I like your project Dead Pixel and your idea of building a mismatched high torque motor with high compression head. I've got a similar project I'm working on for my Serengeti Badger. (Baja section) I'm using an older, worn out, non Hemi Predator block, that I am freshening up with a new rod rings and original CL1. I'm adapting my .070 milled and ported 5 bolt Grayhound clone head to fit the larger dowels in the 212 block and using 1.3 ratio rockers to cheat a little more lift outta that CL1.
