The O-470 is a low compression engine that runs on mogas. You ought to
know, Jay, you've filled our 182 up from the Grape several times now.

Yep, I know. But the OP was asking about which models to avoid, so I
was suggesting that he avoid the later fuel-injected, high compression
models that can only run on 100 LL.
