Dyno sheet also posted

Goin w/ a Circle D conv. also

This will probably be all that I do to it before the turbo kit goes on. I daily drive it everywhere and still get 17-18 city and 21 hwy. I also haul a car/18ft trailer for goin to the track which brings mileage down to 15-16mpg. Let me know what you guys think on cam choice and if I forgot any info let me know

 

Noone?

 

Getting that good of mileage, I'd be afraid to change anything. My nearly stock 4.8 doesn't get what you do with an SUV.

 

My 08 yukon around town gets something like 10.5, grabted its mostly 2 miles of stop and go bs home to work to work to home but still!!!

 

I think the stg 4 truck cam is a good idea. Just my opinion

 

111 lsa is going to be a much more noticable lope..... I had the comp xr275hr 54-426-11 in my truck originally (granted i have a lq9 bored .030 over and rectangular port heads) and it had quite a bit of lope to it and made 345ish hp at the wheels..... But lacked bottom end, part of which may have at the time been the lack of stall speed and a trans i dont feel was what it was made out to be....

 

I figured not being that much bigger, hopefully mileage wouldnt suffer to much.

 

I have a spare trans here that Im building up w/ some good parts and a stall will be ordered. I know right w/ my cam it needs a stall too, it dont really start pullin till about 2k
