2007 Yukon Denali Build (This got outta hand really quick...)

ZL1 Heat Exchanger fits like it was meant to come like that from the factory... Will be securing it in the morning and running the plumbing. Should have this beast started Monday/Tuesday.

Decided to mount the heat exchanger with 4x plastic plugs. Worked out pretty good, solid enough for me. Will be mounting the Tru-cool behind it. All the electrical on the motor is hooked up, just need one 45 silicon elbow to finish the intake. Was able to fab up a 4" aluminum intake out of 2X 45 degree bends I had laying around. Should work out perfect and retain the factory air box location.

Had some bad filler rod so I will probably cut this up and redo the weld... Or just paint it black, not sure yet.

Looking good. Video if first startup with the tubes and charger

Coming soon for sure... Waiting on a damn 45 degree silicon elbow for the intake. Everything will be in Wed/Thurs. Should be driving it and testing/tuning all day Friday and weekend.

Lots of progress today... Ready to get this beast started tomorrow. Oil changed and all fluids filled, still have to do two basic hose runs for the heat exchanger but it's ready to go. Brakes were bled today and pedal is rock hard. Got a basic tune setup and she should fire as soon as the heat exchanger and pump are plumbed & wired up tomorrow. I got my silicon 45 degree elbow today so intake will be done and I will update with pictures of that.

Not sure if I mentioned earlier, but I had some coil pack clearance issues with my fuel rail and had to modify them. I will eventually make a custom bracket but should have gone with a CTS V rail that sits up 1" taller and it wouldn't have been a problem. It wasted a lot of my time.

Cleaned up some of the wiring and vacuum lines. Lots of crap here lol... Defiantly a 10lb of crap in a 5lb bucket situation. I will make this as pretty as possible and redo wiring and lines if needed once I know it runs well... I also plan to clean the engine bay as soon as its running. Already got my cleaning supplies lol.

Catch can was also put on today. Like I said, pretty much ready to go for starting it tomorrow... VERY EXCITING!!!

Even got EVAP Solenoid working

I can't wait to hear that baby run!! Looking good.

Made some changes to the intake today... Unfortunately didn't get to start it but it's ready. Because I rebuild the transmission and replaced the TECM I need someone to reprogram it for my VIN. I was under the impression HP Tuners had the ability to do that but I was wrong. I've got a guy coming over at 10am tomorrow and flashing it for me so we can get this ***** running.

Intake changes... Has some major issues welding this material. I got it from a surplus aerospace supplier but it was contaminated at **** and welded like crap. We cut up the intake 3 times to get it right. Looks much better now... IAT2 wire need to be connected, thats about it before firing it up.

***Not able to upload pictures right now for some reason... The Forum might be having issues. Will update when I can

Looking forward to see how this thing runs. Great progress. I wish I could have mine down for weeks at a time but since it's my DD the most time I've ever had it down for was 4 days when I had problems installing the Whipple. It's always in my mind that I need to plan for the worst and hope for the best lol. I can't locate a shop that wants to install the cam without pulling the heads (and thus the Whipple) so it looks like I'll do that myself too. It will have to be done in 2 days so I'm planning the best I can! (I do realize it shouldn't take more than a day but I'm not good at this like I was when I was young). So glad to see you've come to the point of starting this beast up after so much hard work. Sometimes it's hard to comprehend why we do this until those moments when we mash the throttle and fly.
