350 Suffix Code help
Just bought a 1978 3/4 ton original old farm truck to get the motor for another project. Supposed to be 350/TH400. Suffix code is TDS. I can’t find it online anywhere. Any ideas?

Re: 350 Suffix Code help
It doesn't really matter much because smogger 350's were all the same from 72-80 something.

Re: 350 Suffix Code help
I've tried several sites online - nastyz28 is my go-to for suffix codes, but I can't find this one listed anywhere.

Re: 350 Suffix Code help
I tried to get a pic today, but I can’t get a clear shot with the alternator and fuel line in the way. Build sticker on the truck door is 6/78. Intake and heads are both dated 6.28.78. Suffix is V0629TDS. (Flint engine plant, June 29). It’s a really clear stamping and can’t be anything but TDS.
