The guy here that had a factory roller cam most likely had a factory th400 in his c10.

I think the TH400 was introduced in model year 1964 for Cadillac and Buick, then the following year for Olds and Pontiac. I don't think the TH400s were used in trucks until the 1970s.

I have seen a few '65-'66 C20's with TH400's from the factory. One was a '66 GMC that came from the factory with a V6 and TH400.

For 1966, the three speed automatic was not listed as optional equipment for C10, as it was for C20.

Yep, not in the half-ton/C10s until the '70s.
