Knock, Knock ...
By Paul Prokop - 12/14/2002 3:32:26 PM; IP 68.14.53.149
Have a 63 Tbird with a 390 3X2 carb setup. Knocks like crazy under any kind of load.

Have checked all the usual items to no avail.

I have noticed that it knocks until the secondary carbs start to open - then knocking stops like you turned off a switch.

Any ideas on a cause or a fix?
