    hey guys, i thought i posted this already but i guess the post didn't go thru, i'll have to bitch at the provider again.

    Well, the 4.8L is out and the 6.0L with 224/224, 114 cam is in. The truck runs great. There is more noise coming from the engine and it's a little louder as far as the valvetrain , but that is normal. Kind of like a sewing machine running.haha

    The truck has 20's on it, so that's not helping, but it's no slouch, it does have 4.10's. It will smoke that single tire forever, lol,
    It really needs a posi and a built trans, it falls on it's face after it shifts so bad, that is slows down enuff to shift back into 1st. I want to save the trans for a while that's what I haven't tuned that out.

    Speaking of tuning, you can't go to a 6.0L from a 4.8 without tuning, no way, the truck ran like shit, now it has a very slight shake from the cam, you hardly notice the cam.

    The truck really comes alive on the highway, it really needs a stall also.

    I definitely recommend the swap to anyone wanting more power.

    btw, it was an LQ9 6.0L, cam, and slightly Nelson polished/ported heads.

    I'm sure it's making over 400hp, we'll get it dynoed soon.


    later,

    I'll try and get some vids and pics, it looks like a stock engine under their, you'd never know it wasnt'a 4.8L.

    He still has the stock manifolds and exhaust. I'm going to build him a nice setup, here's what it will be:

    TOG Headers, 2.5" y-pips, coming into a 3" single, then a Magnaflow catback with the two oval tips in the stock location.
    He did mention that he wouldn't mind having dual exhaust, one on each side in front of the read tire.

    I'll look into the roller rockers, it'd be nice to quiet it down a bit,

    later,

    Sweet! About time that came together. Peg leg burnouts are no good. How many miles on that trans?

    Full exhaust will make a huge difference with that cam too!

    About 50K now are on trans/truck.

    Ya, exhaust is going to help a ton, that is after the rebuild.

    OH man, this is EXACTLY what I want to do to my 01. I installed the Eaton a couple of weekends ago. I would love to see what numbers he is putting down. I would put the 6.0 with TOG headers, magnaflow mufflers (from everything I have read about them), a cam and slap on some 18x8.5 or 9.5s to get it to the ground. With that, I was hoping for 350+ on the ground! I am looking forward to that dyno run sheet!

    I would like that exit in front of the rear tire too, with this tip!
