When you start looking at that in terms of reciprocating mass in the Hemi, along with a shorter runner intake, think of the RPM that sucker would have been able to live at on the super speedways, even with the technology of the day. That combination could have lived in the stratosphere with the “Mini Express” mushroom lifter cam if the factory would have kept the rod weight reasonable.
It may be worth mentioning for those that might not know that Just Mopar Joe on the YouTube is building a healthy stock stroke 400 with the intent of using spray that he’s going to be using a tunnel ram on for his ‘68 fastback barracuda. The B engine is my favorite “within reach” Mopar motivator.
