FWIW - There are easier ways to make the power you’re looking for. You’re going to need 6” or longer rods, especially with a stock block. The cam will need small base circle to clear said rods, so you’ll need a good billet cam. That much stroke also requires pistons with shorter skirts so they’ll be rocking more. You’re going to make power but you’ll probably window the block at 7k.



It’s awesome you have that block but it’s going to be the weak link. IMHO a 377, with 6” rods, would be a great high rpm combo for that block, with less side-load on the cylinders and standard base circle cam. You have enough room to make it sturdy and stable enough for high winding. Like a DZ302 on steroids.
