socal is right, you will never know by asking us, you will have to find out for yourself. there are WAY to many variables in racing... rider weight, riding skill ect...
for instance, last year i was riding majicmikes rap770 on alky and could hardly get beat by anything, I was beating 421 cubs on the thing, I am only 145 lbs and can ride the shit out of most things... when mike rode the 770, it was about half as fast because of his weight... needless to say again, there are too many variables to get an upfront answer on a forum on what is faster then what.
