I agree with GL Perry, Don't go with a Chevy diesel, unless its a duramax:-) They were oil burning pieces of garbage, in my opinion. Very doggy. I had one in a suburban, very poor. Theres always a powerstroke, which was ahead of its time until the duramax came out, but your probably gonna wanna stick with chevy.

1955 Chevrolet 210 2 door Sedan
a 30,000 mile UNMOLESTED original, now my daily driver! Original 6 cylinder with a rebuilt '66-'69 Saginaw 3-speed Overdrive. Synchro low! Otherwise, everything original down to the spare tire. Interior is like new. Needs paint, but absolutely zero rust.
