I am Mopar thru and thru, BUT the BEST small block ever designed/ produced wears a Bow tie.

Who told you that?

Let's see.

Short deck
Piss poor rod to stroke ratio
Worse bore to stroke ratio
Cam closer to the crank
23* valve angle
Junky assed stud mounted rockers

GM used the softest cast iron out of the big three. Ford was a bit tougher but the Chrysler's had the best cast iron for production blocks.

The ONLY thing better about the SBC was the oiling system.

Just change the valve angles and the same basics apply to the BBC.
