Gen III Small Block Weight?

I've been looking around, and have seen all the way from 470 to 600.

What does your 5.3 weigh and what was on it at the time?

can't tell you numbers wise what it weighed...but my front end sat up atleast a half inch higher after the 5.3/80e swap than it did with the tbi 5.7/700r4 in there...

id say fully decked it weighs 100-125 lbs less than a first or 2nd gen.

in my experience, the weight difference is barely noticeable to a fullsize truck. i'm talking about hauling my gen I 350 vs my friend's 5.3L in the bed of my 94 c1500. in terms of offroad performance, it might make a difference. but i wouldn't expect it to be drastic. i add a lot more (i'm 190-195lbs) that that weight difference every time i take a seat in the thing and it doesn't seem to care when i have a few 160-210lb friends in there, either.

It appears that an iron block in the LS motors adds 93 pounds over an aluminum block, and an LS1 weighs a touch over 400. So I'm guessing in the neighborhood of 500 pounds, 65 pounds more than my next engine choice, not a huge deal.

5 percent difference in weight is pretty relevant in a buggy.

I read that completely wrong.
