Ford had a prototype as well. It was more along the Pontiac OHC line. Again, it bolted to standard heads, not sure about the oiling. Ford discarded the idea when they realized that the big hold up on small blocks wasn't there rpm capability...it was head flow. So a cammer conversion added little, except cost and uniqueness. they found no noticeable power difference.
I checked out the ebay link because I thought it might be that engine. The all steel composition of these make it a weight adder too. More weight and no signicant increase in HP. I thought it was neat when Ford did it, but for me this leaves a lot to be desired.
I'm still hoping to find that Tunnelport 302 that was on there a couple months ago...now that is something of interest. Other than the head and intake castings the tunnelport heads used most production parts. The rockers were Y-block items.
