My car has no a/c, no ps, found two GM part numbers for it, 3837810 LV 35-1/8 "

and 3837810 sv 34-7/8 ". Which is the correct belt for my car?

Which engine/horsepower?? The difference may have to do with differences in pulley diameter/depth due to engine redline.

Paul, I went through this question with my L71, and there are several prior threads on this topic. The problem is the repro belts out there are not exactly to spec and may not fit. It turns out Quanta has the most reliable/correct sizing on these from my research. For my L71 the correct belt is the 3837810SV (the SV means short version, the other belt LV is the long version, too big for my car with stock pulleys). However, all SV belts are not the same! So I found the Quanta one to be correct fitting, it is their number 29-B-084B can be found here http://www.gastanks.com/1966-1967-Co...nfo/29-B-084B/
