I was curious to see what mods you all have done and what outcome you got. I have a 4.8 with bolt-ons, cam, and spray that has brought it alive pretty good but this summer I will be doing a complete rebuild and want to get some opinions on what would be the best mods?

 

hey what are you running with the current mods, and were do you want to be,( by that i mean power level) there is many different setups

 

I had a 4.8 ecsb runing 14.9 with just boltons. stock cam,stall,stock internals

 

if you are going with a rebuilt then might as well step up to a 6.0!!

 

With the truck as it sits, im at 345hp and 381 trq. This is with a shitty hypertech programmer and an a/f that drops off around 4000 rpms. Ultimately I want to be btween 400 and 450 to the wheels.

 

any quarter mile times??

 

never run it at the track, I'm honestly not too worried about track times (x-cab= TOO MUCH WEIGHT!) but a fun and fast weekend toy.

 

My 4.8 makes 540/560+ as it sits. YOu need a power additive to make any power with these little motors.

 

sorry to get off topic but what is the part # of the air filter you are using?

 

Good lord, what you got on that thing! And as far as the part # on my air filter, it was givin to me from a friend, but it's a k&n with a universal opening that I mated to my MAF and tb with a coupling sleeve. sorry man, no part # for ya though. I would go look at it but its in Georgia and I'm in Texas.
