Greetings . . .
I don't see why not. Especially since I am not sure that there is really any distinction between '54 short blocks - or stovebolt short blocks in general. Take for example the transition from '52 to '53. The'52 power-glide engine (equipped with hydraulic lifters) was in used in '53 for stick cars with solid lifters (Floyd Clymer's "Cast Iron Wonder" documents this). The '53 power glide engines were the first to ship with full pressure oiling and insert bearings on the connecting rods. In Floyd's mind this was the end of the Cast Iron Wonder era . . . the stick cars the last of the era . . . the power-glides of the future . . .
1953 was also odd in that a 216 was non-existent in a car - but could be had in a truck.
By 1954 all of the short blocks where full pressure oiled cranks. So I don't see why cam/lifters/push-rods couldn't be interchanged TOGETHER freely . . .
But curiously there are two casting numbers 3835949 & 3835491 but me thinks one is for cars and the other is for trucks . . .
