tornado

I have seen a lot of older trucks on this site with alum wheels. Do you know whats in volved in swapinping from the steel?

What was the production run on that 237 engine. I was thinking about the Twin Stick Can that be swapped for an 8spd? Any thoughts Its just about time to start moving salt at night and I need to play during the day.

Thanks and have a nice weekend every one!

Yes it's a DM, probably a 685S. most common engine would be a 237 2 valve and the most common trans would be the six speed with two sticks.

From the pictures you can tell it has the 20k front axle. Can't tell what the rears are, ask him if they are either 5 or 6 spoke. 5 would be 38k and six 44k.

Pretty much a bullet proof truck, great as a site truck. If it has the Mack front axle( which it probably does) the king pins are adjustable.

As far as leaks, the most common are the valve covers.
