Can I summarize your feelings? You're angry because GM ruled Pro Stock for 20 years until Chrysler copied their cylinder head and started winning. The Chrysler fans were upset that they had a GM head on their Mopar, so Chrysler engineers moved the valves around but kept the wedge. They used hemi valve placement but the wedge is more efficient. GM knew the wedge was more efficient when they built the small block in 1955 and the Mark I in 1959, the Mark II in 1962 that NASCAR outlawed, the unreleased Mark III "mystery motor" the Mark IV in 1965 and the Mark V 10 or 12 years ago. That why the 1970 LS-6 Chevelle held the IHRA A/SA (showroom stock) record for years, because a stock hemi couldn't touch it. The hemi is just plain inefficient burning gas. It's why Chrysler quit putting it in automobiles until electronic engine management. It was an enviromentally dirty engine. In fact, I've heard tell the new hemi is not a hemi though I have yet to see the inside of one. There's also a reason the new "hemi" is 5.7 liters too, care to guess what that reason is? Now you want to call GM losers because Sonny Leonard has gone off on his own and designed his own cylinder head with hemi valve placement.
