I have been looking for the radiator hoses and finally found a perfect match for the 1 1/2” return line. Purchased from NAPA auto parts PN# 708
I ordered a couple upper 1 1/4” hoses and will get tomorrow and hoping one of them fits.

This thread is SO awesome...!

Installed upper radiator hose. Picked a hose out of NAPA catalog and it fits, but going to keep my eyes open for one that either hugs the radiator closer or the power steering reservoir. Part # 8379

Rebuilt rear sway bar and finished up rear adjustable drop links. Because I kept everything metric on the drop links, i had to turn the I.D and O.D of the SS insert for the hiem joints, should have just made alumiunm inserts.

Tackled the electronic throttle pedal mount. I ended up using the stock aluminum 928 casting. I modified the bracket and welded a 3/16th piece of aluminum plate for the throttle assembly to bolt too. It is a very tight fit between the steering column and firewall. The pedal is as high as I can go and still access the hole in the fire wall for electrical cable. If need be, I will cut the steel pedal arm and fabricate to adjust.

Wow! All the things I have to do, I really appreciate this thread and your great pictures and descriptions! Do you have the oil line fitting part number list by chance? I would like to build my oil lines as you have, but haven't cracked the catalog yet.

Mounted the main fuse box for the LS wire harness. There isn’t a lot of options on where to mount. Looked at inside passanger foot well and not enough room. I went with same location as where Dinsdale mounted on JP. The only differences is JP has a Camaro crank,on his LS and I have a corvette, the corvette has the pulley much closer to the block and the alternator is mounted on top. JP is a much better setup for the conversion and allows for more room. My install went fine and everything fits, but I am still looking for a bracket that puts the alt. on the bottom, I think it is a cleaner look and provides more room. I used thread inserts to mount plastic box.

Mounted the ECU in the passenger foot well where the stock computer was mounted.

I buy most of my stuff through Kartek Ihttps://www.kartek.com/
I am a off-road guy and have used them for years.
Remote oil filter (uses a HP6 filter). I ran -10 AN fittings and SS braided line. Fittings are anything from straight to 180. I purchased a tool that makes putting the hose on to the fitting easy and no blood is involved.
Hopes this helps.

I am an off road guy too, am putting a similar engine (LS3 525HP, 8L90, Atlas 3.8) in my chopped '79 Cherokee Chief, hence working through this conversion in my head and vicariously through your build. Too late for your build, and your way is better, but for anyone else that may read this, the fuse box that comes with the GMPP LS3 harness is from an astro van and in that application there is a bracket that bolts to the car and this box snaps in it. You can get it from the dealer.
Am putting the 430HP in my 928 in front of the rebuilt factory auto.
Thank you for the parts listing, did this for the Jeep, but your fittings and hoses are more elegant than mine.

Made aluminum radiator tank. Have a few more bungs to weld on for more lines, but waiting to figure out all the hoses.

Welded in aluminum plugs to delete door locks and decided to delete the door edge lights as well.

Picked up used 1989 928 door lock assemblies. Will switch out with vacuum controlled ones which will allow for electric actuator remote control door locks. The new actuators have the plunger connection 90 degree off fron stock, so I cut the plastic arm and had some aluminum tubing that happened to be perfect fit for the plastic to slide into. I expoxy the piecess back together. I also had to drill out the hole to fit stock pin, sand down thickness so plastic arm would slide over plunger arm.

You are quite the fabricator... nice work thus far!!!!

Thanks for the kind words.

I am constantly learning, which makes it fun.
