How many of you would buy an aftermarket block in low deck height. Aluminum, cast iron, up to 4.500 bore size.

How much power are you trying to make? N/A? I'd be interested to see how your experiment turns out.
Im not sure, I'd like to do eventually 500 ci with 3.91 stroke with killer heads b1 or -1
900 HP would be a goal but damn, it's still a stock block. I have seen stock block survival but unsure their longevity.
I have big dreams and the opposite in budget so I guess, in my case I'll have to learn the hard way or be successful lol
