Whew! Got the last piston out of the donor 235. Remarkably, the cylinder walls look like they'll clean up nicely with just some honing. As hard as the pistons were stuck, I'd have expected significant pitting.

We (pop-in-law) also just realized we're gonna have to pull the 216 out of the truck before we can reassemble the 235 (from '51 sedan) so we'll have the 216 front cover with the correct front motor mounts.
