The first time I saw an ATC (plug in) fuse I thought it was brilliant! A glass fuse was not a good design. Not onl;y do fuses can blow at the head where you cold not look through the glass and see the break…. you break them trying to pull them out….glass goes everywhere! The prongs holding them is corrode, loosen up and basically like a “scotch lock” is a future point of failure.
Now the plug in fuses…I remember when we used to call them “European fuses”….further proof Europe is way ahead of us in good ideas!!!! Anyway, we are loaded down with all glass (AGC) fuses in our glove box mounted fuse block 
If you say you wanna get rid of those a huge complete rewiring of the original harness would face you. The AGC original fuse block in integrital to the outside and inside harness…you can’t just take it out!!! So in the past we’ve just polished the grabbers, install new glass fuses and well..what else can you do?
OK Cedric, it’s your fault…after thinking about that a while…thinking Cedric said Ruby needs to include as much new ideas as possible linked to an original prototype #41 GMC……… So to go with the rewire of the harness on the underhood harness
. How about something like this…….. 
The original fuse block has 4 sections…… constant B+ (hot all the time)…..Ignition (on when the key is on)….. Ignition ..off on start (comes on with ignition but drops as the starter is engaged….and that little tiny 5amp. fuse is connected to the dash illumination circuit.
Above, the illumination circuit is by itself in the in line ATC fuse to the left. The 3 ATC fuse blocks to the right top is (ignition is off during start….. the middle is ignition….and the lower is constant all connected to soldered 12 ga. wires to the inlet on each typed AGC fuse prong. yellow is constant, ignition is red with the blue being off during start. Then another 12 ga, wire carries the now ATC protected circuit back and soldered to the corresponding AGC fuse tab.
This way, without scrapping the entire harness which isn’t really that bad….. we can add the new ATC fuse concept to the original harness. One step closer to putting this badass dash together! 
Oops, Jared just pulled in…….. I need to get out there. Come back for page 2, we’ll be breaking down the next 455 Olds motor. Let look to see how well this “non trauma” core will be a good one to rebuild….see ya then.
Today is going to be an on/off kinda thing…… I have appointments so I may not get enough time to finish a long string…I’ll mark “Update 1-2-3…….
OK so getting our break down area cleaned and organized, we just got in a supposed non-trauma core motor., lets focus on the block first. 
Initial inspection says it was probably not driven hard. The concve pistons means those are low compression pistons 
It looks rebuilt with the off color paint but having these pistons…it didn’t belong to Speed Billy! The ridge on the top of the piston isn’t there which means no wear to the cylinder walls 
And a nice smooth, no groove bore. Looking at the valley down to the cam, it has normal wear and the motor is very clean inside. 
Sticking your finger in where the mechanical fuel pump came off you can feel the single row loose chain. This means it’s not a fresh rebuild but the motor has stayed this clean and together not wearing pistons long enough to stretch the timing chain…….I think from an outside look this will be a good core block 
This is an “F5” block meaning it’s a higher nickel content than higher numbers so that’s also good to go 
To me, surface rust is fine and shows the motor has been stored out of the weather for some time…someone I think knew what they had and has been protecting it all this time for us to build a torque monster….thanks man! ….We’ll get into a head inspection tomorrow.

.Finally, thought I’d throw this out, this morning we got in another couty ambulance scheduled for the 20g Stryker stretcher install
In that this is an on duty ALS ambulance we need to get this puppy in and out! 
Here is the unit still in it’s crate 
This unit will support the stretcher as it’s put in and out of the back of the ambulance really helping out attendants backs! 
This work will becoming more of our business as we grow.
OK, that’s way enough for one day…see ya tomorrow and thanks for the visit……
