I'm going to swap a 472 into my down sizing 78 fleetwood.
I have a few question about tranny.
As I know both 472 and 425 will come with THM400 tranny (for RWD)
But the THM400 that come with 472 (from a 74 fleetwood) look obviously longer than the one in my car.
At first I thought that i will use my old tranny.
But i just wondering if there are different version of THM400 in 472 and 425.
Should i use my old tranny or use the one that come with a 472?
Anybody have a clue about this?
