Almost time for the machinist!

With a new crankshaft and pistons I recommend you have the rotating assembly balanced. 65'

I was under the impression that with the refurbished cranks the balance didn't change because it's a factory crank that has just had the journals cut and polished?

To answer your questions..........cleaning does remove paint.......blocks are baked in an oven to burn off grime and then shot blasted, when the block comes out of the shot blast cabinet it looks like a brand new piece of iron

Go with the least over bore as needed to clean up cylinders and piston availability; you can't overbore far enough to make any real difference in power as a result of displacement gained, vrs power lost to thin flexible cylinder bores, thick stable cylinder walls make power. A sonic check can/will tell you much. Buy your pistons before you bore the block so you have them on hand to measure and fit them to their respective cylinders......

Good luck

That makes sence but what if I get .030 over pistons (what I want) and it takes .040 to get the walls corrected? Then I gotta buy more pistons lol.

What cha' buildin? Sometimes overbore depends on what pistons are available. A 318 may only have .030 and .06 over pistons available. The same goes with stroker kits. They may not have the more uncommon.020 or .040 over pistons available. Yes, the machine shop is a very exciting step in your engine rebuild.

Building a 360 using speed pro h116cp pistons I'm gonna start a engine build thread soon I was kinda waiting till I get closer to final assembly. .030 is my goal because of the piston weight.
