Ok, when comparing a 4.3 to a 350, is it the front 2 cylinders lopped off or is it the back 2 cylinders lopped off?

Wondering if doing the swap moves the trans if you use the stock motor mounts.

Also....if you were going to hook a 4.3 to a th350....what flex plate would you use...the one from a 350 v8 or the one from the 4.3?

4.3 and 350 share the same flex plate, as long as thier both of the same balance (internal or external). As far as mounting, the engine mount location I think should be the same. If not, you can unbolt and relocate the mounts on the engine cradle.

Distance from rear face of block to motor mount is the same on gen 1 sbc and 90* V6's. Essentially the front 2 cylinders are missing.

Cool...I was hoping to not have to cut the motor mounts off and have to re-weld them.

Putting winter plans together for a project.

Are you sure? This my 4.3 Using AA's Bolt in mounts for a 5.7.
Note front is tight but plenty of room in the rear of the engine bay.

I would guess that would depend on where you put the mounts on the frame.

It is bolt in using existing holes on the yj shock towers and the in the frame there is only one way it can go.

That's what I mean....you used that kit. I would have to see where the mounts are in relation to the stock mounts. Are they forward or rearward of the sock mount location?

Here's a YJ with a V8, plenty of clearance in the front and rear.

Here is look at the mount. It's a Novac weld in. Red arrow. The blue arrow points to the front of the rig.

A better look at the mount.

HMMM that motor looks familiar

These are the only other photo's I have with me. The jeep is in Bay City. But the center of rubber pads appear to be about 4 inches behind the shock towers
