I'm running a 406 sbc launching at around 5000+ rpm off a transbrake. I run a 1.37-1.40 60' and 4.19-4.21 330'. I run 10.30's consistantly whether I run 126-131 mph. I use a powerglide and went from 4.88 gears to 5.14 gears and no difference. I have a feeling I'm spinning between the 60'-330'.
What do you guys think my 330' should be if I'm running 1.38 typical 60' ?
