I started test fitting the 350 this weekend. I have AA motor mounts and have them adjusted to the proper width now. I have had to do some slight relocation/bending to get the block back far enough. I bent the brake lines where they come off the firwall on the passenger side back to the firewall and had to remove and relocate the little bracket that holds the clutch line. The real question is how low/high did you mount your motor (how much of the AA mounting bracket sticks up above the frame, if any), and at what angle front to rear did you mount your engine? I know that the answer to this will vary somewhat with the transmission that is used. I am using a NV4500 and it has a tall tower that will need all of the 2" body lift I have already installed. Lastly are there any other gremlins I should know about that you ran into.
