I have get me a 74 Blazer and I wounder about some things, and this seems to be the right place to ask for that. It is a 454 bigblock in the car,did they put that engine in a 74 when they was new? And the rear axle is a 14 bolted, what kind of axle is that? I don´t find any numbers on it, Is it any of you how now what to lock or were to lock to find out what axle I have? I think I have a Dana 44 in the front, is that common? Thanks.
