Hello all! The machine shop's just about done with my son's 312 or should I say 318. 292 block with 312 crank turned to the 292 mains and offset ground to 3.500 stroke with Mummert rods (2" rod journal). Topped with some posted "G" heads 1.94/1.54 stainless valves and a nice bowl job. Ultimately, I'd like to top it with a descent manifold. Anyone have a Mummert or Blue Thunder they want to sell? Thanks for your time!
