for some reason it seems to be that the new body style 07's are alot faster then the 99-07 classic body styles? can somebody shed some light on me and educate me cause im looking to get an 07 within the next few months and do full bolt ons and h/c.

 

You wont need to do heads unless you want to get them ported. the main difference for the new body style is they come with 243's. they are also heavier, but the added horsepower makes up for it

 

get 4.11's they are a pig with out them

 

dads got a 08 reg cab 5.3 and 3.73's and its quick as ****. I think it would outrun me by alittle
