Ended up buying a new carb and man it made a huge difference. I still have quite a it in RPM drop but I am about 80% sure it's because of my converter not being high enough stall for my cam choice. I am now shopping around for a TC.

Specs are as follows. 440 30 over .538 MP cam 727 Not a stock converter, not sure on the stall though. eddy 1407 carb Started reading another thread and saw that he was having what seemed to be the exact same issue I am having. In park, this car idles like a dream. However in drive or reverse...

The fel-pro gasket set came with 4 paper gaskets and a metal pan. I cant use the 4 gaskets with the pan because i cant get the bolt hold to line up. The bolt holes line up perfect with the paper gaskets with just the metal pan. I have a hard time believing that fresh heads from a machine...
