The Stovebolt Site Forums The Shop Area Driveline TH350 Info

Here is the situation...My local tranny guy says he has 2 TH350's in stock.One is a "short shaft" and one is a "long shaft".He also said one is for a car and the other for a truck..so the question to all is wich one are YOU using?
1.Short/Long shaft?
2.Car/Truck model?
BTW...1949 Chevy 1/2 ton..upgrade to 250I6..in process of open driveline.

they are the same inside, just a longer tailshaft. QWere used in trucks, station wagons, big cars.Use the short one.

Thanks Tommy ...I appreciate your reply and the info. Every bit of info helps since i'm new to this. Thanks again.

I would also choose the short shaft most of the time as it is a bit more desirable to other people if you were to change something in the future and wanted to sell it. In a pickup it doesn't matter as much, to me anyway.

One variable to consider is the driveshaft length. I will usually get a used driveshaft from the junk yard and shorten it. I prefer the one piece shaft and the common lengths (cheap) might not be long enough to reach the short shaft trans, especially if you have a long bed. You might source the driveshaft and rearend before you pick the trans since you have a choice. As for which model of vehicle to source the shaft from, look for a 73 - 82ish chevy pickup, right before they put the OD in them. The splines and driveshaft yoke for a TH700R4 are the same as the TH350, but the 700R4 is longer by a couple inches. So, the longest stock driveshaft that I have found was out of a late 70’s long bed GM pickup.
Hope this helps,

The TH350 with the 6 inch tail shaft is very close in length to the 200-4R.

The TH350 with a 9 inch tail shaft is very close in lenght to the 700R4.
