I hear you Amervo, I'm about ready to do a chebby myself. It's proving impossible to find a "reasonably" priced 455 core. I just assume do an equivalent build on a 454 and let 'er rip. Though as I sit here right now I'm going to clean up the 350, maybe drop a 400 crank in and call it an engine until I can get what I want. Getting what I want also includes the cabbage for said desire.
