I just went thru a wresting match with TTI's on a 440 in a 70 Charger. The car has been hit in the front in it's previous life as indicated by the wrinkles in the inner fenders back by the hood hinges. Eventually I got things to fit. The right side engine mount has a 1/8 shim under it & it now has a stock trans mount...

Try this: Remove the thru-bolts for the engine mounts and carefully jack up the engine on each side and set it back into the k frame. After a lot of head scratching I tried it and it helped.
Be sure if you have an aftermarket trans mount that it is not taller than the stock one.
