Thread: 350 t90 gearbox

Tweet

Hi:

I am building a 1975 CJ5 with a t90 gearbox(3 gears) to a 350 GM. Someone did it before? How they put the gearbox to the engine.

thanks

Novak Adapters sells a conversion.

Here is a link to their T90 page, at the bottom there is a link to the GM engine conversions

By the way, are you sure that it is a T90? Starting in 1972, Jeep was owned by AMC and the transmissions were T15, T14, or T18.

Which transfer case are you using?

I have a standard 1975 cj5

Export vehicles may be different! In the USA, for 1975, Jeep CJ5 had either a T14, T15, or a T18 (four speed)

Since yours is a 3 speed, it is either a T14 or T15. To tell the
difference, the T15 is longer. Go to this page for a picture description of each:

You should have a Dana 20 transfer case with a single lever.

Is the vehicle a six cylinder or a V8 right now?

It used to be 6 cylinder, but I have a 350 , that I want to install it.

To be correct my Jeep Cj5 is 1976 assambled here in Costa Rica. But to search for parts I search for 1975, because I have dana 44 rear for example.

thanks

It is a really common sway that makes the jeep pep up a bit. There are companies that make headers for this application too.

With my description with gearbox do you think I have?

thanks

Again, go to this site and it tells you how to identify transmissions.
