does anyone use 100LL av gas ?

no worries ! and it ain't no Yellow cab. It's a 67 Fastback with a B wedge and cnc ported aluminum heads.
photos Will be posted this spring, courtesy of my wife. she is also going to post a picture of the 63 fury with 6 pack RB.
The wife really wants me to go over and smoke your ***. just maybe you can beat the truck, maybe if it's detuned, but I doubt it.
PS I'm not no Yellow Rose or Yellow Cab. just maybe you can get together with your buddy YR and skrews and formulate your exit strategy.
if you're looking for a challenge out of me you'd better hurry! I've already taken the big cam out, the roll bar out, and added lots of interior. my next step of putting 3:55 gears and to replace my 4:10's and some quiet or Mufflers are going to make me even less challenging....
