I used to know a chebby guy. He had a 71 Chevelle 496 rectangular port iron heads, low rise single plane, Dominator, solid roller cam 11:1 CR. Ran 11.40's every outing at the track. But it wasn't immune to engine troubles. Broken valve train hardware, very rough idle, can't hang in traffic, overheating, he would never cruise long distances with his 4.11 gears, 4000 stall converter and tempermental combo. Yes it ran great ET's but was not well suited to street duty which is why he went LS eventually. A well built and well tuned Pontiac street machine will always be the best in my opinion and reliable to boot! Anyone of the other brand guys would have to see it to believe it and then they still would be skeptical to see a pump gas Pontiac running low 11's with 3.08 to 3.55 gears, HR cams, 3000 stall converters, Qjet or 4150 cam, etc. We all know there's a lot of tuning and know how to get there but that's not supposed to happen!
