Poly Locs or Mag Mounts?

When you get to shimming, you will need to loosen all the bolts on both sides. I found, that by jacking on the oilpan I could actually raise one side while simultaneously lowering the otherside, kinda spinning the motor around it's crank axis. Then some shims. Then tighten it up before lowering the jack.
The carb ended up a hair off kilter, but that was the least of it's worries.

If I decide to try to shim the engine this is what Im thinking of for shims.. This would work I assume?

I just got cheap replacement motor mounts and drilled the driver side and taped it for something like 5/16" x 20 flathead bolt. Has been working great for the last 12 years and I run a 4,400 stall with drag radials!

I've heard of doing this, I was just unsure of how well it would work. I guess essentially it would be the same thing. I have a spare set of mounts that I could experiment with.

Just my 2 cents, Maybe replace your trans mount first, there cheap. I found my old mount had sagged just a bit to one side. When I compared it to the new one there was a small height difference as well from the old rubber breaking down.

I've already thought about this. Im looking at changing it to the poly mounts. Im pretty sure the rubber on mine is shot.
