    The whipple will last forever under tough conditions. I would slap a whipple on it just because of the low end torque and it will last. There are whipple kits all over ebay for the 454 you just need a little time. They are rebuildable also.
    An sts turbo might not be bad either, but the oil issue is what I would not like.
