Quote: The cranks are the same as a 440 crank and those aren't too bad. I paid $350 for a new Eagle 4340 4.15" crank a couple of years ago off ebay. Now finding a block for a reasonable price, that's tricky.
not quite true. a 440 crank will work, but it's a 6 bolt flange for the flywheel, whereas a hemi is 8.
if you choose to use a 440 crank, you just need to keep that in mind when buying a flywheel or flex plate.
The 6 bolt, 8 bolt doesn't really matter, just because the hemi originally had a 8 bolt doesn't make it a requirement, unless you are trying to use an 8 bolt only 172 tooth flywheel.
The big difference between a wedge crank and a Hemi crank is the size of the counterweights, Hemi pistons are heavier than Wedge pistons so if you try to use a 440 crank with a Hemi rotating assembly you will more than likely have to add $$$ mallory to get it to balance.
I get a kick out of these guys that think they can build a 572 Hemi for 440 wedge money ...
