Does anyone have the figures on what these engines weigh? I am curious as I had heard the 3.2 fully loaded was around 635 and a SBC was around 540 fully loaded. I would like to confirm this with facts and not heresay. So if you know the actual weights, post them up here please.

Scott,

I'll take a shot at this; approximate weights from memory:
Iron head SBC tall block = 585lbs
Al. head SBF tall block w/ pan, WP = 425lbs
4.6 Ford Mod. SOHC complete w/ electronics = 680lbs
Audi A8 V8 complete w/ electronics = 720lbs
Chevy LS1 complete w/ electronics = 390-425lbs
Before final install, I'll weight my LS1 to remove any doubt.

There's a lot of conficting information floating around, so feel free to dispute.......

EJ25 Subaru engine - 275 lbs

EJ20 (turbo) is probably the same.
