So im building up a 383 stroker, motor is already fully built, its not going in a camaro, its going in a tube chassis and doesnt need any smog or street legalality. and am hoping to make more than engough low end torque with this motor(between 1500 and 3500 rpms)
Its an 89 MaF style tpi set up
So heres my 2 questions-

1. Will accel 36 lb injectors be ok?
2. Will running this Cam with the set up be ok?

The motor is brand new, and has the following parts-
383 block with lt1 rods
cam is Elgin E920P 480" lift 280" duration 110 lobe seperation
Pbm 200cc 64cc chambers aluminum race heads
10:1 compression
edelbrok high flow manifold
siamesed runners
58mm throttle body
Gadelli racing MAF (high flow)
Adj. fuel pressure regulator
fully blueprinted and balaced rotating assembly
roller rockers
1 3/4 headers
And am going to have a custom chip burned for it

Thanks alot,
Cody

 

36# injectors may be a bit to much but they will work with a custom tune. if that is the duration @.50 then it is too big for a TPI.
is that a stock TPI intake or is it an aftermarket setup, like edl, or TPIS?
a cam with the specs of the LT4 hot cam will work good in your 383.
@.5 lift 218/228 duration and .525 with 1.6RR.
if i may, what is the purpose of this motor/car?

 

The duration is 230°/230° @ .050
The intake is an edelbok manifold

Its going in a Tube chassis rock crawler on 2.5 ton Rockwells , with an ultra low gearing set up, so most of the time the motor will be around 2500-3500 rpms rolling at about 3-10 mph

we just droped the motor in yesterday, so were gonna hve to test it the way it is..
Im just hoping the 36 lb injectors and cam will not make it not idle, but i want to get as much as possible out of this motor

 

Okay, its going in a low rpm torque monster type app and spend all its time at peak torque basically.

I would personally run a smaller cam than what u are pondering, even drop a little below the hotcam actually.

Keep it short and build lots of cylinder pressure down low and quick.

Check around the 212-216ish on the intake and 222-224 on the exhaust with lift according to what your heads flow.

Dont waste time or money on Accel injectors, u will thank u later.

Look at some of the ford motorsports/SVO injectors. If running TPI 30# will be more than enough injector.

later
