Transmission Recommended to Run Behind Built 360ci Engine in a 63 Valiant

As I understand it, if you use a 65 V8 904 with your earlier valve body, you can retain the pushbuttons. The 65 still uses the ball and trunnion joint but back in the day if they'd hold up behind a Max Wedge, it'll hold up behind a 360. Of course it would still need to be built and as Mullinax95 said, Dynamic can do it all for you.
