My bad I was rushingbecause I was posting from work. It is not what I'm looking for. The Aluminum blocks are good for more than 1500hp (not rwhp). I heard that steel block will make more power at those levels due to distortion with the aluminum blocks, but I have no intention to go there.
My understanding was that NO machining is required for a 402 build. Now most shops will do some clean-up work, but no clearancing is required.
