'70 W30 Olds had better flowing cyl heads than std Pontiac D-ports, about 25 cfm better on the intake at 5.00 lift measured at 28".
Negative... heavier rotating mass for the Olds.

Want to compare the '70 GTO 455 to something comprable, compare it to the standard '70 442 455 engine.

I agree. Better comparison. I never did see a what a non-Stage1 '70 Buick GS ran stock ( I've seen them run real fast today ), but it would be nice to compare to the Stage-1 too.

It's too bad Chevy grabbed all the good HP numbers while BOP's got "politically correct" ones...I mean... if it was all over in a year anyway, why not let them go out with a bang? I share Lloyds sentiment in wishing Pontiac had made a "RamAir IV 455".
