Hey Bud,
Re-post this question in the Small Ponies Forum and you'll probably get some get info. They are the six and four cylinder gurus. You didn't say whether it was a manual or an auto, but you definitely want to step up your gears to like 3:73's. Pulleys would be cheap as well. Then there's always the giggle gas...
Don't be so down on your six, any car can be made fast. Just don't drive like you're the fastest thing out there and you'll get respect for what you have
Good luck
Brett
