Hi all. Well I like my blazer, but I am not sure that the 350ho is enough. I am thinking about putting in a cad 472 that I have built for my work truck. I think it would be a good combo for 3.73s and 33 or 35 in tall tires. Then I can swap in my 350 330hp into my work truck, which would probably get better fuel economy than the 472. Plus I am driving my blazer as my work truck right now since the work truck is down Im sure a 73 longbed 2wd with 3.07 gears will get better economy than the blazer too. so what all do you guys think, Should I do it?
