LOL ... I'm spending my kid's inheretence.
Not really, I really shopped around and got a couple good deals on these parts, the aluminum heads are only about 20 pounds lighter than the cast iron, each, but the Big difference in weight back in the bilge area are the exhaust manifolds, the cast iron set weighs 160 pounds, the shipping weight for the aluminum set was only 54 pounds, bolts, risers and all, so, with all the lighter stuff added up, I have taken 200 pounds off the motor by using this stuff. I am searching for an aluminum flywheel ... we'll see, thats a nother big weight issue, the one that came on my vortec weighed 47 pounds, the one I've been running weighs 34, but I haven't found the weight of an aluminum one to compare with yet, I did run a flex plate first, but it made the cam kick the gears in the drive too hard, when I removed the flex plate it had a crack in it about 3" across.
