All I know is my 410 stroker I changed my camshaft from a 234/238 110 to a 238/242 112 and lost a little torque on the chassis dyno but picked up from 390 rwhp to 425 rwhp . My car is a manual and on the road it is much calmer, less bucking when you come down in the revs but feels much faster, at two thousand revs in second gear when you just step on the gas it breaks into wheelspin straight away and goes straight away to the seven thousand rev limiter until you change gears and feeel much stronger in third gear as well! I did also go from ported edelbrock heads to Trick flows as well. I ran 11.4 @ 120 mph before but have not been to the track to see the final out come!
