Hehehe. No I don't know the true story behind it either, was hoping someone else knew. Thank you for your input. here is what I was thinking about for starters:

Flowmaster Series 40 SiDo (2 1/2" outs prolly)
Volant Cold Air Intake Kit (don't know if it's worth the $$ or not)
PowerAid TB Spacer
Maybe a chip of some sort.

I never thought about a shift kit. I need to look into it. Do you think those plugs/wires really enhanced the spark?

Thanks for the congrats. No, I am sorry. I'm not the one selling the boat. My fiance would shoot me if i had one and was tryin to sell it. She loves em.
