Out of town most of this weekend for a tournament, but I had a few hours today to work on the car.   Decided to take a break from plumbing and work on the rear suspension bushings so I can get the half shafts measured.

The upper control arms weren't too bad, they fit fine in the press.   I cut the old bushing "lips" then pressed them out, popped in the new ones and reinstalled.   The lower arms though.  Oh, the lower arms.   They have bushings pressed in from each side, that fit snug against the arm.   The first one I tried to cut with a bandsaw then clean up with a flap wheel to get clear.   That sucked.   The other one I decided to use an air hammer to catch the lip and force it away from the arm.  Then I took the bandsaw and cut it back.   Way easier.

But, the arm didn't fit in my press, I couldn't get the bushings out with a c clamp or a vise, or the air hammer.  Or a hammer hammer.  Or profanity.   I did make a giant mess of myself though.

FINALLY I cut a piece of tube that fit the bushing, made a "back plate" for it, then used a bolt and not to push the bushings into the tube.   Took me 2 hours to come up with that idea, but hey, it took 10 minutes once I came up with the idea.   New bushings also somewhat sucked to get in place, but I was successful on that effort and the arms fit the car properly.

One more lower arm to do, but that's for another day.   At least I have a plan for the fronts now, though they still need cleaned up.   Once the other rear arm is done, I'll measure suspension to figure out the travel arc, mark that, and then sort out the half shaft sizing and get those made.   That's the last "wait for it to be made item" so it makes sense to get them in production while I finish the wiring/plumbing/fuel system.

Progress.  Slow, tedious, progress!

Rear suspension is done.   Decided to get back to the plumbing.

When I built that custom AC bracket up front for the compressor, I flipped the compressor over.   When I took the cover plate off and it peed the pre-loaded oil all over the floor (whoops) it occurred to me that it probably shouldn't be mounted upside down.   Read the instructions and yeah, it shouldn't.  Great.

So, that derailed today's activity.  Pulled the assembly off, and started reworking the bracket to let me flip the compressor.   About 2 hours with a die grinder adding clearance where needed without taking away too much meat and it fits.   Step 1.   Now I have to make the lines fit.   So I had to adjust the power steering lines (we'll see if they are happy or need some rework, but even if they do need work later it won't be a big deal).   I made a hard line "extension" off one port and ordered a 135* fitting for the other to get the clearance where it needs to be.   It looks like it'll all work at least.   AC lines are always fussy for some reason.   I also got the charge port locations validated and found a port adapter to let me run the GM AC pressure sensor to keep the stock ECU happy.   Progress!

Anyway, back to OTHER plumbing, I redid the oil cooler line that I smashed one of the times I put the engine in/out (whoops) and got it installed.   I then started work on the dry sump lines.   The "in" line for the engine was a little close to the subframe so I added a divot for better clearance during movement.   That line is done.   Next was the "out" line, which I had designed with a straight fitting.  Yeah, that won't work in situ, so 45* fitting is ordered.

I swear I could buy another car with the money I have in "whoops" fittings.   Ah well, hoping to finish plumbing the oil/coolant/etc. lines by this coming weekend.   Then I think I'm going to do the fuel feed lines and the rear half-shaft measuring, then wiring last (since that's the "relaxing" part for me).

Everything came in to finish the engine bay plumbing.  I also ordered/received the 4" aluminum mandrel bends for the intake pipe, and a K&N to stuff in the fenderwell (where the OEM filters were).  If I get free tomorrow I'll finish the oil hoses, A/C hoses and get started on that intake piping.   I'm excited to get the intake in, and the oil breather system done as that should basically finish the whole engine bay.

Add trans/diff coolers and fuel feed and 100% of chassis plumbing is done.

Oil lines are done.   A/C lines are done, minus final tightening (will hold off until the engine runs for sure).  I also mounted the intercooler pump and finished those hoses up.  Intake is also designed, in theory at least.  I need to fit the wheel liner back up and make sure it clears, if not I'll mess around with it a bit more.

Next up is the vacuum pump for the brake booster, and then the fuel lines, breather lines (I need to add some -10 bungs to the intake pipe for the clean side on that also) and the oils/trans cooler lines.

Then wiring and start-up.  Knocking stuff off the list, slowly.

At first glance it looks factory, but then you notice the AN fittings and billet details.   :drive:

Thanks guys!

The intake tubing will definitely be wrinkle black, and I may do the blower lid and dry sump tank in wrinkle black eventually as well.   Only to make it all a little more subtle/classy.  But I don't hate the silver bits, honestly.  They play on the aluminum chassis a bit.

Definitely going closer to that OEM almost look like others have said, the blower lid in the silver I think has a nice focus myself in the engine bay for some contrast. Wrinkle black on the intake for sure adds that OEM+ look though.

This is so much awesome here!

Agree on the intake tube, but I'd def leave the blower lid natural, and to be honest, I'd hate to cover up those beautiful welds on the dry sump tank as well.
I think the contrast dresses up the bay a lot, without it looking too overdone.

Hmm, being the lazy sort I am, I avoid painting aluminum parts.
If they're not painted, the paint can't chip / flake / fall off / fade / get scratched.
Just my .02, whole engine compartment looks frickin amazing right now.

I agree, low maintenance is a big advantage.

I used POR15 Glisten PC clear on the aluminum heads, intake and polished valve covers on my Ford 427 way back in 2000.
Aside from slight browning on the exhaust ports, it's held up flawlessly, and still looks as good as it did 24 years ago.
It's proven impervious to gasoline on the cast aluminum intake, and prevented any staining at all when gas was spilled.
I wouldn't hesitate to use it again on any bare aluminum I wanted to protect.

Yeah, I think you have a good point on the lid and tank.   The intake tube absolutely needs to be black though, for sure.

I am planning to have a little stainless plate etched with an Aston "wings" logo to put over the "LT4" inlay on the blower intercooler coolant manifold though.  That's the last thing that tells someone that's "sorta" knowledgable what's going on here, so I want to hide it a bit.  I also kinda want to put a GoPro under the hood at car shows to see who actually realizes what's going on.  No one ever really paid attention under the hood of this car stock.  Everyone wanted to see/sit in the interior or just look at the car, so I'm really curious if anyone actually notices that something is "off" under there.  :D

On the "Blake hates money" front, I bought a lithium battery and charger for the car.   The stock battery is HUGE and weighs 60 lbs.  Gross.  The Lithium weighs 19 lbs.   So I'm saving ~40 lbs. with the rotors and ~40 lbs. with the battery in the car.  I also pulled out a little bit of sound deadening (maybe 5 lbs) and I know my radiator/fan setup and shifters are lighter than stock.   So maybe 90 lbs. of weight pulled out?   I'm planning on Cobra Nogaro seats stitched to match the interior next winter (hopefully) which should pull another 40 lbs out of it as well.

I'll be stoked if my final weight with the new drivetrain is equal to stock;  I don't think the LT is much (if any) heavier than the Jag/Aston 4.3L DOHC that was in it, but I know for sure the TR6060/Z06 diff is heavier than the Graziano.   I guess I should have weighed the engines considering I own scales.   LOL

Was the old engine supercharged? If the old motor was supercharged I'd expect to be 40-50lb lighter given all that you've replaced.

What AH was the old battery? 19lb for a lithium seems really big. Lithium has a much wider range range. You can run nearly half the AH and get the same result
The battery I'm using is about 7lb and cranks my LS7 like it's not even trying. Doesn't even drop below 11.5v cranking.
