originally LA 318 4bbl Engine??

That year probably has a Quadrajet. Carter went out of biz in 1984 I thikn it was and by 1985, all the surply was gone.

Since it doesn't make any sense to get another 318 from a Van or RV, simple bolt on's can get that engine scooting preety good. A high performance build needs to have the pistons replaced for reasonable compresion.

If it is a real 4bbl. engine, the heads are 360 heads with 1.88/1.60 valves and are a very good platform for power.
