    the opti spark sucks in water or mud by the way. all the lt1 drive stuff on the front is left to right swaped. like the p/s pump and stuff. need to make lines for this. but basicly simple swap. if your fuel tank is setup for tbi pump then simple pump swap also.

    i did this swap...twice youll need to cut the pass side frame rail to make way for the pulley. (1le ac delete) its aboot a 1 1/2" wide by 3/4" into the top of the rail.
    Also fuel sytem, i ran dual 16 gallon cells and an inline pump/ filter. (with a return) Youll also need an electric fan.
    Heater hoses need an adapter from 5/8" to 3/4" (for one of the hoses) also a throttle body bypass is easy to do.

    Youll need to run the coolant pipe from the back of the heads to either the heater hoses or if you have it aux port on the radiator. Of course 02 sensors, computer mounting.

    The power steering lines work (the stock lines from whatever car you took the motor out of. just need to make a few custom bends) with the oring type fitting so from the pump to the box your cool, then you just need to mount the resivoir and plumb the return line and the feedline (feed is rubber 5/8" hose) and return is the same as whats already in the truck.

    A new flywheel and starter is needed if using your current tranny. a 168 tooth and a regular ole' 350 starter (unless the flywheel works with your torque convertor, it didnt with my 400)

    If you have any more wuestions feel free to ask, or pm me so i see it and dont forget aboot this thread...

    alright.
    so from what it looks like what i need is the 1le ac delete pulley, fuel injection pump and tank.
    is there anyway i can re arrange the accessories to fit like my stock ones do? the a/c and heater hoses dont matter its gonna go into an offroad only truck.
    also im probably gonna sell teh supercharger to try to make some money and save some parts.
    i wonder if the flywheel will bolt up to a t350 torque converter hmmm?
