Ok,
But you should look at the striped T/A's from 70 till 72...The 455 H.O. is a far cry from your "Bandit of 77 or so. These older engines have all of the Ram air parts from the ram air IV 400 of 67-70. They are worth twice what a "bandit" is, or any other later car, other than the 73-74 SD 455. They are rarer, and command a bit more. But in Pure Stock Racing they are slower as the cars weigh in at 250 lbs more cause the bumper laws changed. They make no more HP that the H.O. of 71-72. The SD engines are the top of the heap for sure and are better able to stand abuse. Internally my engine is more like the SD today. The heads were done by Warren Bownfield at Air Reasearch, and it is fully internally balanced and blue printed to the tune of 2K in machine work in 1980....10 to 1 compression and a rather big cam round out the package. When assembled it was dynoed at the flywheel at 476HP and 580 lbft of torque, at a low 2,800 RPM and it stays above 500 lb/ft till 5,300 RPM and HP peaks at 6K, Not bad for stock appearance with the orginal manifolds in place. But they are factory RAM AIR pieces, and the high rise intake is aluminum too. IF you really new your T/A's you would know all of this already. Mine is pre smog motor and the one's you have owned obviously were not, they were smog motors, choked with pollution controls and the pissy little D port heads. Mine heads are the round port Ram AIR's..
Mark Weymouth in Michigan runs one like mine in pure stock racing, and regularly is in the low 12's in stock configuration, although they run on a glued track. He tells me his moter dynoes at 375 hp, and 500+ lb/ft. of tourge. Not bad for an 8.5 to one motor.
No time to fnd links now, but you sure can, if you've the time...
