    yes its expensive. couple grand for real kits. i would only have a shop do it cuz u have to machine the block for the extra length of the crankshaft and you have to bore the cylinders perfectly without screwin it up. one little slip up and you need a new block

    its an expensive project, but causes massive increase of hp

    someone correct me if im wrong on any of that
    i have a cam already (Comp Cams XTREME XE-R XER273HR - 224/230 - .581/.588 w 1.7 rocker - 114 LSA), if i do the heads then I'm done? What size motor is it with the cam?

    Would i still need a crankshaft? What about new pistons/rings? Would factory heads work if they're machined? I think i'll avoid it, it sounds like problems.

    The cam doesn't change the displacement of the motor.

    no sorry... cams dont increase displacement and neither to heads. only distance traveled by the piston and the diameter of the cylinder are put into factor with displacement... so u either need ur piston to travel farther (longer crankshaft) and/or bore your cylinders out (increase cylinder diameters).
    altho cam and heads will increase power a good amount also

    For 10K I'll sell you my 408 block with all callies billet internals and custom diamond pistons! For 5K you can get a C5R block, no internals though.

    That cam would be on the small side for a 382. To do a stroker, "yes", you need a stroker crank.
    2000 Z28 382/nitrous...sold and missed.
    2004 Z06 CE Z16...still looks stock.

    The 98's have slightly thinner cylinder walls.
    But you really don't want to bore any of them anything more than .010"
