WHAT WOULD BE THE OUT COME OF THIS RACE 03 RCSB 4.8 AND A 00 RCSB 5.3 JUST CURIOUS

 

depends usually I would say a 5.3 but mileage and how the truck performs can very. what does the 5.3 have done to it since I am guessing the 4.8 is yours with addons in sig.

 

Stock Versus Stock. I Have Tried To Run A Few But They Never Seem To Take The Bait.

 

Good luck, like you I also own a RC/SB Sierra with the 4.8L(Hypertech/K&N FIPK III). I also have a 03 Yukon with the 5.3L(stock) and I can really feel the diffrence. What drop kit do you have in your truck? Any pics? Im thinking of dropping mine 3/4 with belltech kit. Well laters, The Bandit-Z

 

Gotta think the 5.3 would pull the 4.8 out of the hole and hold it. Would not be a total walk but that extra 40ft/lbs of torque would be the deal breaker.

 

The Bandit. Right Now I Have A 3/4 Drop But I Want To Go Lower.don't Have Any Pics Of Her Yet But When I Do I Will Post.

 

i raced a '01 5.3 single cab stepside vs a '03 4.8 single cab stepside and we were even till about 65 when he started pulling away
