We found one on eBay for $438!
If you're on a super budget, you can use a stock 440 crankshaft (right) and knock a couple thousand bucks-and 80 cubes-off the tab. Or you can score a used ex-Top Alcohol billet crank like we did. It features a 4.375-inch stroke (5/8 greater than stock) and big-block-Chevy-sized 2.20 rod journals. We paid $500 for this Keith Black piece after ensuring it wasn't cracked or bent. Ex-Top Alcohol cranks are fairly common-just make sure yours has a stock-type flywheel/flexplate flange with an integral, or pressed in, centering ring. Some exotic cranks are a little odd and can cause headaches if not thoroughly checked out before purchase.
