    I just got a 73 F engine w/ 4 spd tranny. My '70 F blew. When I swap them will there be a problem w/ the driveline length or do they just fit right in?

    The engine will not change anything in this set up...


    If you are replacing a three speed tranny with a four speed tranny, you will need to find the driveshafts from the four speed truck, or have yours changed....


    Good luck!

    Where are you located? I might have these in my garage. Also, I would keep the 3spd. I've heard that the 3spd actually has a lower first.

    The 3spd TC has a lower low than the 4 spd TC,but the 4 spd trans has a lower low than the 3spd trans.
