318 Build Carb Tune Questions

I hope those heads are closed chambers and the pistons are really close to zero deck and your using a thin head gasket (think good quench) cause if not your in for some tuning challenges with that much compression and smallish cam. Your elevation will help some but it's still a lot of compression for a iron headed engine IMO.

As for the carb tuning I'd start with stock jets and a 5.5 pv and tune from there. At your elevation it should be plenty rich. May have to jet down but it depends on the efficiency of the engine.

What's the rest of the drivetrain consist of? Trans? Converter stall or 4 spd? Gears? Tire size? Car weight? All of that affects tuning and what carb will work best.

When asking for tuning advice remember that the engine is only 1 part in the equation.

BTW: where did you come up with Hooker super comps that have a 2-1/2" collector? All I've seen are 3". Not that it makes that much diff... Just curious.

One last thing. I hope you plan on degreeing the cam in. So many guys ignore that step but in a performance build it's vital IMO. 3-4 yrs. ago I rounded up 4 timing chain sets all good quality but different brands and did some testing and the cam timing from the closest to the worst was 5 degrees diff. And that's just one part of the equation that affects cam timing.
