Roller cam was 1985.
Oil pump was 88. It changed with the introduction of balance shafts in 1988.
There are a few different pushrod lengths.
Keel, I think it'd be easier to answer your question intelligently if you told us what you are trying to do.
I have a lead on new g.m. 2.5ltr crate short blocks 86 and 87's. but they are the ones for the grand am/ buick somerset/etc. that I've read the block is shorter and doesn't have the off set water pump
But if the rods, crank,pistons, etc is the same.. 299.00 for all new parts.. and dump them into my Fiero block.
