Engine weights are very subjective; I have used the heaviest listing I could find to try and remove any chance of Bias.

I have to admit the LS6 is my favourite engine.
Just looked at the specs of the LS6. It starts off with "overhead valves, pushrods". I went for a visit to my antique dealer in order to find out what pushrods are. He told me that only in very old American engines these things are still being used to manipulate the valves. Anywhere else in the world the Overhead Camshaft has made pushrods redundant.
