Re: '72 K5 Blazer CST = Yet another Build
a little something on the gears, my blaze came equipped with .373 gears and the factory posi in the rear. I have the granny 4-speed and on the highway I'm turning 3-3200 rpm (no Bueno)
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
