Scored a 235 yesterday

[BrianDamage]

I found it on craigslist, and the price seemed right...

It's got a muncie 318 attached also. ..supposedly whoever this guy got it from had it in a 57 chevy truck...the motors numbers ID it as a 58

Ive got a 51... it was my uncles, and he always wanted to keep it original...so I want to keep this truck BASICALLY "stock",,,at least in appearance...meaning I wanna keep the 3-speed on the column

one concern i have is the cost/upkeep of coverting the old torque tube rear end to more hiway-friendly gearing... would this muncie 3 speed bolt up? it's for a regular drive shaft, so Id have to get a rear end, but what would the advantages of this?

Just wondering...
