Those allen bolts remind me of how stuck cone washers get. if its' stuck/rusted surfaces, another tool is to put a blunt end chisel into an air hammer.
The vibration of the air hammer is very fast and sharp and does a good job here. I usually put it right into the stud (when doing cone washers) but maybe in this case, I'd hit it on the adapter plate all around the bolt head. But it would have a good chance to booger up the adapter plate. That plus heat usually gets similar items for me.

I don't care about the adapter plates. I might just take my angle grinder and slice and dice. Just need to think about it carefully. I'd hate to make it worse. LoL
Wish I had installed one of those pressure sensors when I did mine, if for no other reason than to get the operating data. I'd love to have high and low side pressure data during operation! I also wish I had installed a trinary switch for my fans instead of hardwiring them to run on high an time AC is on, as an interim solution until I eventually update ECM and go variable fan speed.

Getting a box from Waytek is just as exciting as getting a box from Summit Racing...
I got a bunch of terminals, cable seals, relays, and a few other goodies.
First up is this die set for my Waytek branded crimping tool. This die works on Weatherpack and Metripack (and GT) terminals up to 10 gauge. It crimps the wire and the cable seal in one operation. Can't wait to try it out!
Next up are a couple of my favorite Bussmann panels. These are the dual bus variety. I plan to use one under the dash and add another one in the engine bay for headlights.
Lastly are these heat shrink bulkhead passthroughs made by TE Connectivity. I plan to use the large one for the ECU harness and the smaller ones for anything else that needs to come through the firewall.
The large one is made for a 2" hole and the smaller ones are for .75" hole.

I like the electrical pass through connectors. That one is huge. I was looking at Auto Sport brand before. A lot smaller than some of the other brands while not being as expensive as some Motorsport mil spec connectors
I’m digging all of this stuff your doing. I am glad you’re doing it to the GTO vs. another project car. Maybe this renewed attention to the GTO will gain it some miles. This car is too nice to be a garage queen

Today was a nice day, so I rolled the GTO out into the driveway and decided to tackle stropping down the rest of the engine. Made a quick trip to the parts store to rent a power steering pulley puller and a balancer puller.
Got the PS pulley off without any issues, which allowed me to take the alternator bracket off.
My 20v Dewalt 1/2" impact gun made quick work of the balancer bolt and I managed to get the balancer off without any drama, although I apparently didn't get any pictures of that.
Next it was time to tackle the stuck engine mount adapter plate bolts. I went to my local big box home improvement store and got a torch. Sadly, this did absolutely nothing. There was just too much metal to heat up and the block being aluminum dissipated the heat very quickly.
It was time to get serious. I got my angle grinder out and installed a fresh cutoff disk and went to work. The plan was to slot the head of the bolts and also cut through the engine mount adapter plates. Once the cut was made, I used a chisel to split the engine mount plates to relieve the pressure against underside of the bolts. I was still able to use the 6mm allen wrench.
This worked like a charm. Rinse and repeat 7 more times.
I managed to mostly stay clear of the block, with only a couple of little nicks, but this won't be a problem.
All the bolts had plenty of anti-seize on them, which I liberally applied 12 years ago to avoid just this scenario.
Good riddance!
