Frequently Asked Questions:

What transmission will fit a Chevy 350?

A Turbo 350, 400, or a 700R4 can all be built to handle that power output. You need to see what will physically fit in your vehicle. Generally speaking the Turbo 350 and the short tail 700R4 will fit all GM vehicles.

Will a Chevy 350 bolt up to a 305 transmission?

The 305 transmission will bolt to the 350, “but” there may be a couple of other issues to work through. It depends upon the year of your 305 engine (can we assume it’s the same as the year of the car?), and the era (year) of the 350 engine.

Will a 350 bolt up to a 4L60E?

It will bolt up, depending on what year 4L60E and what the 4L60E came out of. Also note, that just because it will bolt up, you still need a controller, to shift the transmission, as its fully electric and will not shift.

Will a t56 bolt up to a 350?

It should bolt up to the engine fine if it still has the Chevy bellhousing on it. You may have to change the driveshaft slip yoke or the transmission output shaft to match up. May need a custom length driveshaft. And you’ll probably have to figure something out with the trans mount.


The endeavour to bolt a Chevy 350 engine to a Jeep transmission is a challenging yet rewarding project that blends the robust power of the Chevy 350 with the versatility of a Jeep. While the installation demands precision, the use of compatible transmissions like the turbo 400 and turbo 350 ensures a seamless integration. The process, though complex and better suited for a professional mechanic, opens up a realm of possibilities for enhanced performance and reliability. This venture not only tests the skills of automotive enthusiasts but also promises a significant upgrade in the vehicle’s capabilities, making it a worthwhile pursuit for those passionate about custom vehicle modifications.
