That set up would give you 265.34861718750005 cubes. I had a 77 with 55 horse. Stock stroke, 3 3/4" bore, stock cam, stock carb, stock valves, and stock RPM's. But it had 80 thousandths off the head. Ran premium fuel. Dont bore the sleeves or block or whatever youre doing (unless its already done.) Get murphys roller rockers and intake manifold. Shave the head .0100. 1550 or bigger carb with 770 valves and I bet you will have 65-70 horse. That's pretty good for no machining to the crank or block.

Why not use 550 valves?

Simple: Later (3.625 Bore) 550 engines have larger exhaust valves. I would need to look up the intake valves.
