14.45 with 12 sec combo... HELP

Glad to hear you got the ProComp intake, If you didn't get a 1/2" spacer (wood/plastic) I would get one of those as well

Bump your initial timing from 5* - 12* to start - set the total to 36* launch at the highest rpm you can on the foot brake (on the edge of the tires breaking loose), shift at 5,500rpm and trying working your way up in 100rpm increments to 6,000rpm to see what it likes..

Also agree - jet it down to what was suggested (70/?75?) - a AEM wideband is a life saver for carb tuning when you don't know much - it costs less than the intake you just bought. Have to weld a bung in an exhaust pipe, closer to the header the better, then +/- power and you can tune it and know which way to go(rich/lean)!

The Holley 750 carb I had on my Ford 302 was straight off a 500hp chevy 383, only changed the pump cam/squirter and of coarse tuned the idle for my motor - internal parts were not changed.. ran the best it ever did..
