I've had two 72 Blazers, inherited another from my Dad, a 70 K/20, and That 72 K/20, and I loved every one of them....the big blocker especially. I still have a '69 C/20 BB396 TH400 that my better halfs father bought in 1969.
Just a 1969 LS-1 out of an Impala. When the tranny blew, the body was so rusted out and beat up ( I used that rig as a tractor to clear our property) I sold it with the BB in it to attract more$$$$$$. I should have also replaced those slotted mags with the mud terrains also. Buyer wanted rolling chassis for his body.
I miss the ability of that truck to go much, much farther than the diesel unit simply because I had no real fear of wrecking it! That and the better ground clearance!
