I used to be an apprentice tech at a Pontiac dealership long long ago before I moved to a Cadillac, and then a Saturn dealership. I acquired a supercharger that appears to be an M90, but the snout is very short. I have taken it apart and its somewhat clean and Im sure with some new bearings can be a nice piece. My question is, does anyone know if the 3800 ever came with a short snout or is this from another motor? I also measured the pulley and it is like 2.8 inches, very very small for one of these. Other than the snout, it is identical to any other M90 Ive ever seen. Keep in mind I transferred from that dealership in 2002, so its probably a few years older than that. Any help identifying this would be aprreciated. Also, if anyone is interested in it, make me an offer.

more than likely a series 1 blower, mostly useless.

I thought the s1 s/c 3800 came with the short snout.

I have the same blower sitting at home next to a stack of Duke parts....

What you have is an M62 blower from the 91-95 vintage 3800s which were Series I. It is the size blower used on the 2.0 Redline Ions and Cobalt SS models. It supports up to 250 HP in usual applications.
