not really sure what forum this should go in but i got a 85 s10 pick up 2.8 engine and after ordering 5 different belts and trying to install them finally

gates - k040476 will work.


they dont really make a specific belt to bypass it so i had to do some measuring and ordering. figured id post this up for future searches

 

Um what serp belt setup you got (f-body/s-series) and are you running underdrives might be some helpful info.

Personally I was running a 2nd alt down there but redoing my factory one with a bigger one and thinking of running an engine driven air compressor for on board air and a set of train horns, lol.
