more specifics
yeah should have been more specific,it was a cam answer I was looking for ,on the other hand I'm sure gt-40 heads and intake are my best bet,don't know specifics on 351w heads what do you have to modify if anything for those I know it's probably not worth just adding a cam but if I did might need to stay in 480 lift range motor is 93 stock long block w/shorty headers 2.5 flows w/ cross over pipe 410's in rear t-5,ignition upgrade,and heavy foot,just burnt out on stock sound
