You east/central boys are up late tonight! +2 on the 351C nodular iron cranks. I just finished a 1970 351C build for my best friend. Nodular iron, and one year only 1970 CJ heads. It's been fired and being broken in now, but he went the sissy cam. Our plan is to run his 1970 Mustang notch against my 1970 Swinger 340 with my 408 on the back roads of eastern Washington late this summer.
