I have handled all 5m, 6m and the 7m motors. The taco motor is a waste of your time and I woulda never considered it, the 7M is way too heavy and only puts out like 5 more ponies with the torque also being roughly the same as the 6M, the 7M also is no good for boost apps. because of the smaller valves tend to burn. The 6M-GE is the motor to use its the same as the 5M only a its 3.0 not 2.8. All you have to do is open the motor mount holes, relocate either the fuel tank or the exhaust routing and move the fans to the front you have a straight axle so you won't need an oil pan swap or custom.
