Hi Bonnie, The only one that will work for the '78 is the TH350 due to length issues. Preferably you want one out of a vehicle that was 4wd so you do not have to change the output shaft to run the transfer case adapter. The company I recommend for al the supplies is Novak conversions. They can assemble an entire package for you to perform the change easily. I'll post a link to the products you'll need below.

I suggest calling their pre purchase line first to get all the info ***-***-**** they can then transfer you to sales.

I've been using their products for quite some time and find they are superior to other companys in the adapter market.

I have looked at that sight but they had nothing to bolt up to my 304 v8 all was for Chevrolet engines. this is kind of spendy for the answer
Jeep Mechanic: K. Wiggins, ASE Certified Technician replied 2 years ago
They do, the first link I posted is for the bell housing adapters for the 304 to bolt to the TH350. You may have been on the page for their Chevy v8 swaps. I can assure you they have what you need, I purchased these same items for a customer a couple of weeks ago. I highly suggest calling verses using just their website to order.
From the first link
Kit 437AMC-2, adapting AMC 304 engines to GM HydraMatic transmissions
Part #: 437AMC-2
Weight: 20.30
Price: $456.00
Includes the adapter plate, flexplate, crank spacer, flexplate spacers, flexplate reinforcing ring, fastening hardware

don't you think the th400 turbo would be a lot cheaper it bolts right up to the engine it is tight but they tell me it works fine what do you think. .I know the th350 is over 3 inches shorter but in the long run it would be cheaper..i have been told if you get a transmission out of a cj7 76 to 79 it works.
