Front 8” HP and FF Rear out of an 80 series. Both are open diffs, front is missing flanges and one hub. Located in Midland, TX 79705. Would prefer not to ship but may be able to meet within a couple hundred miles. $1600

I don't currently have any heater core bypass installed but from what I have seen on other swaps they dont seem to be required. I cant do a file upload to mud but Ill PM you my log files if you want to take a look at them. I think timing is around 20 degrees at idle, tune is still getting...

I haven’t verified the temp. It’s a new sensor located in the front of the driver side head. I did use another GM sensor for the dash gauge but I haven’t adjusted the resistance values on the 80 gauge to get that to read correctly. I’ve been monitoring temps through the ECU with an ultra gauge...

Air was my initial thought as well but I spent 2 days before the drive trying to burp any air out of the system. Originally I did have air getting trapped in the upper radiator hose so I added a bleed port to help remove that. The gap on the shroud to the rad is less than 1/4” but I do plan on...

At first I thought it was air in the system or trapped behind the water pump. I used a vacuum bleeder and then a coolant funnel to burp any remaining air. I’m not hearing any air bubbles in the system at this point. Upper hose was off a 2000 Tahoe (CEL-62262). I later spliced this with a 1-1/4”...

Summit DIY aluminum fan shroud. This is my 2nd fan clutch with similar results, I had a stock one on there originally. No AC yet but the condenser is mounted, I had the heater valve open for the entire drive as well. I changed the upper radiator hose since that photo and added a bleed port to...

Yep, was running at 8500lbs total for the 80 and the trailer. Even at the 15-20 degree weather in Montana and Utah we didn’t see temps drop below 197. I was seeing similar temps while unloaded as well.

Took our recently finished 5.3/4l60e swap on a 1600 mile drive from Montana to Texas. I’ve had the swap finished for some time but haven’t driven it much do to overheating issues. I replaced the thermostat, radiator, and fan clutch before the trip but it still hasn’t fixed the issue entirely...

80 series spare, located in butte. Can bring it to Helena or Bozeman this weekend. Free

Box of 1FZ 80 spares up for grabs. Working alternator, vacuum valves, maf, airbox, blue fan clutch. Located in Helena.

I made a similar set up out of a 3” section of 1.25” angle iron. Used 2 m6 weld studs on the trans tunnel. The 3d printed mount is slick though!

Definitely worth it! I wish I looked at TorFab as well though, the shipping for the radius was nearly as much as the parts. I’ve got the same water pump, no spacers. You just need them if you use the ls3 water pump. It could just be how I positioned the engine but that shorter water pump neck...

Maybe there’s a version of the pump I overlooked. I went with the one Cabledude suggested. I think it’s off a 07-19 truck application.

It’s a Radius fab box from Australia I looked at going with the LS3 water pump to get the front exit but I would need to buy water pump spacers to get the belt alignment correct. I put a new truck pump on before I realized that so I’ll just leave it this way for now.

Making a bit of progress. Would have preferred if the coolant hose went under the intake but it all fits so I can’t complain too much.
