Ok, you pulled my knob Agree for the most part. Use what you know and like. 850 holley doesnt make mine any faster. If change rear grs, and tune for it, 11.5's. Up compression 2 pts and tune some more, 11.0's. Dont want to pay the price for fuel since cruise more then race. Drives the chevy dodge ford guys nuts when they see me pump'n 87 octane Reguardless, over 500 hp, need larger line and better pump reguardless of carb. Hmmm...Pontiac thought they where fine for RAIV's and SD455's. BTY, quite a few guys run 10's with q-jets. Stacy McCarty runs 9.80's with a rebuilt junk yard q-jet. Granted, his car is exotic.
One last point on q-jets vs holleys for street performance, or just strip. Once set up correct, dont even need primary needles. Need more/less fuel for weather conditions?, just swap secondary needles(1 screw on the hanger). No gasket worries, no gas drain'n or spill. Holley have to remove the bowls to change jets. What a mess. And have spare gaskets on hand jic.
