It has the original Inline 6 cyl, 300 cu. in (Industrial) 4.9L engine. And, the entire truck, still has less than 6000 miles on it ! I'm a lucky guy. Paid $830 for it total, and it had never even had the oil changed yet ! Its for sale, if you like, make me an offer.... its hott for the trot. I've been offered $40 Gs, and turned it down. But I'd re concider something close, these days. It is a one of a kind, THE 1st, to be U.S.A. Street Legal. This truck GETS noticed & Attention Where ever its located. Kinda like a baby or puppy, ya know what I ,mean?
