    after my list of n/a mods, i have come to the conclusion to topswap.
    would it be better to buy a kit from zzp, or should i buy a used l67 and swap everthing over.
    also, what can i do to help my transmission. shiftkit? hardened shaft (trans is from 97 and i know it will probably be gone soon)
    i plan on nothing special, maybe 3.6 pully w/supporting mods.
    97 grand prix.

    Like I've said before...

    You'll need a new transmission because that vacuum powered 4T60E junk won't hold up to anything.

    It would be more cost effective to just buy a '99+ car.
