Fury Fan --
Thanks for the compliment. In 2016, I was fortunate to buy "Big Red" from a lady in Wichita KS who was closing out her late father's estate. It really wasn't in too bad shape, but I had the trans rebuilt (parts were rather hard to come by here in Colorado Springs), replaced some of the chrome trim with proper SF trim, put the proper "Commando 426" decal on the air cleaner, and replaced the damaged valve covers which somehow got stuck with "426 Super Stock" decals; these may have been put on when the original cam, while not exactly mild, was replaced with a bit more wicked one. The present cam is very, VERY rough idling when cold (like about 2000-2400 RPM), but will settle down (somewhat) when the engine is at a normal operating temp to about a 1400 RPM idle. If my memory serves me right, that '65 SF I had back in '64-'67 idled at about 750 or so even cold, but I'm not about to change it as I love that lope. It also lost its viscous drive for its fan (those things usually took the deep six after a while) and I may get a Mancini replacement just for appearances sake though it's hardly necessary.
My wife and I enjoy the car very much and though we don't abuse it like we did the first SF, I have no compunction on "blowing the cobbs out" every now and then as it is easily pegged. Nor do I back away from an occasional challenge at a stop light and in fact, after one such confrontation, a Beamer guy followed me into a cruise-in just to tell me he didn't expect "that big old car to be that quick." It's a great car.
