Can I ask you some questions about 3d printers? You seem like one of the more experienced guys around here.

Absolutely. Shoot me a pm

That water logged 5.3 shortblock that Michael dropped off a couple weeks appears to have a salvageable crankshaft. The rings, lifters, cam and timing chain were rusted solid but all bearings look good. It needs lots of simple green and a little elbow grease.  I plan to throw this crank in my L33 block and do a sloppy sloppy rebuild.

That is quite amazing, really. I expected it to not even come out.....

I even did it without a sawzall.

Scooped this drill press from work before it went in the dumpster because "the motor doesn't work".  The drive pulley was loose on the motor shaft and the fan blade was rubbing against the metal shroud.  It'll work just fine for me.

I'm repurposing some dumpster metal and redesigning the lower rad support so I can push the radiator forward.  The radiator will sit straight up and not be angled anymore with this change.  Should give more clearance to the intake and give the option for some fancy heat extractors in the hood moving forward.  

That Bussmann fuse panel is cool but I don't have the time to sit and figure it out this year.  I'll be damned if I don't put more miles on the truck this year than I did last year.  So I'm putting the bussman panel on the shelf for now and doing this the easy way so my smooth mechanical engineering brain can figure the wires out quickly.  This panel is going to go behind the passenger seat.

So scope creep mcgee back at it again, because why not?  So I have a VS7875 sitting on the shelf and an air to water intercooler I bought off of Obsolete a couple months ago. Both of those parts have been talking to me a lot lately.  Now I don't plan on doing anything with them right now but I will say all I need to add to my parts stash a heat exchanger, water pump, turbo manifold, wastegate, fuel injectors and map sensor to do a turbo LS build.  It's not a long list an I think I have a very GRM way off making a heat exchanger for the A2W setup.

The radiator in my Yukon was leaking from the plastic endtanks over the holidays.  So I swapped it out with a fresh GM unit and didn't throw the old one away like any good hoarder.  Fast forward a couple weeks and add a couple beers, what if we cut horizontally along one of the rows of fins and made new endtanks out of that cheap aluminum sheet I bought off of Michael? Could that be used as heat exchanger for an A2W intercooler? OEM style tube and fin HEs are pretty efficient and simple construction.  Seems to check out, what could go wrong?

Leaky plastic endtanks removed.

Some 1.2mm aluminum sheet practice to make sure my welder and myself are capable of this project. 

The core is 34" wide which is huge! Thinking about cutting it down to about 10" tall. If I'm going to use this chopped down radiator I need somewhere to hide it.  We will see how this splitter turns out in 3D printed pieces.

The water ports on this intercooler are 1/2" NPT.  I hate NPT fittings, they always leak, so they must be deleted. 

I have a few -12AN pushlock fittings and a bunch of -12 to -16 male to male adapters from Holley clearance.  Bandsaw the -16 end off, sand off the anodizing and it makes a great AN weld bung.  I found a couple LS heater core hoses I replaced recently on the Yukon and Escalade but never threw away. The benefits of parts hoarding are starting to show through.

The trouble with aluminum is it doesn't cut well or really at all with abrasive cutters.  Toothed blades, both reciprocating and rotary are pretty aggressive for thin aluminum.  I found that an oscillating tool and a wood blade make really quick work of of thin sheet and radiators.

I've been looking at this turbo stuff a bit too seriously.  The LS3 manifold I got from Garithon fits almost too well for a cross over.  It needs a V band and a dent in the firewall but that will play.  Plan for the passenger side is to get another stock manifold, chop it up to accept a 2.5" crossover and place the T4 flange where it needs to be for best downpipe routing.

Fender dumps are cool but I'd like to put a full 4" exhaust on this thing if I can.  It's looking like I might be able to make that work.

I've been busy being stupid.  3 kilos of PLA later I have V1 of a splitter.  It sits a bit lower than I anticipated but I think that can be adjusted. Plan is to use this as a buck to make a fiber mold.

It's starting to turn into full blown spring in SC and this thing is still on blocks.  Turbo plans are on hold, full steam ahead on uncobbling. More OEM Corvette parts and chinesium procured on eBay.

Super cool stuff going on here. It's awesome that you can model the splitter like that.

Some uncobbling requires a different brand of cobbling.  The PS pump on the truck requires an external reservoir that makes changing the spark plugs difficult.  This pump came off of the wife's Escalade because it was leaking from a rust hole, JB weld should do the job until I can get a junkyard one.

I promised more eBay Corvette parts.  I recently discovered in one of the Youtube build threads I follow that C6 Corvettes have a hand brake that attaches to the side of the trans tunnel with horizontal bolts.  Most cars I have seen have handbrakes that attach to the top of the tunnel with vertical bolts, the CRV hand brake in the background included. Mockup below; I need to adjust the tunnel a little bit to get it to sit lower but it looks like a great option for $60 with the cable.
