L20b 4 speed

Will the 4 speed that behind a l20b in an 80 720 fot behind a z24 in an 83 720

no.

 

But it can be made to fit with some wrenching on your part. The 720 gas engines after '80 were  Z series and the '80 was an L series. The bolt patterns are the same but clocked differently because the two engines sit in the truck at different angles. The only difference between a 71B (4 or 5 speed) for an L series and a Z series is the front cases with the different bolt pattern position. You can remove these front cases and swap them to convert.

 

There were no 4 speed '83s so this will be unique.

Check the length, as long as they are the same length then it's straight wrenching.
