I have a 98 c1500 reg cab, swb with a 4.3L v6 and almost 200,000 miles on it. I have a 6 month old jasper 4L60E in it. Im wanting a V8 with ball but a street leagal dependable vehicle. Im located (well in Afgahnistan till the first of the year) near Va Beach, Virginia and no one will call me back or answer an email. I want atleast 400+ to the wheels. Im thinkin a built 5.3L from my year model, or a 6.0 from a newer truck, or a LS3 from a G*. What do u think? Can any1 give me advise or point me to a mechanic cus I want it done right. Thank you

 

Whats your budget? A big NA 6.0 or a blown 5.3 could do what you want. I would do the blown 6.0 if it was my choice.

Just to add, since your truck is an older body style, none of the newer engines would be a direct fit and would require changing just about everything. It may be easier to sell your truck and buy a newer one with a 5.3 already...
