Okay, here are the pictures.
The first issue I had is the Energy Suspension engine mounts do not bolt up flush on the block on the DART engine block because it's hitting the webbing on the block boss.
I did some googling and it looks like a common problem. The consensus is to grind a "V" cut into the engine mount.
I also talked to James Yale owner of Radical Roadster of Texas. He is a Backdraft dealer and buys a lot of engines from Craft Performance. He said yes they have to grind a notch in the back of the engine mount to get them to sit flush because the DART block is much beefier on the outside.
Now to the frame mounts: Notice the nut almost doesn't purchase any material to clamp to. With the engine mount bolted properly to the block, they would sit lower, but maybe not enough.
These pics show my frame mounts have the slot right in the center, which makes the engine mount hang off to one side. The Driver's side is the worst:
Jason asked me to measure my brackets. From my rough measurements it looks like the inside is 3/4" off the frame, and the outside is 3". I sent these pictures to Jason and he said yes, my frame mounts look wrong. They are too high and the slots in the wrong location. He sent me pictures of the frame mounts they make today.
Jason mentioned they build the headers in a jig using these new frame brackets for the Mustang engine mounts, so I want to be sure and use the brackets they are using. He is going to send me new frame pieces, hopefully I can get them and weld them to my frame over the Christmas holiday break.
