Just checked my axle ratio...

[goldwing2000]

Bought my Blazer back in November but just got it on the road earlier this month. I thought it had the 3.42 axles under it like my '80 K-10 but wasn't positive. It felt seriously under-powered compared to the pick-up but I figured it was just because of the 2" bigger tires.

Boy, was I wrong.

Was at the tire shop today getting new wheels put on, so I took the opportunity to do some axle spinning and check the ratio.

Yep, you guessed it. I'm stuck with the suck-ass GU2 2.73 axles. I'm turning like 1700 rpm on the freeway, according to the ratio charts. It's pretty sad when I'm thinking about swapping in my K-10 3.42s to gain some more power!

Oh well... I guess those will have to tide me over till I find a good D44/14FF 4.10 setup.
