And the 87 is an 87 only block as in 88 they moved to the internal in pan oil filter and balance shafts. This was yet another block change because it eliminate the oil filter port on the exterior of the block (also other stuff but that would be the most obvious). So it gets even more muddied because of that. Im not sure of the non Fiero 89 and up blocks.
Even if you assume all are VIN R, later versions had more changes and often won't interchange parts easy or not at all w/ 87 or 88.
91-92 even have Timing Chains and Grind the Cams for that and block takes chain guide/tension parts.
87-88 Could use the later Head but have to use Intake Man for them too.
Plus FWD cars need different belt map and tensioner to have PS.
Some made "adapters"/mod to fit FWD tensioner... While may seem to work, often they over load the belt and belt or parts driven by it dies.
If you have VIN U or others as donors, almost nothing will fit a VIN R of any year.
Thanks I did not know they had swapped to chains. I will file that away. I had read that you could swap a 1993 S-10 that was more efficient and had 100hp directly into a 87-88 (for some reason probably the fuel line routing but maybe not it mentions only 87&88 for this swap) but this now seems like it would need a lot more than just the engine EG electrical & ECU. Plus probably have mounting issues with the water pump ALT and AC. Also probably be obvious when it was smog time.
