Re: '72 K5 Blazer CST = Yet another Build

Thanks for the info. What are your plans with the factory front and rear gears, once you make the switch? I'm keeping it small block, so that would be to high of a gear. Thinking with the set up 3.73 may just be good.

I picked up .308 gears with a auburn posi carrier from the local junk yard, should be just right and with the power from the big block no problem turning the taller gears..grunt grunt
