Which 3 speed box?
Too long for what combination?
How far forward are you going to mount the engine?
Have you got a short nose or long nose front end on it?
What Tcase are you going to use?
Many factors that will contribute to your question.
Turbo 700 can be made to fit, but you'll end up with a tailshaft about a foot long in some cases.
NO, The Gearbox is a different pattern. 253- Depends on if you go with a Trimatic or turbo pattern, you may need to either get the block redrilled to turbo pattern (More common) or use an adapter (Less common and can be more expensive if you can find the adapter).
Turbo 350 is a nice short box, then you'd need an adapter from the 350 - dana 20.
Has anyone done the 253 conversion while retaining the jeep auto???
I have been researching to do this but everyone keeps directing me to a complete holden 5.7l plus auto & swap it all. My idea is to provide my CJ8 with just a little more power & a sweet v8 sound without creating a monster & keeping the original running gear.
It may be possible to mount the T14 to the holden manual bell housing with some simple mods, using the holden pressure plate and a clutch plate that will marry up to the spline and the pressure plate.
I am not sure of this, but it may be an idea wirth exploring if you can pick up the parts cheap.
