been doing some reading but hasn't seemed to make the decision for me. seems to be a lot of opinions on either side, so figured I would get some local opinion

1964 Thunderbird, stock 390 (might throw a cam and intake at it, not sure about heads yet)

do I rebuild the stock Cruse-o-matic or find a c6 doner

or something newer.

car is not a resto just something to fix and then enjoy, would love to get cruzing with the kids.

will getting into something with over drive make a noticeable difference on fuelÉ


crazy question

I still have the fully rebuilt 4Rw???? out of my 94 Mark 8 just sitting in the garage collecting dust.
iirc thats an electronic controld trans right?
so not worth the attemt?

adaptorr plate may be lots cheaper than rebuilt or new
