I decided to hitup the MBCA autocross. It was mostly a success. I tried not to push the car too hard but also give everything a good workout to get a feel for what needs work. It doesn't seem to be seeping much oil from the front on the intake anymore which is good. I'm thinking the extra advance was causing the crankcase issues but I'll be sure to keep an eye on it. Unfortunately it died on me on 4 of the 6 runs. I figured it was the carb not liking the cornering too much but it seems the issue might be a bit simpler. I talked with my dad and he thinks my primaries are too rich causing it to load up on fuel when the rpms drop. This would explain why it was giving me trouble to trying to restart it on the course and why it was behaving perfectly fine as long as I was giving the gas pedal some love.
The rear was only rubbing on the driver side and only just barely hitting the sidewall. A rear swaybar and some fender massaging with solve this issue just fine. I'm not too worried about it since I'll be running a different set of tires eventually for anything involving cornering. I'll probably go with another 1/2" of backspacing as well since I have the room. Speaking of the rear tires: the car did launch pretty well, I didn't go too HAM but there were no wheel hop issues or any weird vibrations.
Here's a video of one of the runs. I can't seem to download it and facebook utterly murdered the quality even if I could.

So at this point I need to either start pestering Coy Miller, learn how to adjust the carb myself or go with an EFI system. I was looking into the Holley Sniper system and it looks impressive. All it would take is some wiring, a return line and finding a place to mount the fuel pump ... and about $1,300. It has the added benefit of being able to work with their distributor to control timing with a handheld device.
My body is telling to just buy the EFI, I rarely hear of anyone regretting the purchase but my bank account, my bank account is telling to use the calibration kit in the garage and figure this shit out for myself since it's not rocket science. Decisions, decisions. Either way I need to start with a proper exhaust system and O2 sensor.
Oh yeah so I think using the donor K-member is coming back to bite me in the ass.

That's where my lower control arm bolts in case you were wondering. We patched it well but I didn't consider the alignment issues this would cause down the road until someone brought it up. In my defense, at that time I was still mostly just building this thing as a weekend cruiser with the occasional drag strip visit. Looks like it's time to start looking into tubular K-members. QA1 makes one but it's only for the earlier style motor mounts that had a bad habit of breaking regular under motors with any kind of torque. If it wasn't for the steering box being bolted to the K-member this would be a fairly easy swap. It would be the perfect opportunity to get hydroboost setup done at the same time though. Anyways, stay tuned. Big things happening this winter, I told you this was a never-ending story...
