Cold air inlet, larger MAF, matching injectors, appropriate stall converter, good exhaust flow, valve springs that match the cam profile, dyno time, consider a more modern cam grind of similar specs. What's your static compression?
PSIG - you seem to have lots of info; how about you come to Michigan and help me put this together?
Cold Air - I will most likely fab something up so I am not pulling in hot air from the engine.
Larger MAF - Yes; does not make much sense to use a larger TB with out the matching MAF. Good call.
Injectors - I was thinking 24lb. seems reasonable for this set up but I planned to do some research still on those.
Stall Converter - I have (I think) a 2400RPM in there now. May have to read and tweek this a bit for my new set up.
Exhaust - I run 2.25 through some sort of performance mufflers (been 10 years, forgot what brand). Plan on using the Dougs coated full lengths.
Valve Springs - The spring that comes stock on the AFR165's are good to 6000RPM. I don't plan on a lot of 6000 - plus RPM but I think in planning for future mods I may just order with higher spring pressure so I don't float a valve at top end.
Not sure about static compression. I'm guessing with a 58cc head and stock pistons, pretty low. Like 9.0:1 maybe? Just a guess. Been a while since I talked "car-math"!
