Re: EGR or NOT?
Well mine does, just like the old fresh air gulp valve I've got old
broken off drill stuck in the vacuum hose to plug it so it just looks
like it's connected. The vacuum port starts from the manifold port below
the idle jets, to the thermo valve:
http://www.----------.com/vacValve.jpg though the decel valve:
http://www.----------.com/decelValve.jpg that's controlled from the
venturi port up near the choke of the Ford two barrel:
http://www.----------.com/fordEGR.jpg Looks like they're run under full
vacuum at AMC too:

Re: EGR or NOT?
I don't care what you plugged or didn't plug, introducing exhaust gas into
the intake is not going to make it backfire. That is an AIR problem. The
fact that you prolly disconnected everything in sight that wasn't found on a
1957 Ford, including the AIR sytem, when you disconnected the EGR would
explain why the backfire stopped when you disconnected the EGR. Replace the
diverter valve and reconnect everything and I think you'll find the backfire
disappears. The properly operating EGR also allows the ignition timing to
be run further advanced without severe engine ping, a huge advantage. So
many people yank everything they deem non-essential (or discreetly plug
them) then wonder why the engine pings like a bitch when timed to spec, or
ends up not able to advance ahead of spec without the ping, sees no
improvement in performance or economy, then curses those "eco-****'s" for
all their problems.
Had to say it.
