And for the sake of correctness for anyone reading this, the Edelbrocks(RPM) still have the round port design which still has limited exhaust applications....
There is nothing "limited" about round port exhaust applications. Either buy original long branch round ports or R.A.R.E. modified reproductions or round port headers. Those are the same choices you have with D port, other than the low performance log manifolds. As for E-heads, it seems there should be some applications by now.
Nowhere in this thread did anyone question the improved design of the 1969 RA IV. It, like the 1968 RA II, was built with more performance in mind.
The 1969 "Ram Air package" was a toy to add to a 400 HO, which offered not much more than the standard 400 4bbl. It's not a "Ram Air Engine" by any performance benchmarks. Go back and read some road tests of the era.

None.
