I had a worn out 250 inline in my 68 impala in highschool. It was a boat. the biggest performance increase I ever made to it and just overall made it 10 times better was fitting a nv3500 5 spd to the back of it from an s10. The closer gears and overdrive made the car a lot better at accelerating and mpg. Like a ton. It would burn rubber through 1st and chirp 2nd.

But I definitely understand keeping the original gearbox. Cool truck!
