? about that 3.65” crank

Iv never really ran the numbers on a 318 before I did all that math when I was planning my 360 build this is the first time I ever done it for a 318 a 318 comes out to a
1.822 compression distance
A stock replacement piston for a 318 has a
1.741 ch
Thats.081 in the hole. That seems like alot no wonder 318 are so low compression. Lol
