On t he cheap I'd call summit and grab the smaller 455 cam and a T-chain set. I'd also run some dual exhaust and up the rear gear to 3.23. As for intake I'd try and find a DP4B or Holley SD. I'd run a 4 hole 1/2" spacer and a small holley or 625 carter. That should wake it up plenty and it won't hurt your mpg...if that's a concern.
