At our local salvage yard there is a 55.2 or 56 Chevy pick up. I have a 55.1 with a 3:90 rear gear ratio and want to switch rear ends. I have been looking for a blazer 4x4 rear end but noticed this truck sitting up off the ground.

What type of rear end gear ratio would it have and would that be a better swap than the blazer.

I currently am running a 283SB with a 4 speed saginaw transmission and with the stock rear end pulling 2800 rpm at 55mph.

Thanks,
