Butler poly mount fitment issues?
Hey guys. I've got a 67 GTO I autoX. I stuck some butler poly mounts in it last fall with my new engine and noticed this year I wasn't getting a full turn in either direction. It should be noted it was a royal bastard getting the engine in there with the butler poly stuff where there was no issue at all getting my old engine/stock mounts in. The old engine would practically fall in. Anyhow...come to find out my center link is hitting my Canton road race oil pan pretty badly. I never had this issue at all with my repop stock mounts.....so is this a known issue? I'm ready to buy some 1/4" motor mount spacers to hopefully correct this but I'm just curious if there's a known issue here?

I did not have any problems with my 66 GTO, IA2 aluminum block and those mounts. I suggest calling Butler Performance. They have ALWAYS helped me.

I couldn't get them to fit the saddles with an MR-1 block. I sent some pics to Butler in the car where the bolts wouldnt line up on the saddles,and next to a set of stock mounts showing the difference in hole locations. They took them back and I ended up going with solid mounts that fit.
It seemed like they knew there is a problem with some of them.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
