I'd like to tune my 428 for more low end throttle response and could use some help! It is in a 2500 lb cobra replica and seems to lag a little on the bottom end....up to 3000 rpm. If I launch the car leaving at 1500 or more there is no problem but if I let the clutch out and put the petal to the floor it will break the tires loose but just feels sluggish .
Engine: 428 .40 over,10.5 comp, C4 heads w/cj valves ported (280 cfm @ .600 lift) Isky 8005a springs, MR 2x4 w/600 vac holleys, Ford dist with Petronix 18 int and 38 total and Comp 282S cam....WR top loader and 3.50 gears.....any suggestions?
