Getting back here with a general update. I have a few hundred miles on the new front brakes and they're working great now that the pads are bedded in. I went to a Cars & Coffee event about a month ago held at Carolina Dragway and ran the car down the 1/4-mile for the first time since having the current engine and 3.55 gears. Track prep is killer there so there was zero tire spin off the line, impressive considering this car isn't set up for drag racing at all with high performance street all-seasons, Hotchkis rear leaves, stiff-*** torsion bars and zero traction aids but makes about 450 hp at the crank. I only did one pass but it ran a 12.65 ET at 108.15 mph. I'm happy with that and it should still get better once I finally get around to swapping the shorty headers and dinky 2 1/4” head pipes for Doug's long tubes and 3" pipes back to the mufflers and a more performance-oriented carb. Here's an in-car video of the pass:
