99 Denali

[Snowbound]

Included injectors are Delphi EV6 24lbs/hr. @ 43.5psi. units with USCAR connectors. They work out to about 27lbs/hr. at this fuel pressures of about 53psi. These connectors are used on some Ford SVT models and the LS2 and LS7 engines. They are high impedance (~14ohm) and the same physical dimensions from o-ring to o-ring as standard Bosch type injectors. Anything blown or having more cubic inches will want more of an upgrade in flow than the OEM Marine injectors can provide. (The whole point of this swap is that be able to put any size injectors in there you want!)
Standard EV1 injectors will also fit the rails and a harness must be made anyway. Connectors for the "oval" USCAR connectors are available.

The Marine Intake Manifold has no provision for a thermostat bypass like the stock manifold.

The manifold casting does have the appropriate internal structure and enough metal to drill through. Some creative use of cold weld or epoxy is required inside to make sure the tapped hole is a sealed passageway through and into the internal structure.

There is no hole for the temp sensor but the boss is there. That needs to be drilled and tapped as well.

Pics won't load. I'll put them up when I can.

As far as axle, I'm going with a 14bolt semi floater 9.5" ring gear because it's a 6 lug and it already has 4.56 gears and a posi.

I'm not sure why I cannot load pics. They will not upload for some reason. I'll have to work on that.

Anyway, I got the axle all cleaned up and I'm sourcing disk brake conversion for it. I heard I can steal rear disks and all associated brackets off like a 04 Tahoe with a 10 bolt but I need a 60mm spacer to get caliper bracket in the correct location. I called a company that makes 20mm spacers for $50 and they quoted me $200 to make them in 60mm. I said forget it, I'll cut flange off axle and move it outward 3/4" before spending $200 just for a spacer. More to come on that.

I have a matching front axle from my 97 that also has the 4.56 gear set. That axle has the thermal actuator and my Denali has the motor actuator. Dorman sells a harness for this type of conversion (part# 600-600)but the proper wiring is already there, I just need the slug/spacer for the actuator. I have an email out to Dorman about buying just the spacer from them. The kit is only like $35 so if I have to buy the kit I will. Still waiting to hear back from them. I'm gonna rebuild the front axle, it needs to be resealed at the very least but I'll go ahead and do the bearings while I'm at it.

Might be easier and cheaper in the long run to spend the $200 for the 60 mm spacer. Instead of dealing with all the associated be that entails cutting, welding etc.

great build

What I don't understand is if they sell 20mm spacers for $50, and they want $200 for a 60mm spacer, why wouldn't I just but 3 pairs of the 20mm and stack them for $150? I couldn't wrap my brain around that.
It'll literally take me 20 minutes to cut off the backing plate flanges and clean the axle tubes for welding. I'll have to mock up the brakes to get the rotor sitting in the middle of the caliper and then tack weld before disassembly and final welding. I'm thinking at least this way I can clock the caliper anywhere I need it so I don't have to get fancy with making a bracket for the parking brake and to get around any possible interference I may encounter. All I need is to grab the backing plates, brackets, parking brake cables and calipers to use as cores from junkyard, all the maintenance parts will be going on new. Also I need proportioning valve for rear disk. I'll prob grab this stuff this coming week and order parts to rebuild the front axle. Still no word from Dorman, prob not until Monday.

This morning I decided I'm tired of adding air to the left rear and right front tires, I have a slow leak, no puncture anywhere it's coming from the valve stems. These tires are pretty worn, they've been on here since '10 and 22k miles. I've been rotating but having a little power with applied force to the skinny pedal it doesn't take long to burn thru a set of rubbers. Besides that, they weren't new when I put them on and they're E rated which I don't need on this rig. They came off another truck I had but they weren't even 1/4 worn. They are Bridgestone Dueler A/T Revo tires and I loved these tires so much that they are on my Dmax and I just recently put the Duelers on the Equinox, but the H/L series.



Anyway, I was going to Firestone to get a new set but had to stop by Sears to order a new horizontal band saw and I noticed they had a sale on tires. I picked up a set of Cooper Discoverer AT3 tires. Got one free and free financing on my Sears card, couldn't pass it up.



So I came home and put the truck up on stands. Before I put tires on anything I always check the front end so there's no surprises during alignment. All the parts on front are new, I say new but they were put on in '10 when I bought truck only 22k miles since then. I found slight play in passenger outer tie rod and drivers side inner. Everything else was good until I got to the passenger side upper ball joint. It's loose which explains why I had a shimmy at 76mph, I thought it was the tires. So now I'm in the process of tearing the front end apart. I'll swap the tires and be able to get my alignment next week. I know I need front shocks, rear was just changed 2 weeks ago when I did brake line and master, but I'm contemplating something else for front suspension. Updates coming later. Not sure if I can warranty these AC Delco parts thru Rockauto or if I'll just run and grab some Moog replacements. Don't think I wanna wait.

You'll love those tires I have them on my 03 Silverado

Good to know. Thanks. I read some reviews while I was looking at tires and these seemed to be a good tire at a reasonable price. I don't really need A/T tires for this but I do run this truck up north for snowmobiling. My sleds are up there already but it's not uncommon to throw them on trailer and head another 85 miles to the U.P. Nothing worse than no traction in snow, hoping these will do the job.

I really like Cooper tires. Had them on my stock 03 rims. Cooper Discoverer HT's. Great tires.

Well, if your gonna dive in, might as well make it a belly flop. I ordered the entire front end again minus CV's and hub bearings. Probably get some POR slapped on here too. Looking bad.





All this might be warranty. Gonna contact Rockauto on Monday but I have to find my paperwork in my file. Can't go back that far on their site. Brakes are about half way, I'll hold off on that. Time to rip apart other side. Parts will be here Wednesday, tires will be on rims Tuesday and alignment on Thursday hopefully. I'm leaving Friday night to head north to get sleds ready for season and then I have Toys for Totts ride Sunday morning and I still need to do something about rear brakes dragging on bike. No rest for me this week.
