EFI all the way. Carbs have issues with fuel starvation, and altitude adjustment. EFI does all that for you.
All-Pro is just as good as Marlin's parts. They both provide high quality parts for those who want them.
And for running 38's, just get a 5" lift and get friendly, really friendly with the sawzall!!
You could do it with a 4" and some inner fender/cab massage with a welder. Best thing to do, is keep the center of gravity as low as possible.
