I would love to upgrade my rear end to 4.10 full-float, and spindles to accommodate the 8-lug wheels and brakes, slap some stock 2500 alloy wheels on it with some proper 10 ply tires, but my 15" tires are almost brand new and I am not looking to spend a lot or keep the thing for more than a couple more years. Your brake upgrade sounds perfect. I am a little confused about going to the older master cylinder. I've read that the one from a GMT800 is the way to go? I do not mind terrible mileage because I have a company service van and a loaded minivan with all the goodies that gets 25mpg while keeping kids occupied. The Burb hardly ever gets more than occasional use other than towing.
Jeff sent me the spreadsheet to do the 411 swap and I'm going to send it to him for a tune to be optimized for my application. I was thinking about just running it for a while with the stock Express 1500 flash. I mean it has the same engine, transmission, and axle ratio. It has to be right there, right?
I don't plan on getting started until the water that has been pooling up in my garage and freezing is melted and gone. I do want to get all the parts, tools, and info gathered up and ready. Maybe I'll try my hand at youtube. I will definitely start a thread and post up some pics.
