    Hello fellow Jeep J-pickup enthusiasts. My son and I have a 1973 Jeep J2000 that currently has an AMC 360 (which is locked) and the mated automatic with Quadratrac transfer case. Since I am a Buick nut, I have a Buick 350 laying around starving to go into something. Have any of you guys dealt with this conversion? I know the earlier Jeep pickups came with Buick 350s, but wondering what it would take to swap in a 350 Buick and mate it to the existing frame and automatic transmission.

    Im dropping a Buick 350 in from the 230 Tornado. From what I was told, it is not a hard process. Buick has some large funky looking motor mounts for the jeep pickup, and I'll show you a pic. As far as the tranny mate to things, I cruise around the Novak adapters page here: https://www.novak-adapt.com/
    A wealth of info on that site. Your radiator should still work too, if it has that top hose inlet that is angled.

    Buick 350 motor mounts for a jeep truck. Came out of a 68 J truck. 20190624_162712.jpg Screenshot_2019-06-24-16-45-45.png

    Hi there. You should have a nailhead TH400 trans that mates to the 360 with a cast iron adapter
    ring. You will need the correct adapter for the 350, along with the flexplate spacer. Congrats on
    scoring a J truck, here's a few links for homework, Happy Wrenching!

    Thanks. I will definitely need to do my homework. Still on the fence because I have a running 350 Buick engine, but not the mating transmission and proper motor mounts, OR, I can just rebuild this locked up 360 that already is mounted in the Jeep with the TH400/Quadratrac transfer case.

    Thanks for the photo of the motor mounts. They do look crazy different.

    I saw the frame mount photos Lancer318 posted here. Was just wondering if the mounts that bolt to the 350 Buick block are the same as the ones used in A body skylark cars? I also heard the exhaust manifolds are different. Is that the case?
