Yes I left the 72 HO out because , and a big disclosure here:
I am only quoting what I have heard from others, I have zero experience with the 72 HO engine. I know there is a large ,well....quite adept at starting threads, contingent of 72 Firebird owners on this board. I have no malicious intent leaving the 72's out, just stated my opinion/experience with these cars..
But have heard the 72 round port heads didn't flow as well as the RAIVs' 614's or HOs'197's did and that 72 was really the beginning of the smog/pollution restriction era on 2nd gens Firebirds.Didn't 72's have a EGR valve or something similar??If I am wrong, then I am wrong. Don't claim to know much about 72's past what they look like, so don't slam me for not knowing.. SD has to be included in round port comparisons due to the wonderful over engineering Pontiac performed as their last gasp of muscular car/performance air. If you really look at it, 71 was the last year for just a standard engine,no pollution controls etc, and Pontiac finally got it dead on with the massive torque from the 455...And if my original post didn't infer..then here is my opinion...I think 71 was Pontiacs hi water mark with Trans Am performance,styling and just simple affordable American muscle.. and would say this even if I did not own one. Personally would take a perfect 71 HO over a RAIV or SD for a fun driver.
