Here is what I have been doing with my free time since I picked this beast up around thanksgiving. I picked up this 6.0L 4L80e locally on ebay for $1,136. One of the headers was damaged from the accident the truck was in. I was able to find a replacement set of 317 heads on ebay, that have a been completely overhauled, New LS2 Valves, Springs, Seals, and has been surfaced for $375. I was also able to find a Magnacharger, on ebay, MP112 intercooled, very lightly used for only $2,800. I will be installing a cam shaft I also found on ebay that had 1000 miles on it for $190, Lingenfelter LS1-GT2-5 222/222 .566/.566 w 1.7 rocker 112 CL. I went to summitracing.com and ordered pretty much everything I need including, all tensioners, 25% underdriven harmonic damper, idler pulley, ARP head bolts, damper bolt and other bolts.
The block is going to take a trip to a local engine shop just to hone the Cylinder walls to get rid of some very mild corrosion from moister that leaked in from the crack in the header. Then I will be hitting it with the gloss black engine enamel, and then she goes back together.
Still plenty to do but that is the progress so far, Any comments would be appreciated, I don't want to miss anything...

 

 

 

man thats going to be a sweet setup,but i dont know if the underdrive crank is going to help with the blower.

 

Oh yeah? I don't care so much if it doesn't add that much HP, the motor just needed a new damper. It won't hurt will it?

 

if anything, you want to put on an overdrive pulley.

 

Good to know, this is why I listed the stuff I was doing. I'll just return the underdriven one. I'm new to this type of stuff.

 

the underdrive pulley will slow down the blower, which means less boost. i am running a stock pulley (pinned) and making over 600HP.

 

I hope that cylinder cleans up... I was looking at those heads on Ebay. Seems like a great deal for a budget set up... You could easly spend $300 haveing a good set of heads cleaned and serviced with the Z06 springs at a machine shop assuming you had a good pair of cores. You obviously had one bad one so I think your 1 up there...

 

Yup I do have one extra good 317 with 68k on it that looks to be in perfect condition if someone needs one, pm me to discuss price. I hit the cylinder wall with a little scotch bright pad and it looks to be ok. Very mild surface crap. I'm sure a machine shop can hone it out quite easily.
I do have a question regarding that though. If they need to take a few thousands out of that cylinder to clean it up, then they should match the rest of the cylinders by taking the same amount out of them right? Can anyone recommend a brand of forged pistons. They don't have to be a crazy racing set, just stronger then stockers as this truck will not see much if any track use.
