Looking for input from folks on what to do here.
I have 1960 (early) BN7 I plan on restoring. Transmission does okay, (and a whine in it or OD there somewhere). OD unit takes a while to pull in and slips or pops out when good and warm. I planned on rebuilding both so they would be 100%. I knew my car had the engine swapped out when I got it. Today I pulled the tunnel cover off and find out its got a 100-6 transmission and OD unit. Trans is AEC3174 serial B5483. I can't find reference for that but I think its 100-6, and O/D unit is 28/1447/006377
While I have thoughts of trying to keep car as original as I can, I need to decide whether to try and find the correct trans and OD unit. To keep the existing, or maybe go with a centershift. My looking at the the ratios, it looks like the finale ratios to the ground for the 100-6 and the BN7 are close, the 100-6 looks a little wider range, but that might be splitting hairs. I plan on installing the BJ-8 camshaft. I also thought about going with the HS6 or DH8 carbs, but I might keep my HD6's. Would any of those things make a performace , driveablility or reliability difference? Would the correct trans and OD be better that the 100-6 set up. I am thinking if I am going to rebuild them both, maybe I should rebuild the correct ones.
And does anybody have the the correct trans, or overdrive they want to sell. ( I think that would be AEC3524, and 22/3009). I am fixing to put an add in the forum classified. With people converting to 5 speeds doesn't that make some of these available?? ( I don't think I want to go to the 5 speed, I like the OD set up.)
