360 Motor Mounts

I been told that you have to change the passenger motor mount on the 258 6 cylinder to make the 360 work.Is that just changing the 258 mount to a 360 or do you have to weld.Also any fabrication to the passenger side 360 frame horn.And does the drivers side frame horn just bolt up to the 258 mount.

Re: 360 Motor Mounts

you should buy the new ruber motor mounts for a 304 in a CJ, then you can easily modify your 258 passenger mount to work with a AMC V8 block.

good luck

Re: 360 Motor Mounts

Keep in mind that there are three mounts per side to mount the AMC motors in Jeeps. There is metal mount that bolts to the motor, there is another metal mount that bolts to the frame and there is a rubber mount that is bolted between the two. Given that, you have to change the rubber mounts to AMC V-8 mounts. The driver side frame mount can be retained and will work with the new V-8 rubber mounts. The Passenger side will either have to be modified or you will have to buy a V-8 frame mount. The main difference between the passenger side I-6 and passenger V-8 mounts is the off-set in the mounting holes for the rubber mount. The I-6 holes are in the middle of the mount and the V-8 holes are off to the right side (closer to the firewall) about 1/2". When I mounted my 360 in my CJ-5 I had to make new mounts as even the V-8 mounts did not line up. From what I have been able to find the V-8 frame mounts are getting harder and harder to find. Good luck.

Re: 360 Motor Mounts

When I done mine I think two of the wholes lined up with the frame wholes so then I just drilled out two more and it seems to work good. If you do this make sure you use a metal whole saw. Works alot better then a drill bit not to mension alot faster.

Re: 360 Motor Mounts

Or you could use the M.O.R.E. mounts and not drill anything. Just bolt them up and go. They're two-piece mounts.
