Re: Blazer\'s best year
The 700r4 was improved somewhere around 83 or so. Older Blazers (73-82 or so) came with the 12 bolt rearend. That would apply to the even older models as well I believe. Somewhere around 83/84 they switched to 10 bolt rearends. If it was me, I would try for a late 80's early 90's. One, for the FI, and the fact that it proably has less miles. Then I would upgrade the axles as I went. Not sure if the years I mentioned before apply, but early models also came with a dana 44 up front....corp. 10 bolt later on. One thing to watch for in the mid 80's models is that a lot of them have 305 ci, 3:08 gears. I would shy away, unless it is just a really good deal. If you can find something better then go that route...your proabaly gonna want more power than the 305, and if you lift it, your REALLY gonna want better gears than the 3:08's.
