what made a RB a max wedge was the head ports and intake ports along with the bigger valves which that crossram engine never had

Let’s not forget the solid lifter cam with adjustable rockers, forged dome pistons, and cast iron exhaust headers. By my guesstimate, their experience with that engine is how they figured out the RB Hemi was going to need cross bolted caps in it.
