First off I know I am going to catch hell for this but I would like to know anyway. Let me fill you in. As you can see in my sig I have an 80' and 86' K5 Blazers. One I have plans to wheel with. While the other I just want to look good, a fluff truck, all show no go. I just could not bring a nice lookin' truck into the woods and beat on it with a clear continence; I could do it with a Ford though nice or a beater. LOL I was planning on putting a 10 or 12 inch lift on the fluff truck plus a 3 inch body and some big tires maybe 38" or larger SS Boggers.I am worried that the truck itself could not handle such mods. It has a 10 bolt in front and a 12 bolt in the rear (I think, I really have not looked at it yet). So far I have been mainly concentrating on repairing the body. My main worries were... I was worried that the axels could not carry the load. As everyone knows with big tired and a lift other problems arise such as pinion angle and gearing issues. Any ideas on what I could do to fix the pinion angle? Could the stock gears handle all the extra rubber? Stopping, could I even do it? Would I have to buy a caliper conversion for the back? I am currently considering a 383 stocker to replace the 305. I thought that should be enough power to get the truck moving. Any suggestions?
