440 cylinder bore bevel

Not a big deal as long as your top ring doesn't get into the bevel.

Need some low end, install the cam advanced as long as you have valve to piston clearance. If it's cut on a 106-108 LSA, install it in the 100 area. It will boost dynamic compression and help low end.


x2. That bevel is usually made by hand so there's some difference block to block and sometimes bore to bore. So long as the top ring doesnt get into it, it's not a big deal. If you cc the piston in the block using the 1" down method you can calculate how much volume that space and the space over the top of the rings has and what it does to you true static compression ratio.
