The engine is a 76 455 with 6H heads and roughly 76k miles. I saw this on the St. Louis craigslist so it likely is the same engine.
The engine appears to be in fairly good shape but finding a decent set of heads seems to be pricey. Is the 455 worth the extra cost? The low compression, 7.6, has got to be a performance killer and most heads will put the compression way too high as you stated.
This would be for the street. The car presently has a TKO500 5 speed with 4.10 gears in the rear. I also have a 2.78 posi rear so the torque of the 455 was attractive. But I suspect the current gear would be too much for a lower rpm engine. Thanks for all the responses. Tom
