One website writes that a fully dressed iron block LS is 580 pounds including the ECM, exhaust manifolds, wiring harnesses, etc.
That's what I found on bdturnkeyengines.com. I subtracted from that the estimated weight of the harness, PCM, accessory bracket, power steering pump, A/C compressor and its bracket from that since those stayed in the bay. Just pulled engine, water pump and alternator. Forgot about the exhaust manifolds. That's another, what, 20 lbs? But I also pulled the fans so that negates some of that which I forgot.
...Yeeeeaah. It'd only take a few minutes to do the balancing act Wes suggested. Narrowing it down to a ~4" range (width of my jack pad) would be plenty close enough. Plus it'd be kinda fun to do and interesting data to have.
