MORE V8 mount guys... how far forward did you mount your frame brackets?

I'm just getting ready to drop an AMC 360 in my '83 CJ7 and I did a test run last night to check alignment and it looked like I was going to need a pretty magical shoehorn to make that engine fit in. The back of the block was hitting the firewall and the engine mount was a good 2 inches from the center of the bushing. I had the mounts centered on the 6 holes (i.e. - bolts in the 4 corner holes), but I suppose I could try to move the mount 1 row of holes forward to push the engine forward.

If you are running this setup with your V8 where did you mount yours? How much room SHOULD there be between the block and the firewall?

Well I am Chevy so I can't really help, but there is a sticky about the AMC swap right above where you post. Might find what you need in there. Luv the V-8's

I would say 3/4 -1 inch space at a glance. Take into account mine came installed by the PO and I have an intermediate CJ so I can't speak for the mounts.

Thanks! I actually read that a few times while researching the swap. Very helpful, but this was a little more specific I think.

3/4 - 1 inch farther forward than the stock holes? Not sure I'm following what you are saying. Can you give me a reference point?

I'll be making sure the frame mounts are on the correct side (I'm SURE I did it correctly), and I'll try installing the engine at a different angle and see if that helps at all.

Thanks!

Actually I was hasty in my post -- I meant 3/4 - 1 inch space between the bell housing and the firewall.

I used the original mounting holes with the M.O.R.E. mounts when swapping in my 360 into my cj5. I have around 3/4" clearance.

If you have tried to mount it and know how much more you need to make it clear, just move it forward that amount! I have a SBC and have only 1/2 inch between the distributor and firewall, a little close for my comfort. Also, is there any disadvantage to moving it as far forward as possible - better driveshaft angles - Just let the fan clearance be your guide and push it up as far as you can.

just got done with my 83 cj7 swap with a 360 and used the more mounts and factory holes. Its was tight but went in just fine. If you move the mounts I have heard of guys running into driveline issues, but thats just my two cents.

Did you mount your frame mounts, then put the brackets on the engine, then drop it in? What order worked best for you? I'm trying a few different things - hard part is trying to get the engine to sit straight side to side on the lift.

Make sure you dont have the left mount swapped for the right, i did that once and nothing really wanted to line up.

I mounted to the frame and the block seperate and then ligned them up with each other and slid the bolt through the bracket. Now it wasnt as easy as it sounds though it took my wife and I about 4 hours of in and out and in and out.
