Title: Torque converter identification?
Post by: Gearhead1 on October 31, 2009, 04:59:20 pm

I'm putting my 87 SWB with the parts I have on hand. I have a T350 trans going back into this truck, but I cant remember which torque converter went in it. I ditched a T400 from a parts truck and both converters say 350 on them (hand written with magic marker) I'm sure the T400 was stock, but rumour had it the T350 was originally bolted up to a strong engine once. Is there any way I can tell if one of these converters was a performance aftermarket unit by the markings? The bolting flanges/bosses are different. The one on the left came from the T350...I think.

Just flip a coin :D

The one on the left looks like the after market one, looks like the one I put in mine.  The way it bolts to the flexplate and all.  Thats the best guess I have to give you ???

ok got it in case anyone wants to know. I found out I actually have a TH350c. The TC on the left is the one...possibly a B.O.P. tranny.

Does anyone know if the 87's came with TH350c transmissions?

Last year for the TH350C in a pickup was 1986.
