I've just gotten my hands on a '64 SB Fleetside and am jumping in with both feet here. I found a new crate 350, so I grabbed that, and found a T-56 out of a '94 Z28 over in Tucson, and I just
had to try it.

The idea of having a 6-speed tranny with 50% overdrive in top gear was just too cool to turn down. Now, though, I've figured out the shifter handle is going to be back about 16 inches farther than the old 4-spd shifter was, so I have no options - buckets are mandatory. Also, the T-56 has an electronic speedometer feed, so I have to either go to a new electronic speedo or get one of those converter units I saw online somewhere. Now I'm wondering what else I didn't consider, since I had never even seen a T-56 before!

If anyone has any tips or suggestions, I'm sure open to advice!
