Still working on the push rod angle. Leo Santucci told me when he does SBC chevy heads the push rods end up outside the block. They make offset lifters and all kinds of funky push rods with angled ends. I need to call Mike Kirby next week. Leo told me Mike did a cantilever lifter somehow. With all you smart people I'm hoping this can be done. It will be be cool if we can pull this off. The bore spacing is the same. Thank you for your time.
