I just acquired 2 new Blazers (haven't brought them home yet...) 1 is a 77 that has been rolled but it has a good 350/TH350/ not sure of tcase. The other is an 80 w/ a 350/TH350/NP205. My goal is to make the 80 into a reliable and fairly economically daily driver. For now I am planning on putting the 350 out of the 77 in it, leaving suspension stock, and running 31x10.5 A/T's on 15x8 Ralley's. Eventually it will probably get a 4" and 33's, but for now I am going cheap. Anyone have any brilliant suggestions for making a Blazer get good fuel mileage, ride good, and drive good?
