so what do you weigh

[GMC70c20]

I am in the middle of building my truck and am trying to get an idea on what it will weigh. It started as a gmc c20 with a 350, muncie sm465 and a full floater dana 60 as it was it weighed 4000 lbs even. I shortend the frame into a short bed, put a fatman front end under it a 9" with steel mono's and caltacs under the rear, I am going to run a lq9 (iron block) and a turbo 400. I did box the frame and replaced all the cross members with 2" tube I'm assuming the frame weighs right about the same as a stock shortbed frame. I took out the heater and am going to run a 20 gal aluminum fuel cell. I will probably run a figerglass hood also, I'm hopeing for 3400lbs but 3200lbs would be better. So what do you guys think?
