i obtained a new crate E-58 360 engine and transmission assembly in mid year 1978. [july/august time frame]
it came with a "build sheet" [which of course i can't find at the moment] and "premium" stickers on the blue valve covers.
it had a roller timing chain set, but i replaced it with one that had the multiple key positions.
i advanced the cam whatever the timing set had, just using the dot-to-dot, and that engine ran great in my 38 plymouth coupe !
i ran that engine/transmission for a little over 10k miles, then a guy bugged me enough to buy the car [without the engine/transmission], so the E-58 combo has been on my rack for many years now.
if it were to be installed into something else, it would need to be freshened up.
of course if that happened, a different cam, new aluminum heads,.............you know. mission creep..........
