update:
Thursday I dropped the mock-up block into the truck... not so easy to do with one person and no engine crane availibe. But i managed with a little grunt work. The motor mounts i used were the stock 4.0L rubber mounts with the dowls ground off. The brackets on the engine were the stock brackets from a 93 thunderbird. The right side lined up without any trouble at all.
The left side i had to slot the hole in the bracket because the stud i the rubber mount was not in the right spot. I just slotted the hole last night at work, so today im going to see how well its all going to line up. Then comes putting on the heads and finding out what headers are going to work. The options ive got to work with are the MustangII 302 headers, and the 93 thunderbird H.O stcck headers. Either one I use i can modify to make it work, i didn't buy either, so i wont feel bad if i need to cut or bend them a little. But so far everythings going just nicely.
The only prblems i see with the motor mounts is that the engine is located a little too far foward, im probably going to end up making a couple plates to move it back a bit. We will see how things go.
