Does anyone know much about the heads on these small engines? Like chamber size and how many thousandths does it take to decrease chamber 1cc. The CR was advertised at 8.7 :1.
Since my '62 Merc is bone stock original I've decided to keep it that way. I'm planning the future engine rebuild. Picked up a set of .040 OS pistons, and in the process discovered they are the same used on the 170 I6.
