What would be the recommended piston to wall clearance on the 530 block, at .040 over? I'm thinking .005 to .006". Is that enough on a 6500 RPM motor? 13 to 1 C Ratio, Stage VI alum heads, Roller Cam, tunnel ram. I want to run them as tight as practical, to reduce piston rock/slap. ICON 823-040 Premium flat tops.
I am assuming based on the math that this build takes a 4.25 inch crank, 1.12 compression height, and rods in the 6.7 inch range. I wasn’t able to find your piston listing, but haven’t tried too hard yet.
