So while poking around my truck I've now found I have a TH350 not a TH400 as PO normally said AND to really top it off.. I pulled the serial # off my carb.. some funny results..

The number I got was:

1708-5-5-8-6

Which basically means:

1708 = 1980
5 = 1985
5 = Cali Emissions
8 = Checker and Marine
6 = Auto transmission

Upon doing some reading it appears Checker and Marine is exactly that a marine company so it perhaps looks like my Qudrajet belongs on a boat ...
