This SBC weighs 489 pounds wet and fully dressed! Aluminum heads and other light-weight components. It dyno'ed at 420hp at the flywheel.
Don't worry; it's not going in the 911 - it's for another project TDB. It was just a hell of a lot of fun to build! I still like to threaten the local Pelicans, though - it makes for lively conversation.
I just installed a [fairly] virgin 2.7 in my car - only 40K original miles on the engine since 1977. THAT took some work and a lot of refresh!, but I'm pleased with it. BTW - according to the freight bill, (OK, how accurate do you think THAT is?) the 2.7 weighed 417 wet with the pallet, no exhaust. That's 72 pounds and 250 hp lighter! But that's not really the only consideration, is it?!
