I think this is the part where most people go wrong. Everyones always worried about HP HP HP. If you can get you HP to stick then you are not going to be fast at all. If you want to do things right, build your drive terrain up, then suspension, then lastly build up the engine. Start by picking up a nice auburn/detrioit/or Ford Racing Trac-loc Diff., then a set of 31 Spline axles. Either moser/strange/Superior is a nice set also, gear, then a nice diff. cover and some royal purple fluids. This is a great combination and theres nothing better in the world than not having to worry about having in axle snap while you dump the clutch on your 28in slicks. lol. Like Darrell said dont let money put you into a crunch, dont ever buy the easy way out.
