Welp, not much to report. Did some more driving and tuning. Car is definitely driving nice now, and reliable. Believe it or not, not a single stall since going to MS3. Idle has always been reliable. But car is to the point where I can hop in it without hooking the laptop up and just go take it down the street and back.
Have learned a few more things. Learned how to optimize my idle advance. Had too much advance which had it running well, but softened some of the cam chop. Found a nice midpoint that was still reliable but got a bit more chop. Happy with VE table for now, working on some Accel enrich. Not a whole lot of opportunity to work on that now, as it's just getting too cold. Tires don't grab well so hesitant to jump on it to refine WOT and AE. Might have to call it a year.
Not much left to do on this car. The only suspension part left hanging is the torque arm. Hesitant to drop $800 on something I likely won't really do much spirited driving with.
I'll be 100% honest here. I think I went too far with the car. It was nice to go crazy and do all the mods i wanted to do when I was 18, but at the end of the day I don't think it's was worth it. What i should have done was the 5-lug conversion, stuck with vac brakes, found a good spring/shock combo and did a simple GT40/N61/Cobra intake combo that will run well on an untuned A9L and called it a day. DOn't get me wrong, i like my car, but I do think I overdid it.
On a nice day, my bone stock SN95 convertible was the car I pulled out of the garage first. Stock, smooth, reliable, simple mods. Sounds good, and I can sit in 2 hours of traffic with it (I have). I think i'm getting into the "driver" phase of my life since turning mid-40's. Which means I want a nice clean stock car to cruise around with. I put over 1K miles on the SN95 this summer. I put maybe 50 on the Fox.
I might close out this project thread. Not much else to do to the car really.
