finally got around to starting this project, I will keep you informed of the progress, so far much easier than my 427so weber install.

Chuck, I bet the CAV regs. are adjustable, I just removed the acorn nut from top of regs. and there is a adjustment screw. I have CAV 134 and am about to do what you are doing. Try backing screw off,these are diaphragm style regs,but will they go low enough?
