thanks for the input, i had one 406 already and i loved it, it made so much torque it was a beast on the street, i may just build another 406,
i like the idea of the very large cubic inch sbc, but i dont have the cash to build one using a aftermarket block, so i am wondering what would be the largest i can build using a gm block,and what size crank do i need to use with it to achieve max cubic inches, because i have heard from a lot of people that the 400 blocks are prone to cracking and busting around the 600-650 hp range
thanks for any advice
