[Chevy454]

No idea, Steve...the Chevelle had a CE L72 in it, but had a hydraulic camshaft, allbeit a good one...but it also had headers, but was an automatic. I would feel comfortably saying the Chevelle was a low-13 to high 12 car on the street tires, because it was a no-nonsense "get out of the hole and get gone" car, and it would run with our Y-Camaro, which at the time was running low 13s. My guess is, the low miles (7800 when we had it) kept it all fresh, and the big tube headers tied to the factory chambered exhaust was like a fine symphony...I'm getting goose-bumps thinking about it! That thing was a MONSTER when it revved! I miss that car...and I can still remember dad giving thrill rides to the locals around here...load up 3 guys, pull out of the shop, and from a roll kick it sideways for 100' or so...
