oldskool:
Since this is a Buick link you may have missed it.
All about RA2 RA3 RA4.
Dyno of RA3 vs RA4 both with iron RA exhaust.
Probably good prep but otherwise stone stock so they say.

Then lots of tid-bits about maybe RA2 is the equal of the RA4, or reasons why not (same ones you gave) etc. Good thread, at tid-bit on each of the 5 pages.

I've tried everything I can think of for data for the Gonkulator within reason - I still get the RA4 about 20hp stronger than the RA2.

I even looked at the intakes - here is a fun link on the 69-71 aluminum intake vs the 72 & service parts intake.

I dont see how NHRA would get factors of RA2=385 and RA4=380, but that's per Dwights old files & the cars fit (except for the mysterious Ben Wolf) so there we are.
