I wanted to see wat u guys think, I have 07 nnbs single cab silverado 5.3 truck is tuned, cai, long tube header, 3 1/2" exhaust pipe, mild shift kit, 2800 stall, 3" lift, 33" mud tires my goal is to be running in the mid 13s what other mods do u guys recommend. Any advice is welcome

 

if you want to run mid 13s with the 33s your going to need some gears. i would go with 4.56s. i would start there. then start looking into cams. are you set on sticking with a 2800 stall converter?

 

nitrous kit lol?

Mayb goin wit a 3400-3600 stall

 

Gears are your best friend with that tall of tire. Next step is a blower or more displacement. It's a lifted 4x it wont ever be a dragster without trashing that little 4L60E.

 

True, but evrything is possible. Yea gears n cam r next. Wat size of gears? 4.56 seem a little to big but let me know wat u guys think

 

I am running 411 with 33's and it is a good set up. previously I ran 456 with 35's and 488 with 37's.

 

33s are heavy so from a performance stand point 4.56s would be perfect. dlt76028 runs 33s with 4.56s and loves it. plus if your truck has 3.73s right now, 4.10 is not much of a jump at all.

 

What bout rpms on highway with 4.56

 

Just got my cam 224/224 .581/.581 lsa 112
