I was tearing down the Gen V Big Block this afternoon, and out of curiosity I weighed the heads and intake. The heads with valves and dirt still on weighs 76 pounds each.

This particular motor was a throttle body engine. I was amazed at how much the intake weighed when I pulled it. Putting it on the scale showed 58 pounds!

When I reassemble this engine, I am definitely going with an aluminum intake, most likely with a large 4 barrel. One day, I plan to get a fuel injected setup for it. I eventually will get aluminum heads for it, but I may use these iron heads at first in order to get the Vette on the road quicker.
