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,
Chris 1955FirstSeries
