Re: need some OD transmission advice
I'm in a similar situation with my '67 - decided to go with a brand new 4L85E SuperMatic from GMMP. These can be had for $2750 shipped and according to GM good to 700hp/700tq. ratios 1st: 2.48, 2nd: 1.48, 3rd: 1.00, 4th: 0.75
GM Converter, cross-member from Alston, Sweets coolant fittings. There are plenty of hand-held controller options now from TCI, Fast, MSD, in the $500-600 price range.
Can't help on the factory speedo, Jakes setup does have that covered.
