**600hp sbm block limit? Or is it bs!!**
Different pan, shallow like a B/RB. Suppose someone could weld something up with a cast AL pan and AL main caps. A little ribbing here and there, connecting the caps to the cast pan walls..Just thinking out loud. Once everything is tied in, make everything beefier. That or just mill the entire thing out of a single piece of 5" thick AL for a CNC class final project, probably the only way someone could afford the mill time.
