I pick-up up a takeout engine and tranny from a 2006 Mustang GT. For those who are not familiar, it is an all aluminum 4.6 with the 3-valve head. Puts out around 320hp in stock form but I also picked up a set of stage two ported heads and stage II comp cams with upgraded valve springs. Once together and tuned should be able to lay down around 380rwhp and spin it out to 7000rpm. Not sure if I will keep the TR3650 or find a TKO500/T56, really it will be a budget decision for later down the road.
