It is funny how many Ford and GM guys dont know what our older B-bodies are. Heck even a guy with a 340 Duster (younger guy) thought a guys 65 Belvedere was a Chevy ?? I even had some young girl ask me if my 63 was a Mustang ?? I am not kidding either. Thats a nice sleeper you have there GY3. Ron

GY3.
Pull up to the line, purge the system but find a way to shut it off (I don't know much about NOS systems, never will, never care to) anyway, pull your low 11 times under the assumption that it was on the mojo.
Wait for the roaming sharks to arrive after that chum, and then put it to 'em with a mid to bottom 10 $lip.

By the way, one AM while waiting for a run at the haunts, my car got mistaken for a 65' Chevy II. Honestly, I could see that resemblance via the small rear single taillights and boxy body style.

That thing should scoot with a little juice.

On my previous car I "hid" the system, but this one it is in plain sight. I rarely open the hood anymore anyway.

I've got a couple of ideas for hiding solenoids and a bottle.
