Mike, first of all, I applaud your effort. If folks didn't ask 'what if', we'd still be riding horses. Go for it. I've thought of the same kinds of things myself.

A few questions/comments.

1- What happens in the tranny when you rotate the pan so it's no longer level? Will there be any issues with fluid pickup etc? Manny is your go-to source for questions about that.

2- I have a 6.0 in my '07 GMC Serria pickup. It has a 3.70 final drive and it will indeed make a lot of power but it makes it at 4000-6000+ RPM. With a 425 and 3.70 final drive, you're still going to be at 3000 rpm at 60mph and I don't know if that is the sweet spot for LS torque.

3- Hal StClair did a masterful job installing a diesel with motor tranny in his Royale. What he did was use the entire tranny and front wheel drive system from a 1 ton 4wd. Not anywhere like a kit that you are thinking about but he has a modern overdrive 5 speed tranny and a final drive that fits the motor. The RWD portion is blocked off at the tranny. The 425 is the major problem with updating the GMC imo.

4- What about rotating the MOTOR instead of the tranny? The fuel injection shouldn't care but you'd probably have to modify the oil pickup and still modify the oil pan.

5- From a kit standpoint, raising the hatch is much more viable than modifying the step for most folks.

Just a few thoughts from another fabricator.

Kerry Pinkerton - North Alabama Had 5 over the years. Currently have a '06 Fleetwood Discovery 39L
