I've posted several issues I had when I put a MSD distributor, Holly 08007 4 barrel carb and a 1957 intake manifold.
Happy to report the car is running perfect, all the issues fixed except the trans mission . When I stop the transmission acts like it wants to shit to another gear only briefly.

How do I make the adjustment to get my transmission in sync with my carburetor?
I have a 272 y-block and a Fordamatic  transmission ?
