I have officially been infected. After selling my 68 SS 396, I am know the proud owner of an 81' Blazer. I just signed up for my membership card and sticker (can't wait). The specs: 4" susp lift, minor body lift, 12-bolt rear 3.73, 10-bolt front 3.73, 350, th350, silverado package. This is how I got it, but I have somemany plans running through my head I can't get any work done. Its great to be part such a great site and own a true american CHEVY 4x, none of that toy crap. Be Gentle, Its my first time!
