Silveradoss L92 budget build
I am going thru another set of mods. I wanted to make a post to help others and show off a bit J I am going to have three sections.
I:The parts
II: The install
III: The results
This post people can follow along and learn as I do my first head swap and my second cam. A key in this was budget, I wanted to run a turbo but w/o a job I was scraping by. I got a great deal on the intake and some misc suff so I decided to give it a try. Another reason for the super long post is how I found so little info in this upgrade and wanted to share.
I: The parts
L92 assembled heads. I am using the stock valves and not pushing the lift too high to put unneeded stress on the valves.
Comp 918 Springs (new version): I got these as replacements for the blue striped ones I had. So I decided to use them.
L92 Truck intake/90mm Throttle body: This was one of the cheap parts and just comparing them I know its better than stock.
L92 Fuel rails: These are returnless rails so I had to mod them a little.
Marine 42lbs injectors: I am using these so I cont have to mod the fuel rail and can still have the added fuel I will need. I swapped the o-rings from the L92 truck injectors. This also keeps me from changing the injector ends, I don't want any electrical gremlins.
Vette fuel Filter/Regulator: this was added so I can run the returnless rails. I did not want to cut up my stock fuel lines and AN fittings are not cheap. I hope this way I can just get some programming changes to compensate for the fuel being regulated by the atmosphere instead of by vacuum. Here you can see how I mounted it to the rail and had to bend the supply up a bit.
Stock GEN IV rocker arms: While I could have used ½ of my stock ones I have the complete set off the L92 heads.
Stock 6.2/6.0 GM MLS head gaskets: these are a nice looking gasket and the cost fit the budget.
Stock GM TTY head bolts: I could not see spending the extra $$ for ARP studs, I hope I wont have to change these heads again
Stock crank bolt: This is a TTY bolt so I just got a new one
X-link: this allows me to use the new throttle body and its plug and play. Very nice piece and I can keep away from cutting wires. Here you can see the x-link mounted.
Here is my 2/3 of my son's and my cam selections...
Livernois Stage I cam: 224/230 .581/.590 114 LSA. I chose this cam after a lot of searching with very little help. L92 cams are top secret and people want to sell their grinds and with every search I found more bs. Livernois is local to me and I figured I could talk to some one and it might make me feel better about going that route. Worst case is I pull it and try a third cam. A lot of my reading said that smaller cams made similar power with better drivability. This by far was my hardest decision and I still am not completely sold but so few people are doing L92's on heavy AWD trucks so in some ways I hope to break some new ground or at least add some info to the discussion.
OBX LT headers: I have wanted headers for a while, and these are SS which IMO makes them a great deal. After looking them over all I can say is they look top notch, the welds are perfect. I will live with the driver's side hump.
07 E fans: I got these with my other L92 parts and figured it would help with space, Again I have read some issues with surging and e-fans but I think I'll give them a shot other have them without issue.
Nelson Fan harness: Thanks to Cody (montanaSS) for getting me his, While I was going to make one I am not looking for electrical problems and hopefully this will go in easy.
II: The Install
Next week (waiting for the cam)

The Install:
I have done some wrenching in my days but not on my baby. I swapped the cam and have done some repair work on a lot of other cars/trucks. I was following the LS1howto.com directions but they are not too accurate for a truck.
New xlink bracket
Stock intake tube
The new intake tube which caused the relocation of the xlink
