I just bought a beautiful 1951 5 window Chev that has a stock 4 speed, orginial rear end (inclosed driveline) and a 261. I want to keep the 261 but change over to an automatic (maybe a 700R4 if possible)change the gear ratio in the rear end so I can cruise the freeway. What parts do I need?
If I can't use a automatic maybe a good tranny with overdrive. HELP. Also need a Rochestor BP carb for a rebuild.
