I had a sb 400 built about 10 years ago for my '37 chevy pick-up, but sold the truck before switching motors. and I now can't find the paper work on it, I have never run it.
It has a cam with "E8239" stamped on the gear end along with 276-286-H10 and a "U" over a "D" like a trade mark.
Does anyone know who made this cam, or anything about it.
Thanks Pat

The U/D may stand for Ultradyne. Don't know for sure but it may give you a place to start looking. Jon

Thanks, I'll check them out.
