27,000 original miles

Welcome to FABO, a cool and rare car you have there!
However, rare doesn't always mean fun or valuable.............
I would drive it for awhile the way it is, but i think a V8 swap with a 4 speed is in your future.
A tough call to make for sure, but i would tend to leave it the way it is, but that's me..............I like the weird.
I think it would actually increase the value by quite a bit if you did a 340 and a 4 speed swap, should you decide to sell the car in the future.
