hey guys i just was wondering if anyone was racing with a 383 sbc and what you guys was shifting the engine at. i was talking to a friend and he said he was shifting around 7200 and 7300 with his 383 i have never shifted my 383 over 6800. let me know what you guys shift at thanks mack.
the heads are pro actions 235 208 int 160 exh the cam is comp 630-630 solid roller, but i also have a comp 675-645 solid roller which one would you go with. oh yea the trans is p/g 1.76 ford 9" with 4.71 gears 28x10.5x15's m/t slicks. in a 87 camaro around 3200 pounds.

I would guess with 235 heads and if your cam will rev to 7300-7500 rpm, that is were these heads would have to be to take advantage of that big a head........my 383 sbc with afr 210 heads peaked on horse power at 6800 rpm and my camshaft is good to 7400 rpm.........so i shift out of first gear at 6700 rpm with my glide and go through the traps at 7000 rpm.....works for me, but if i have 235 heads i would have to rev it way higher to gain anything
