Getting ready to do the LS T56 swap finally. I have stock small block frame stands in the 68 and the Dingo Sliders. Which poly motor mounts are you guys using?
Thanks

I bought both for my car along with the both frame stands so I have options. I have seen a lot of conflicting info on which ones to use, I think it really comes done to your setup so its really hard to say which one will work.

I'm still waiting on my motor so at this time I have no idea which one to go with.

Just did an LS3 swap with tko600.

I used the 307/327 frome mounts and Energy Suspension Poly Mounts.

The 350 frame mounts did not give enough pan to subframe clearance and the 307 mounts put the hole about 3/8" higher. Works perfect with the Dingo Sliders.

We used the GM Performance Muscle Car pan (Hummer H3) The Holley or 4th Gen F-body pan may have more clearance and work with the 350 frame mounts.

I think you want the Energy Suspension 3.1114G's with the 67/68 small block motor mounts.

I have the 69 Z28 mounts with the 3.1117G's in mine.
Thanks too all who responded..appreciate the info... Does anyone have the measurement diff in the 67-68 302/350 sb frame stands??
Thanks
