Streetmaster to Airgap

This article , IMO, is not realistic nor representative of HotRodding, nor of our hobby.
For starters, everybody knows that if you have 318 logs on your 9.8Scr 340, THAT would be the first thing to get rid of. How is the AG supposed to overcome that dam. That it made any additional power at all is a testament to how bad the SM is. IDK, when looking at HRM stuff you gotta always be looking at their methodology.
In this case I see AG and headers together, over SM and 318 logs, is 42 hp; which seems reasonable. What if the headers on the SM only garnered 12 hp over logs, and then the AG WITH headers now on the engine, won another 30 over the SM/and headers? That sounds more realistic. To me it looks like somebody wanted to make headers look better than the actually are. In any case I feel the headers shoudda been first up, or the SM never tested.
But what do I know; I'm the guy with TTIs and dual full length 3" cannons on his stock Smoggerteen, cuz yakno, I don't care what anybody says, a little backpressure is NOT good a good thing, lol.
