Tom - I didn't mean to hassle you directly. Sorry if I came across a little strong. I have been a consistent contributor as a member of another board dedicated to the OHC. Over the last year or more I have seen a lot of misinformation float across it, and it has irked me more than I can tell you.
One of the worst contributors to the "myth" of the OHC is Wikipedia. Though the concept of the OHC was originally based on commonality to the Chevy OHV, the end product was far from it. There is actually much, much more commonality between the 230 and the 250 than between the OHC and the OHV.
My preferred combination for building the OHC is to use a 250 crank in a 230 block with a 230 1-Bbl. head. We have pistons made to our own specs, we have cams ground to our own specs, and we use rods that are longer (and beefier) than factory rods. The block needs a little grinding and some custom sheet-metal work as a result, but the block skirt on the 230 is actually stronger than the 250. That, and it has cross-bolted main bosses already cast in to the #2 through #6 mains.
Anyway, I digress ... keep your cammer on the road and enjoy the attention it gets!
