    Well Im looking into some options for the GFs 1990 2500 Chevy Z71. Its her baby and her project, however I have to be the brains of the drivetrain. Looking into two big options, Engine swap to a Vortec 350 with Holley throttle body OR swap to a 6.2 diesel. I like the ideal of a diesel, but only a turbo diesel.

    SO here it goes:

    option 1: Engine swap to a 6.2 diesel w/auto trans, and add a turbo. STart with a core and rebuild the diesel for more power and torque. custom plumbing a turbo w/intercooler at 6-10 PSI.

    option 2: emgine swap to a turbo 6.5.

    How difficult would this be? Looking for some UMPHH to turn 36" tires.

    if you have the money to go big then go BIG! put a 6.6L in that truck and really make her move. if you have the money. you have to change out all the computers and trannys and such.

    Actually if we leave it gasoline Id prefer to stick to the 350, OR build a 383 with Vortec heads and a Jet chip. I much prefer multi point fuel injection over the TBI (Hence I myself prefer Ford 5.0s and 5.8s.) but Im just not spending $1600 for a MPFI system. I will make do with a 670 Holley TBI.

    LS376/480 HP 6.2L CrateEngine with HotCam 19244549 Description 19244549 old #19213229 LS376/480 HP 6.2L GMPP CrateEngine HotCam.
    LS3 + Hot Cam = Loads of Fun
    480 HP @ 5750 RPM, 475 lb-ft Torque @ 4500 RPM The hot new small-block V-8 in the GM lineup is the hyper-aggressive LS3. It offers a high-reving 376-cid combination that represents generations of small-block V-8 development and engineering.
    Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this, the engineers at GM Performance Parts offer you the LS376/480—an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!
    The LS376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port L92 units that have been upgraded with high-reving, hollow-stem valves. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft.
    The GM Performance Parts engineers picked the LS Hot Cam (P/N 88958733) to take the LS3 to the next level. This cam specs out with .525" intake and exhaust valve lift. Duration (@ .050") is 219° intake and 228° exhaust, which allows for a dramatic increase in power. The engine will idle and cruise just like an LS3, but the power increase is there whenever you need it.
    14" automatic flex plate included. [​IMG]

    If you are thinking diesel skip the 6.2/6.5.. Find a duramax or a cummins. as an owner of both a 6.5 and a duramax, I can tell you the duramax is years ahead of the 6.5. no comparison...

    if you live in a nice place to find wrecked trucks in a salvage yard you could probably pick one up cheap. find a wrecked one that has no oil leaking and stuff like that. but between the 6.2 and 6.5 i would go with 6.5. fits that year of truck.

    Pardon my ignorace but was the 6.5 turbo?

    At this point im kicking around ideas. RIght now the truck has a 2in body lift and sits on 32"s. However in the future we are looking into a 6in suspention lift and 36"s. The stock 350 has anough low end grunt, but is definitely lacking in the high end dept. Im afaid the the 36"s would weaken the only thing it seems to have, low end. I had considered building a 3823 stroker with Vortec heads as a replacement. Hoping to gain more power. But then the idea of Diesel crossed my mind. I have never seen a turbo diesel shy of power.
