There are a couple of ideas I liked:

For N/A, I would either do an all aluminum 600 cube Predator KB block or the Billet block Pro Stock 650 cube hemi one of the guys on here did that was just awesome.. Both would be super awesome, and I would do drag week on either with pump gas! Could you see my Cuda with a stock looking shacker hood and underneth, a 600 cube Predator motor on pump gas cruising around!

My other thought for a boosted application:

Pete Farbers NMCA truck with a procharged BAE6 or Predator motor....I like the prochargers do to the fact that they are a little smaller, but make huge hp...Heck a 6.1 Hemi in a light vehicle would be awesome.

Almost bought this truck, but its the year I lost my job and was unemployed for almost 7 months with a new house.
