I am about to buy a 5.4 out of a Shelby after I change the connecting rods out I'm going to swap it out with the 4.6 . while I am doing this task I would like to also transmission swap. the tremec 6060 (6 speed) in but they are very expensive and I found a very good deal on a tremec 6070 (7 speed) out of a wrecked vette and Im wondering would it fit fine in my 06 gt and 5.4 fine with just a bell housing change?
