Just found this. Your K10 has always been one of my favorites, figured I'd hang around and watch what you do here.
How's the 454 coming?
Thanks dude! Well, the 454 SuperSportside is coming along……..slow as usual but its coming. Hope to be doing burnouts by Valentines Day. Not much has happened with anything for the K5 other than I installed one axle U-joint
Kinda derailing my own K5 thread but here is the progression of the SuperSportside…
TBI teardown commencing
After power washing 7 years of road grime off
New bits that had to be installed to run the MPFI. A 4x reluctor wheel and a fresh timing cover with a crank sensor provision
And a brand new L29 Throttle Body.
L29 intake all cleaned up and ready to fly
Intake on with fresh injectors and new injector harness
Pulled the old timing cover off to install the 4x reluctor and found the nylon timing chain as loose as a $2 whore. This discovery cost almost over 3 weeks given it was right as we were going to the Christmas holiday. I ordered a really nice new Howard's L29 timing chain which was not correct as my 454 does not have a roller cam. Ordered a Gen V double roller and found that a double roller wouldn’t clear the reluctor wheel. Ordered a Gen V single row chain and it worked but that caused a lot of delay and hair pulling
Finally got the front together after a new L29 balancer appeared in the mail. The L29 balancer has a shorter snout to clear the reluctor as well.
Converted the left-hand fender from a 1993 spec to a 96-00 in order to mount the black box ECM in its OEM location (where the 93 windshield washer reservoir used to live) and add the L29 EVAP can in its correct spot. This turned out to be quite the project as the washer bottle had to be upgraded and relocated to the 90-00 spot as well as the horn to the front side of the radiator support. The horn and washer pump needed some rewiring to reach their new homes to boot
Then the Howell harness arrived so then it was time to start pruning the 1993 chassis harness of all of its prior TBI lifelines and figure out how to merge them. In true Howell fashion, several leads were too short, in the wrong location or had the wrong gender or generation of connector, which I am still sorting out as we speak but the engine harness is in the truck now. So frustrating
This is the 1993 chassis harness after pruning. I tell ya, this truck required a lot more careful pruning and wiring over the K10 and Suburban by 1000% as there is so much more integration between the chassis harness and engine harness on GMT400 trucks. Plus the fact, I want ABS and everything else to work as it was before.
@ZooMad75 came and hung out last Saturday and Sunday double checking my chassis wiring plan as this harness will be a mofo to pull back out to address errors if any are made now. We came up with solid plans for a few circuits I wasn’t sure which way to go. VSS and TCC for example. Howell has their own lead to feed the black box but the 1993 ABS wants gets it signal from the DRAC. The other thing that is new to me is dealing with an auto trans and sorting out the torque converter clutch. Given the fact this truck was originally a 5 speed manual made it easier….or more difficult....Haven’t decided yet
Thank gawd for Zoomad having access to these OEM wiring diagrams from the dealership. This makes things much easier
This is how she sits at the moment. Howell engine harness is in and I'm process of wrapping up the 1993 chassis harness then throw it in the engine bay and merge a few circuits together
oh, and the buyer for the yellow 68 GMC petered out. He ran into family health issues so the truck goes back in the market again
