1988 GMC C1500 - Z06 Package!

So... if you guys can't tell, the LS6 shortblock should be done at the machine shop, soon. So I'm working to assemble and clean all of the parts that go to this engine.

I originally found brand new LS6 coil covers, they were pictured with the correct black inserts, but apparently GM decided to quit doing that, what arrived was missing an important OEM detail. Which I happened to find aftermarket and applied to the new coil covers today.

My C5 Z06 did not have the black inserts. One of the first things I did was take the coil covers off.

Either they were replaced with later production 2015+ units, or the lettering was worn off, as all LS6 cars came with black letters.

LS6 specific valve covers procured, media blasted, painted, new grommet and pcv delete, NOS GM filler neck and Mobil 1 oil cap installed.

There's the black inserts, right there.

It looks good, just not what I remembered.

I might have misinterpreted your original comment?

They just looked "wrong" from what I remembered. It's the detail around the 5.7 that was making me think that.

Doing some fiddling with a 6.5 TD airbox on this swap. Finally got all of the pieces together and mocked it up on the truck. I think it should connect fairly well to the 4" intake tube, i'll just have to run a 6-8" section of 4" silicone coupler to correctly make the 4.75"x3" Oval transition to 4" round.

Ordered everything but the AC compressor to totally re-build the HVAC and AC system on this truck. All of that showed up today, then realized I forgot to order a compressor. Hopped on rock auto, found the Four Seasons R4 compressor on clearance for $116! I know I paid close to $200 from them for the same compressor when I did the 90.
