I'm looking for tech specs for the 86 Blazer S-10 Tahoe edition. We inhereted this truck and I have now seen that it has some off-road prowress rivaling my Jeep. I have learned so far that we have a limited slip in back (C10 axle), an NP307 xfer case, and its the 2.8L fuel injected version. I'm loving this truck, but I'm interested in the ring and pinion sizes offered, the gear ratios, what front axle, ect. (Yes, I could look at the axle, but it's not here).
