Hi guys. I have a mint'58 GMC 2.5 ton flatdeck. The original 270 has bit the dust. I have a donor 350 small block on hand. Will this bolt up to the original Muncie 4-speed (Muncie SM420)?
The truck also has the original rear end. The 10 bolt single speed with a 5:43 ratio. Rear axle is 10 stud (#2367009).
To get better highway driveability and fuel economy, does anyone know of an 'easy' gear ratio swap? Would it be simpler to get a late model rear and swap drum to drum? Would a transmission change be a good option, such as an R700, or..?
Finally, my last question, does anyone know the easiest way to put power steering on this truck. What would be a good donor unit ?

Many Thanks,
