Yeah, that's what I show too. They're 0.040" overbored pistons, which makes it about 241 cubic inches. And with the shaved heads, I have about 9.25:1 compression now.
It's a modest increase, but that sets the stage for a few other modifications to improve how this 235 runs, such as headers and dual exhaust.
I guess I won't turbocharge this particular motor, since my compression is up this high. Maybe I'll worry about that on a future stovebolt.
The head's back on though. Hopefully now it'll run a lot better.
