What does a dressed big block weigh? 500lbs? 700lbs?

My old Merc catalog says: 454mpi = 886lbs, 502mpi = 965lbs

Sorry, that's the inboard version I don't know if that weight is including trannys.

Total weight w/ bravo 1 drive is 1,200 lbs.. so subtract whatever the drive weights, maybe 150-175.. just over a grand..

I remember that 1200 number from the merc brochures. Even without the drive the still sounds heavy.

I had a 572 shipped with starter and alt. (no ignition or carb ) shipped on a skid and the billing weight was 925 lbs.

It seems like my numbers were correct, but I still think it sounds heavy.
I had a 454" in a car a couple of years ago, and that motor was 700lbs w/o exhaust.

Well that's the reason! You're talking 454 and the rest of us are talking 540's and 572's! It's the extra cubes that are adding the weight!

Anyways, thanks for your help guys.
