Both engines set up with optimum gearing they would run the same. Even in a heavy car the steeper gearing offsets the engines torque. Both engines will be slower in a B body. I have to admit though the 360 is gonna be more sensitive to slightly wrong tuning. For example my neighbor built a high horsepower 302 with afr 185 heads and a decent roller cam. Then he put street gears and converter in it and he can only muster a 13.40 quarter mile. With some 4.88s and higher stall he'd be mid 11s.

And yes 500 horsepower is gonna be easier with a big block. This pissing match you guys are having is retarded. Years ago the sb had the w2 and edelbrock heads not to mention the 4" crank for 300 bucks. Back then it would have been a good argument but since then edelbrock and 440 source have changed the fact that 440s were once expensive.
