What to do with 800.00

[429mustang]

I'd put the $800 aside and save up for a supercharger. (turbo would be sweet, but seems a little more expensive/copmlicated, but would definitely be bayad). You could swap the auto for a Tremec, you'd probably get a good amount to put towards it selling the auto w/converter. I'm not sure if 4.10's would help you out too much, nitrous seems like a good route also, fairly cheap and isn't pushing your motor all the time like a blower, plus will give you more gains for the price than probably anything else.
