I remember those. Wasn't that bad. I bought it in '72, dropped solid lifters, Corvette racing cam, Eidelbrock manifold, and a Carter high flow 4 barrel carb in it. It moved rather well.....
I still have an 8 track deck on my stereo system in the living room. Still works fine. How many remember it's predecessor, the 4 track player. Had one of those in the car.
