I think it's in the car.

That would make it difficult to flip over then.

Did I read that right, this is a 469 with iron heads, 10.4 SCR, and an XE274? And there's no detonation with 32 degrees and 18 degrees vacuum advance?

Whew! I was getting tired of holding the car upside down with one hand while holding my camera in the other!

I'll put a vacuum gauge on there and see what it's doing at 3,000 RPM. Good idea. Can I connect that gauge to a ported line since that's all I have left open? if not, I'll just pull another hose off the carb temporarily.

But yes, when it's got 36* of timing at idle (12* initial + 24* MVA) it feels great as I let the clutch out - SOOO responsive, and the temp immediately dropped to below 180 even idling/driving/idling for nearly 2 hours of testing.

Anything more than 12* initial and it gets hard to start. I have a high torque starter, but I suspect it's a cheap one (note how they spelled "protork"). found the link to the starter.

Wait, I have a picture of it here somewhere... FOUND IT! This picture I DID take with one hand while holding up the car with the other. I know, I know, I should really have set it down on jack stands

Absolutely correct! That has stumped a few others too, including Richie. But his ears also agree, no detonation (well, until now on part throttle as I mess with the carb, but when I had the holley on there, no pinging anywhere on pump 93)
