Any 4-chain setup is pretty good. Poly body (all are 4-chain unless it was an old machine transplant) are, in my opinion, the best Attexes. The poly bodies were used from '76 till the factory closed in the early 80s.
Superchief
Lil Truck (with a G50B or OH160)
Tomahawk (OH160)
and Spirit (G25A) were the available models that were 4-chain and poly bodies from the factory.
