Push Rod Engines

I dunno, I'd love to see the OHC design used on the old dodge 2.2/2.5L engines recycled to the top of a V8. Bet it wouldn't take much too much room or make the engine any taller. Not to mention the benefits of losing pushrods, rocker shafts, rocker studs, etc.. no trashed angles caused by cheapass bean-counters reusing old core boxes, the entire valvetrain could be serviced by removing the valve cover and the heads could be made to flow to the moon! Less reciprocating mass would also open up a lot of RPM potential.
