another k5 in the stable

[briank]

Just picked up a 1970 K5 from southwest Missouri, had been on craigslist for awhile. I was surprised that it has great torsion boxes, straight rust free bed sides, fenders and doors. Has some rust through on the outer rockers and floor boards. I plan on selling my 72 and driving this one as is after cleaning her out (nice curtains) and swapping interior. Has a v8 (needs a freeze plug) with 3 on the tree. This is one plain jane blazer. Ill picture the spid but only options are basically a pass seat, ammeter gauge, white top and some other minute things,even has a radio block off. Was sold new in Springfield, Mo where she spent all of her life. I dont think the engine is original though, trying to decode it as we speak. Any clues as to what engine these were born with if it isnt specified on the spid?
