Stop in for a cup of coffee

The builder jacked around with the valve body. I would need to find a 64-65 pb valve body and see if that resolves the issue

I have a good V8 pushbutton to go behind the small.block
I believe that v8 valve body is the same.... but good you have the parts to swap it out. not a slip yoke then? I know yours is a 64 but mopar did silly **** with mid years... like my 62 has 61 k-frame/motor/trans mount
