The DRCE3 head (WJ's choice) and the Mopar head are closest regarding valve rotation, the Mopar block is longer than the GM blocks though, a slight disadvantage. Why is the mopar block longer? The bore spacing is the same...and IIRC, the rear overhang is very close. Just wondering. Not sure why, you'd think Mopar and Ford would have looked at what's winning races and learn from it (like Toyota did before casting their nascar blocks). Yes, all are 4.900" bore space, but left bank to right bank bore offset is more on the Mopar, and the Ford is even more IIRC. More bore offset makes for a longer less rigid crank. Well since the width of the rod journal, width of the connecting rod's big end and the bore offset are all interrelated just how many thousandths of an inch are we talking about?
