Yes i have aquired a 350 bored .30 over cut for a 400 crank. The the crank is a eagle crank internally balanced with 5.7 i-beam rods forged eagles. Im going with 10.5 compression forged pistons from summit. Im going with alluminum 2.08 valves to boost up the compession to 11.5 to 1. Im trying to get 600hp on motor. I need some advice to get that kind of hp....its going in a 86 z28. I have a 700r4 wiyh a 3200 stall....

You have a .030 over 350 cut for a 400 crank?

And you're going with aluminum 2.08 valves to up the compression to 11.5:1?

So basically you're looking at building a 383 SBC with 600 hp? Assume it's just a street car...what's your budget?

[killab1989]

Well my budget is 300 to 400$ a week. Buying parts week by week. I jus need help finding the right cam, heads, nd intake.....will the eagle i-beam 5.7 rods handle the 600hp

[67-4-fun]

are you planning on racing the car or is it mainly going to be a street drivin car or streey/strip 60/40 per say

[killab1989]

Street/strip. Lik a weekend car basically

[zildjian4life218]

What has been done to the transmission, drive shaft, rearend, tires, and suspension to be able to hold 600hp? You normally don't change valve sizes to change your compression values.

[cool rockin daddy]

OP, go to the library and start reading. 2.08 valves do nothing to raise compression. What on that 86 Camaro do you think is strong enough to handle that power? The 700R4 sure isn't in stock form. Tell us what qualifies you to be able to handle a 600 hp car. You do realize that 600 hp at the flywheel will mean you're "street/strip" car will be all strip? C'mon. Educate yourself, put a REASONABLE plan together, and come back.

A 600hp engine will probably cost you around 10k to build, and you can probably throw away all of the parts you have as they're not even close to cutting it. After you build the engine the car will need another 10k dropped in it to be able to handle the power.

So 20k at 400 a week, you can get it built in about a year.

The next question is do you really want to drop 20k on a 86 z28?

[Blazin72]

You guys are going about it wrong here. Just bolt on a 300hp nitrous kit and run it till it blows up....

Well i got the rear end with 3.73 gears, positraction. well i c everyyone is sayin no on 600. How bout alumnium heads with 2.08 valves 64cc, 10.5 to 1 forged pistons, a cam with a lift of 634 nd a team g intake, nd a 750 double pumper. how much hp wud i be puting out?

Idk what is with the 2.08 intake valve but IMO I would think a head with that size valve is gonna have a pretty big port volume which is gonna kill the low end. I would go with 2.05 if you really want/need the bigger valve. I would think 450hp would be an honest respectable number out of this engine maybe more/less if the cam and heads are sized correctly for the cid, rpm, and application. I haven't had the pleasure to build an aluminum headed 383 yet hopefully soon with finally having a decent job I can put one together.

Edit: Also that rearend is not gonna last very long. I broke mine in my 86 cutlass in a couple months on an under powered 355 with street tires. You will need to upgrade it.

This is where it gets expensive. Everyone wants to make a huge hp motor and they budget for it but then they don't realize the thousands of dollars the drive train and chassis take to make that power get to the wheels and stick.

[cool rockin daddy]

2.08 intakes? My guess is he's looking at Brodix heads.

Seriously, OP, what is it you want to do? You have to set the car up for what you want to do, then build the engine for what you want to do. The ease in which you backed off from 600 HP tells me you're just throwing numbers out there. Have you even been behind the wheel of a car with an engine that puts out a true 350 HP at the flywheel?

Are you looking for a 12 second car? 11 second car? Even less? I personally think that you just want to drive up to the latest Sonic with a dyno sheet framed in neon on the roof.

LMFAO! Good old bench racing.

[ap72]

If you could manage a 400hp engine, which I have doubts about, it will destroy your trans, rear, chasis, and even glass...

I'd like to see that video on youtube though... GO FOR IT!

[killab1989]

Im jus tryin to get the most hp out of a 383 stroker people. Without spending a **** load of money to get it
