What is the biggest engine you can put in a 1987 Chevy S-10 Truck?
You can put what ever you want under the hood, it all depends how big your wallet is.
The oil filter on a 1987 Chevy S10 truck is located on the bottom, right side of the engine. It is positioned on its side to allow for easy removal and replacement. If the S10 truck is a 4+4 with the 4.3 engine, the engine oil filter would be accessed from the top, under the hood in the drivers side front corner of the engine compartment.
