Which cummins?

[Fla 66 cuda]

I not badmouthing 24 valve engines just my opinion have heard some complaints from fellas that traded in their 12 valves for 24 valve engines [mileage,power ect]. Once you go diesel you'll never own a gas truck again trust me, i personally won't own anything but a dually they are a P.I.A. kinda, can't go thru most bank drive thru atms,kinda wide for some streets,more tires to buy but there ain't nuthin i'm afraid to haul i fell in love with duallys back in the 70s and always wanted one. I want another to slam,shave completely customize.
