WHICH IS BETTER TO BUILD FOR A STREETABLE APPLICATION ON PUMP GAS BUT CAN STILL TEAR UP THE STREETS?
I'M HOPING TO BE AROUND 500HP ON PUMP GAS.

COULD YOU GIVE REASONS FOR YOUR CHOICE PLS.



if you can get or have either block and its not outrageously more than the other do the 440 its always gonna have more HP with the same build thrown at it as the 383 and the parts will cost the same as will the machine work or what ever...Only time I do the 383 is when im trying to feel/be nostalgic or its #'s matching or I just wanted to be "correct" like say in a 68/69 RoadRunner rebuild id probably use a 383(or do a 440 six pack)...othe than doing something like that or a 383 or 400 stroker do the 440 if you have the block.
