Just picked up another boat and the motor needs reassembly.
454BBC
Has pistons with it, and I'm foing to calculate compression.
Their .020 over pistons and next to the wrist pin their is the only other number I can find
H518C
they have a slight dish in the middle.
And what's the best way to tell if it's cast or not? Thanks
Tony

Look at the underside for a manufacturer emblem.
