Whats Next for my truck???

IF you want to lower your compression ratio trade the 243s for 317s. You can get 317s dirt cheap and make a little bit selling the 243s.

Hey where do I find these #'s??? I didn't see any castings on my hads when I had them off.

since you have forged pistons I would go with boost but be conservative with the tuning

There is a little pad on the fwd edge of the head when installed on the passenger side that has the numbers on it.

You can see it in this pic:

oh... I'll have to go double check i don't recall seeing anything.

I'm for the boost

So I checked it out. with the 317 heads my CR would be 9.7:1. I am wanting to do this in steps. So... if I got some 317 heads and a boost cam custom spec'ed for my motor and got those installed would it still drive ok as a N/A truck (before I saved enough for the turbo kit) ? Or would I be better off waiting til I had the coin to do the install all at once?

you would be fine with 9.7:1 the throttle would feel a bit laggy compared to how it drives right now but nothing major i think the 4.8's are 9.2:1 or something like that (some one correct me if im wrong) but i would get a set of 317's get them ported by some one and get you a custom boost cam and swap all that out. then when you have the money for the turbo kit order it and slap it on.

I think I would just try another cam, seems to me that it is way small for your setup. hey if you go to different headers wouldn't mind having though e-bay headers from speed daddy to try out. By the way what gears and stall you have in that rolling sleigh.

I will sell the headers eventually. Whether it be because of getting bigger headers or turbo manifold. Gears are 3.73 and currently running a TB I-6 Stall that will be swapped sooner or later for my Circle D 3200 stall

I feel like just getting a bigger boost cam is gonna make a big difference. Idk if I want a huge N/A style cam, it would probably make it less streetable?

Even going with a big turbo cam, should help out some over the small cam you have. But it will just shine that much more when it is being pushed around by 10 psi of boost!

IMO, you could prob add about 100 rwhp or more by adding better heads, cam, and exhaust. I don't know why you're treating your 383 like it's a 5.3...
