$200 K5 (454 K5 now) *too much junk in the trunk

Getting a few things ready to go in. The new 454 TBI is on using the adapter I got from @6872xtc. Should work well, nice part. My 454 TBI uses different connectors for the wiring. The Throttle position sensor on the '90 Blazer harness (tbi 350) is different from the '92 TBI connector. Ordered a pigtail, anyone know how to figure out which wires line up? The Idle speed motor also uses a different connector, ordered one of those too. I want to keep the '90 harness in place, just switch the computer and connectors as needed. Looks like most of the other connectors are going to work.
I wish that I had known about your TPS problem. I would bet that I have an adapter harness here. Ah well..
It will be neat to see this running!

Didn't realize I had a problem until last night. The connectors have the same number of wires so I will have to see if the colors are the same or not. I still have the '92 454 harness so hoping its just change the connectors. If the colors don't match then I will have some tougher figuring to do. I am sure the info is out there but I haven't found it yet.
Checked the harnesses, wire colors are the same, should just need to swap the connectors.
Just got a box from Carbondale. I love boxes from Carbondale!
I did not know ORD made inflatable coil over kits. Nice.
ORD engine mount/crossmember?
You are correct!
Put some paint on the crossmember kit last night. I was going to need new engine mounts so I figured this was the way to go. It should hold up well to the big block. I also had some light contact with the drag link and crossmember at full stuff so the crossmember made sense.

This came from @folkenheath about a week ago. Long backorders from Edelbrock moving production out of CA during the pandemic. Time to get things back on track.
I got the 454 in the K5 last winter and was moving forward with the TBI stuff. I kept having a feeling it was never going to run right being a bored 454 with a performer cam. Howell said they could burn a chip for it. Lots of guys have said that they got their swaps to run ok this way but nobody really was completely happy. Little issues from the TBI not liking anything but a stock engine. I decided to just do it right from the start and go to the ProFlo4. Then I found out I couldn't get one. Watched availability for months and never any stock.
In the middle of winter I blew the engine on my Polaris Assault. Destroyed the PTO side crank bearing on a 3ft powder day. Had to switch gears and do an engine swap on the snowmobile. Did a long block and it blew up on the first pull! Engine had a warranty but that took a few more weeks. Got the sled back together and finished out the winter, everything worked great.
After winter we are still in a drought. The fire danger out here in the west is crazy. I needed to do a bunch of logging around the cabin at 10,000ft, beetle kill trees everywhere. The best vehicle I have for logging is my deuce and a half, that needed a brake job. 
So instead of working on the K5 I did a brake job on a very large truck with heavy difficult everything.

Here we are mid July and I now have a ProFlow4 in my hands and its time to get this project back on track. The instructions from Edelbrock are pretty good, just need to go through the steps and see if I can get this thing running.
I have the Pro-Flo4 bolted up and am hooking things up. Fuel lines and plug wires on the way.
Which radiator should I run? @mrk5 is running the diesel one in his big block rig. Its about $500 from Oreilly, the 454 one is about half as much. Read through @mrk5's build thread and he fought fans a bunch. The proflo has trigger wires for 2 electric fans built in. I am open to using twin electrics (flex a lite kind of spendy but whatever works) to use the proflow setup. Mechanical fans pull great but I only have a few parts available in my stash. A stock reverse fan off a tbi 454, not sure on the shroud, it was a gmt400 truck. Also have a few other random square shrouds but not the specific diesel one. Electric would solve the fan and shroud all at once.

You know from my thread I really didn't like the mechanical fan, especially on the trail. Just too obnoxious sounding when the clutch is engaged. I would however like to try the mechanical towing to see if it's better.
I'm pretty sure @skunked has a standard big block radiator in his K10. I put the diesel radiator in to replace the small 350 radiator. I didn't want to take a chance on the in-between size not being enough. The only time I have an issue now is towing our camper up the bigger passes.

Big block radiator with windstars on the 84 and a drop in aluminum radiator with e-fans (Amazon special) on the 74. Both have 454’s.
These have to be junk right?
$369 for 4 core with fans
$265 for 3 core with fans
@skunked, are you running one of these?
I had a nightmare with the Champion radiators in my buddy's suburban. Want to stay with parts store available stuff but those are not very good anyway, just easy for warranty purposes. Very wary of the china radiators, quality control is terrible. A flex a lite dual fan costs more than fans with a radiator from amazon.

Griffin with fans is $1200.
Auto version shown, seems nobody has a manual in stock. Probably because the auto version would work for either trans. Nice looking unit, hate the price.

I hear mishimoto brand is good. I think mine are Spectre, but they're getting hard to find I've heard.
