Cool! Man you got the whole thing harness and all! About time your truck weighs more like a truck and not a car!! J/K I figured that was what you had in mind when you were headed for Hi-Way Auto.

Allen, I don't know if you have a 255 lph walbro pump in there already or not but if you don't, you might seriously consider one since you've already proven a lean condition at high rpm. You might also consider going to a flow thru fuel rail system such as those by aeromotive. The one line fuel rails are notorious for leaning out an engine during performance mode since they are designed to feed fuel to the engine as a secondary requirement. Cooler fuel is also a benefit with a flow-thru fuel rail system, too. As you know, cooler/denser fuel makes more HP and that's the name of the game.

Allen has the Walbro 255 pump and the truck intake which has the flow thru fuel system. I think one of the injectors he had was just not flowing like it should.

A quick question for Allen.....Is the rear crankshaft flange the same on the 6.0L the same as our's on the LS1 5.7s? I thought I heard they are a different length.

The crank is the same, if you buy a 6L with the flywheel on it, you'll notice they have a spacer behind the flywheel, that's the only difference.

Like the hitman said, 99-00 i think had a diff. crank.

later,

That is awesome Allen. If you don't mind me asking. How much did you pay for it?

My price won't be the same as when you call, it depends on how many they have on the shelf, how new, how many miles, etc.
I can tell you this, HI-Way Auto definitely takes care of their customers, besides the warranty and honest answers, I came out with a cool tshirt and several pens
Expect to pay anywhere from $1200-$2000, depending on year and miles.

I'll run the tranny , 60E, until it lets go, then I'll head back down to HiWay and get my HD trans.

see ya online,

allen

Hey Jeff, now we'll have a nice comparison on what is faster, an ls1 or 6.0L, all we'll need to do is disconnect the intake and open the exhaust, I'd like to compare them someday when we get some time.

Ya, the light weight is nice, but the squirrely rearend doesn't win races, hahaha

see ya soon buddy,
