I wanna stick with the stock intake because I wanna run fuel injection, and shelling out $1000 for a Holley kit would bring on the suck...lol
Would there be a different t-case that would bolt up to the fullsize trans?

from what i have heard the intake will not only be tall but will interfere with the heater plenum box, because it is so wide especially if you have a/c
another solution is that i have run tbi's on what were originally mpfi, just take 2 opposing injector wires and run them to each of the injectors, i have several adaptor plates that will stick a gm tbi throttle body to a 4bbl manifold. i'd send you one if you went that route. then all you need to do is make sure the tps has the correct parameters (holley sells different tps's), then you take the nipple of the map sensor and clamp a hose around it that goes to a vacuum line. then if the donor truck ran a maf sensor all you need is a hat for a carb (the top of a gm tbi is 5 1/8" just like a carb) that you can run your intake duct to, spectre makes them for about $60.
last but not least a $35 manual fuel pressure regulator for the throttle body so that you can get the fuel pressure where it needs to be. the fuel curves/injector pulse will be the same because the same computer is running it. you will just have 2 really big injectors running it as opposed to 8 small ones. i have done this on obdII lt1 camaro's so i could put better flowing single plane carb intake manifolds on it. (i used a 1000cfm holley 4bbl throttle boddy though but the principles are the same) and the M.I.L. quit coming on once i adjusted the fuel pressure to where it needed to be.
just a thought.......
also the best plan is to take the entire engine, with the trans still married to the t-case, modify your cross member, and spend the $60 to have your driveshafts modified to fit the fullsize t-case
