11.90 vs 11.99, thats just under a 1/10th of a second. I'm not a drag racer, I only made a few passes on each motor just to get an idea what it could do (without risk of breaking anything
). I forget the trap speed right now but recall that it was several mph faster with the BIG motor.
Question might be:
How many more horse power, generally speaking, would it take to gain a 1/10th in the 1/4? A lot of the guys at the track were trying to shave a 1/100th here and there and happy to get it.
I just built it like George at "Gessford Machine" told me to.
A windage tray was added and the custom pistons for 'quench' were the main new additions. George spec'd the flat tappet cam. I was still running the big twin 660 center squirters on the new motor as well, which have now been replaced with smaller more street friendly vacuum secondary Holleys.
