Re: 66 gmc ls swap...need help!

without pictures it is hard to help, but if you do have big block frame mounts and using the DD adapters, the frame mounts could be your issue. BUT, the BB frame mounts are NOT factory '66 year model parts. Those mounts did not come out till the '67-'72 body style iirc.

LS swaps in these trucks are relatively easy. What makes them hard is the vast assortment of adapters and frame mounts that are out there. Best results happen when you use the adapters and frame mounts from the same source in my opinion.
