Hey Dave
30's are good for 300+ flywheel hp.Have seen several formulas in Super Ford etc. and they all say the same thing.However I do remember formula is different for 4,6,8,10 cylinders etc.For our cars 300 hp is a good #.At 5,200 rpm's my a/f ratio was 12.25:1 which is great.
Oh,you asked me about mods.Here's my list.
94/95 S-model
3/4 raised top
Pro-M 77
BBK 70mm TB
custom air box and ram air
89/93 SC pulley
180 thermostat
cool fan switch
IC fan
Hogged out xhaust manifolds
obsolete MN-12 Performance full xhaust
190 fuel pump
I think that's all the engine mods and that comes out to 305hp and 410 lb/ft considering a 15% loss.Oh, and I have never been to a dragstrip.I do some road racing in a track preped Viper,does that count?
