Project 383

[Jarhead79]

I think I answered my own question here with this, came from Super Chevy:

400HP 383 Engine Specs
Bore x Stroke 4.03x3.75
Compression 10.1:1
Cam: ProComp Hyd Roller
Lift 0.552/0.552
Duration 231/236
Lobe Sep: 110
Heads: Pro Comp 190cc aluminum (as cast)
In/Ex Port Vol: 190cc/72cc
In/Ex Flow: 245/190 CFM @ 0.600
Valve Sizes: 2.02/1.6
Chamber: 68cc
Intake Manifold: Pro Comp Dual-Plane Qualifier Plus
Carburetor: Holley 750HP
Header: Hooker 1 3/4
Oiling System: Stock

I'm sure I won't be doing this exact part recipe, but I think it's something to go by as far as numbers go.

I guess I should state what I'm thinking I'm wanting, right now it isn't a daily driver but it gets drivin a lot, but every so often I want to go to a test and tune night at our local 1/8 mile track, probably never see a 1/4 mile track since the closest is about an hour and a half away. while 400hp is my max goal, I'm also looking at best torque range, is around 400 torque as easy as 400 hp?

Well take em to gateway sometime

I may be wrong I thought you could get 202 vortecs

I've been to gateway before for midnight madness, I'd make the trip but not every weekend, Bentons track is cheaper and only 30 mins away! Lol

With a small block stroker, a mild-medium one, I would expect you to eclipse your torque goal pretty easily.


I have a similar build in mind, a street/strip truck. I feel confident that with my 400, some Vortecs, a cam, 3.73 gear's, a set of Caltrac's, and some DR's, I can get a low 13-high 12 out of it.

There are Bowtie Vortec's with 220 cc runner's, but they are way pricey now.

Compared to aluminum?

About the same, http://www.strokerengine.com/VortecHeads.html

I'm pretty certain they are actually discontinued. The lure of Vortec's is you get a whole, assembled, pair of head's, brand new, for under 500 bucks.

IMO, once you get up to 7-8 bucks, you may as well be looking at name brand alloy head's. I would avoid Promaxx and the like.
