I like your thinking...mainly because I want to do the same thing on my next build (unless I turbo this car). I was going to use 2 turbos and put them righ behind the cab. Much easier to fab up that way. That set-up isn't going to have a ton of power so your stock rear (unless it's an 8.25) should be ok. You might want to fab up a plate and run an adjustable pinion snubber. Later on you'd probably want to run a cal-trac system or something like that. That red truck is TIGHT!
