Its not a blazer, but Im buying a '81 chevy c10 2wd, all stock drivetrain. It has the inline 6 250ci... I need to know what tranny these trucks cam with, I know its a standard.. i think its a 4 spd with a really low granny gear for 1st. Can anyone help me out? Thanks guys

 

I believe it would be a SM 465.

Thanks for the info.... since you are the local wheels and tires mod, could you maybe help me out with some wheels tire combos for the said vehicle? I really want to put cragers on it... you know the classic ones. What would be a good wheel/tire size combo that would provide a nice stance and look good? Thanks!!!

 

Being a fullsize truck you shouldn'd have too many problems getting the Craggers of your dreams.

Up to a 33" tire should fit without too much trouble. Depends on the condition of the springs, you may have to trim some cancer.
