a V8 camaro going to a 4.11 R200 open diff. My Target power is approx 300hp/350tq at the wheels. (1) Junkyard 350 short block with stock oil pan. I’ll be taking everything apart and reinstalling it after a good cleaning with new bearing. I would like to not get the block machined due to cost.

I especially would like to try and save a lil money by getting a cheaper cam.

got what i need thanx Guys

At this point I'm on a shoe string budget and cant really afford to do a RB or JZ swap.

I need a electric fuel pump and regulator for my 240Z L24 with twin SU's. Let me know if you have one for sale.

The car is looks good but needs a lil more power under the hood. I am strongly considering building a 350 SBC and swapping it in place of the current L24. The goal would be to have 300hp/300tq at the wheels. The only thing holding me back is the fact that i love the sound of my current straight 6 and am not sure I’d like the sound of the SBC as much. I'm currently debating between the high compression L28 motor or a 350 SBC. The HC L28 would only give me around 170hp at the wheels but would sound awesome; the 350SBC would give me 300hp but would sound like a truck motor.

Just finished color sanding and buffing the car. Thought i'd share a few more picture. After And a few pictures of the interior:

I was luck enough to be able to borrow a Devil Bliss GTI gun from a friends bother to paint my car. You are more than welcome to PM me with questions; i'll do my best to answer them.
