I'm assumeing the block has hemi mounts because it is sitting on the k-frame with schoemacher (bad spelling) rubber mounts. I didn't want the motor plate because of the vibration, but I do like the idea of centering the engine. If I used an Alter-K-tion frame wouldn't that solve the clearance problems?

I wasn't thinking about header clearance. Sounds like I need to go ahead and buy some for mock-up.

Also need info on the front of the engine, such as water pump, alternator brackets, and fan pulleys or elec fan???
