Kinda new to this forum I have a 2007.5 ext cab 5.3 bolts ons/tune, on the side I have a yank 3000 stall PRC 243 stage 2.5 with supporting mods for a cam but what TSP cam would y'all recommend i was looking at the 224r and 228r not sure on the LSA would like to shift at 6200-6400 rpm, trans is stock 4l60e should I build it or swap 4l80e? And what kinda number do y'all think ill make I'm lookin for about 400whp that would be awesome! stock to the crank is 315hp.

 

You could do a shift kit and Corvette servo and let the 60e eat until it's gone then swap to an 80e. Are you looking at a low lift or high lift cam?

 

Im lookin for a high lift I had a stage 3 216/220 .600 110lsa but didn't seem like enough power looking for something bigger

 

What size tires are on it? Maybe a diff and a set of gears would be a good choice. Is it a daily driver or do you do any towing with it? Sorry for all the questions, I just know what a lot of the smarter guys here are going to ask to help you out better.

 

Stock Texas edition wheels with eagle LS2s if so what gears? I truck came stock with 3.42s, no towing with it, it is a daily driver but I don't care how it drives probably won't be a daily for long anyways
