I am planning on coming up to Denver for the next meeting to join R/S if anyone planning on being at the meeting anyway wants to see it run live.
Updates?

Sadly, I blew head gasket last Monday. I'd been fighting an overheating issue I think I had just solved, but too late to save the gasket.

Timing was bad as I'm really busy with work so I haven't been able to make the time to replace it. Guess I'll have to try again for the next meeting in January.

The bottom line is the turbo and it's water jacket complicated things with a new long loop to trap air and I had no provision to vacuum it out. The last thing I did after seeing the temperature spike in the road was fit an overflow bottle made of al with a flare fitting on top to apply vacuum, but it was too late I guess. I had already done the damage the last run. I was literly just trying to get it warm again to draw coolant into the radiator before vacuuming the air out when I realized the gasket was already toast.

Its not all bad. I already had decided to replace my intake with a 3FE, so I had a chance to figure out what had to be moved in order to make room.

Cool. Did you upgrade any internals? Or simply balance the OEM rotating assembly?

Not really. I did coat the skirts of the pistons with a dry film lubricant and the tops with a thermal coating. And the distributor was replaced with a missing tooth wheel on the crank and Ford EDIS ignition.

That's about it at this point but I have a lot of custom parts that I've made over the last few years that will be added to it over time.

Look forward to your progress.

As a follow-up, I discovered that the gasket didn't fail due to heat. It turns out there was a small pinch in the armor around cylinder #5, and that was where the leak started. I just didn't notice it till it failed. It looks like the gasket got damaged before I installed it (maybe something dropped on it?), and I didn't inspect it closely before I put the head back on, my bad.

I'm going to fix a couple other minor things before putting it back on the road. I noticed my missing tooth wheel for the EDIS ignition was off by about 4 degrees, something easily compensated for in the tuning S/W, but I decided to cut wheel another and get the next one installed at exactly TDC before putting the head back on.

Also, I drilled and tapped the head for a third NPT port for a K type thermocouple so I can get a much more accurate temperature reading than I've been living with so far.

The last thing I plan on doing will be to make another downpipe for the turbo that will incorporate an external wastegate since I have a minor linkage interference problem with the integrated wastegate and the 3FE intake I want to install next spring. I also need to fit a floor mounted parking brake lever, its cable coming out of the firewall was the other thing that interfered with the 3FE intake.
