ok, so feeling a little safer with the oil pressure issue, I went back to adjust the timing in hopes of getting it running better and the temps down. Guess what the immediate side effect was when I added timing? Yes, the temps came down, AND the oil pressure went up! I also added 1/2 a quart of oil so maybe it's a combination of things here.

I have a new, adjustable Crane vacuum advance unit that I put on when I did the oil change in November. I didn't have the time to really dial it in until now. But I'm struggling with that. I'll post a separate thread on that I guess.

Bottom line is that the car really likes to run on MVA with a lot of timing (it feels great and runs very cool) but yet I get a bad surging at a steady 3,000 RPM. The problem I'm now having is in getting the timing right with that crane unit. I found the car's sweet spot to be 36* with the help of GTOGeoff. So I have initial set to 12* and added 24* with the adjustable unit using MVA. If I turn the Crane adjusting screw CCW until the idle timing with MVA connected drops from 36 all the way to 20*, the surge is just about eliminated, as is the slight part throttle ping, but the temps started creeping back up to 205* and the oil PSI dropped a bit too. Anyway, here's the vids and pics:

First, here's the view of the gauges. This fully warmed up but temps around 180* and RPM at 3,000 and PSI is 50 (and it's nearly 78* today):



Even at idle the oil psi is up now to 18PSI and water temp was way down, now at about 182* even after driving and idling for easily 30 miles and an hour+ of driving/idling/tuning :




Oh, and as it turns out, my motor is from a 67, not a `70! See date code:
