How much you think i'll make at the crank with this setup. Do you guys think it'd make a decent difference to spend the extra $200 and put on vortecs (I havent gotten the 305 heads yet)?

What valves in the heads?

With 1.94/1.60's, you should be in the 350-375 GFWHP easily.

(Waukesha? I know someone in Waukesha...)

Should make some power (I'm terrible at saying how much, so I'm not even gonna try ) but I'd reccomend a different intake. That one isn't bad, but you can do better. I'd suggest a Perf RPM for a combo like that. It will be more street friendly than that single plane, and probably make more power too.

Im buying the heads completely rebuilt with new seals, guides, stainless 1.94/1.60 valves, retainers, keepers, and LT1 valve springs. The kid im getting them from actually bought them off this board for his formula.

Yeah, thats what everyone has told me. I got the intake for dirt cheap, so ill use it for now until I go to a hotter combo/or the 383 im piecing together. The loss of low end i dont think will bother be, because i had way to much of a traction problem with 882s, and stock 305 tpi, so i dont want to know how bad the tires are going to spin now. Thanks for the suggestions guys.
