I agree about the mph, but I would rephrase. Mph will be more indicative of what it CAN do, with a more drag oriented setup. Poor gearing and poor tires will make the E.T. poor, mph will tell you more about the actual power.
Interesting! I'm very new to running 1/4 mile (have made about 15 passes in 5 trips over a few years).
Best time my car did was 12.80 sec at 108 mph. I've consistently run high 12's to 13.0 and mph between 103-112. Funny my fastest trap speed was not my fastest ETA. Probably makes sense to those with experience. Nitto 555R drag radials. Sea level. 90F outside temp in August northern California, low humidity. Similar times different track, sea level, 75F outside temp September, low humidity.

Just based on the above, is it possible to estimate if the car is capable of improved ETA (say with a better driver or better tires)?

Yes for comparison on your 12.80,, my 64 runs low 12.60s at high 105/106. With a 383.
If you did indeed run 112, you should be seeing a 12.0/11.90 area.

Thanks. Yeah, I expected my mild 451 (391 RWHP, 523 Ft-lb RWT) to run much faster than 12.80 (which is still not bad for me). I think I need more practice, but the nearest track is 90 min away. I think my biggest problem is the launch since I don't want to spin the tires too much.

I weighed the car a few years ago and it was 3700 lbs without driver.

Wallace racing has an "ideal" calculator (basically a stocker/super stocker quality chassis). Theoretical best for 108 is 12.20s, 11.80s for 112. The theoretical would have to include perfect traction, correct gearing for the application (probably not something you'd want to drive on the street), and a bunch of converter.
And 3700 lbs is typical for a big block 68/69 b-body.
