Sold new. Beginning of '78 they just bolted the TQ intake/carb on top of the 318 heads. Then they put the 360 heads on with the combo. You can go to any 318 4bbl, common in ramchargers and maxi vans, especially from '81 -84 and it will have 360 heads on it. Cop car diplomats with the 318 4bbl will have 360 heads as well. I've owned them, and know others that have owned them as well. these performed very well right out of the box, but were choked as well with single exhaust, and cats.
