I have a friend who has a obs suburban with a 454 & a 4L80E. He went to put his truck in reverse yesterday & it wont engage. He said its like putting it in neutral. In drive in runs just fine. It has...

How much?

Well, the engine is on the stand & going to be torn apart soon. I have decided to go thru this motor & spend the extra $ & make it right since I will probably be keeping this truck for some time. For...

Well, ever since I took my FPR off & reinstalled & added a bottle of seafoam to it, there have been no issues for about 2000 miles. 500 of those were towing 2500 lbs & another 550 towing about...

Checked grounds this am. All good there. Im going to drive it more here today & see if it will still do it.

Fuel pump was ruled out the hard (expensive way). It was replaced 2 weeks ago along with a new filter ofcourse. These same issues also occured before then. I figured it was the pump cutting out every...

I was wondering the same thing. Currently my exhaust is stock with 3" duals back to the muffler. I replaced the muffler with a magnaflow dualed 3" in/ single 3" out ( I got it for free) & replaced...

Is it much beneficial to change out with the 160 stats? Mine never seems to go over 210 no matter how hard I work it. I remember hypertech use to advertise that with a 160 stat they produced more...

Whats weird is that the truck runs awesome most of the time, then this happens & it losses almost all its power. I did get a P300 (misfire) code but thats it. It might possibly be a tps as while this...

No. No SES light. Im thinking its something to do with my fuel pressure regulator. Yesterday I towed my trailer over 500 miles and when going up steep grades (7%) it would run awesome then just start...

Anybody???

My truck is in my sig and also has a diablosport predator tuner. Every once in awhile when I romp on it the truck acts like it is getting no fuel & does it for about 20-30 seconds then starts running...

Sorry to bring up an old thread, but figured I would try to get an idea of how far to go with this motor. I bought a complete 6.0 out of an 01. It even has all the accesories with ecu & wiring...

Awesome! Then I'll scratch heads off the list & use the stockers. I thought these old iron heads were junk. My engine has over 186k on it & its going to get a rebuild soon.

Sorry for the off topic question, but are stock LQ4 heads best if you plan on eventually going FI?

Right on. Thanks. Didnt know if the motor had to be lifted or not.

Did the motor have to come out to do the o ring? My 6.0 is having oil pressure issues. When cold it takes awhile to build pressure. Just wondering how much of a job im in for?

Hey. I know its been awhile, but you still got that flex a lite?

Thanks a lot!!

Thanks a lot show & go. Thats what I was looking for. Since my oil pump is getting tired & my rig has almost 180k now, I think im picking up that 6.0 with around 100k for $600 & find a set of...

So many damn decisions! LOL. I was debating on selling the rig & getting a diesel, but if I can get some hp out of this truck & maybe a couple more mpg's I wont mind keeping it. Just have to do this...

Thanks

What are the 243's/799s off of?

So anybody run this setup here? I tried searching, but no luck. Im going to be picking up that motor within a couple weeks & want to get everything in order as quick as I can. If I get those 5.3...

That may be doable. Anything else needed on this swap that you guys can think of? Cam? TC? tuning? What kind of power could I expect out of it?
