you can build it to a 496 but have a $hit load of compresion to raise
the hspwr and throw in a huge cam, and with the 4.25 crank, a
13 to 1 comp and that bbc would rock, or you can go the way
beast said the dart block come ready notched for the 4.5 crank
and can be bored wider than 4.310, i think it can go to 4.5 not sure
but good luck and have fun when your building it make sure you
make hotrod sounds when your fitting your crank and pistons,
like " Rawwwww Rawwwwww" and when someone ask, you tel
them thats what its going to sound like, ha
