I've seen a few threads about this issue but a lot of them were left unanswered or didn't have a great solution to the problem. I have a new UMI K-member, Moroso 62510 and 62610 motor mounts and ICT billet LS adapters. No matter what I do I am unable to get the mounts to line up. I've read about people altering the K-member which I'm trying to avoid at all costs. I know UMI sells a small block to LS adapter kit for the K-member but I'm not very impressed with the design. I was wondering if anyone had other solid SBC mounts suggestions that would work with this K-member or if anyone had any luck getting these Moroso mounts to work? I've attached photos as to what I'm looking at. I appreciate the help!

 

Mix matching engine mounts with various brands is always challenging. I went through the same thing. In the end, I used the UMI solid engine side mounts along with their LS mount pads for the K-member. Everything bolted right up.

 

It might be my only option, but between the UMI lower mounts being slotted and all of the weight from the engine hanging off the end of the mount I didn't really like that design. With the ICT billet engine adapters the mounting holes on the end of the mount place the engine in the same area where the small block was located but still gave you other options to move it forward or backward with other mounting holes instead of slotted holes. It would also put the mount directly above the cross member and a thicker billet aluminum would have more rigidity I'd imagine

 

As long as you have the transmission supported there isn't any cantilever affects of the engine weight over the mounts (same goes for any stanchion style mounts). There is no moment arm and they are loaded in straight compression. The slotted holes allow for fine tuning the placement.
