Now to figure out fueling. Wasn't sure if this should go here (Given this is the Corvettte that had an LS3) or in the C4 forum since that's what it's going into.
How do i figure out how much fuel I need if i don't know how much horsepower I make? The engine isn't built yet. The Standard Stroker 416 with that camshaft and an intake allegedly made 550 RWHP on otherwise stock heads. How much are the CNC ported LS3 heads going to add? I'm ballparking in the 625 RWHP area. I'm using 1-7/8" to 3" Colletor Long Tube Headers and going to a free flowing true 3" exhaust that will turn down just before the rear axle and use some sort of perforated muffler. I intend to keep the AC as well since this will be a daily driver that sees frequent spirited driving. Will I need to run larger fuel lines and rails etc?
I have no idea, fuel is not my forte. This is on 93, NA build.
thinking logically you need about a 50-55 lb rated set of 8 injectors to allow for any growth in the future
ID select a decent fuel pump, nothing smaller than 1/2" or an#8 fuel lines
reading links helps
be sure to accurately calculate the injector flow rate needed at the delivered fuel rail pressure example on my corvette a 470cc in each runner port injector is approximately a 44 lb injector

for a decent performance engine, that many guys build, I think your generally going to find an engine used on the street having under 450 rear wheel horse power equipped, with a carburetor(S) you'll need consistent fuel flow at 5-6 psi,and 80-110gph ,Holley,G.M. PERFORMANCE, SUMMIT RACING...

when your setting up your cars fuel delivery system, you'll obviously need to know the physically requirements of the engine your about to feed, For your older carburetor, equiped muscle car, this will generally be for most performance cars 5-6 psi of fuel pressure at the carb inlet port, a fuel...
