Need 318 Gurus

Generally, no you cannot mix or match or sub the accessories from those two "generations." The orange, the earlier type was used up to ?70? or so, and the blue ones were the type after. The pulleys, brackets, balancer, just about everything is different.

Those rocker arms are a find. They were used on 273 engines and are the only factory small block rockers there ever were, except for the 340TA engines, and those rockers are different. If you EVER think you will use those FIND OUT what lifters are in there. The pushrods are different length between hydraulic and solid lifters

I would check over the orange engine. It may NOT be a 318.
