2405 is crazy light. That's over 1000 lbs lighter than my GTX. I don't even think that's an achievable operating weight for my GTX.
Yeah 1000# would be pretty hard to pull out of a big old GTX... but it doesnt take much HP to run 8.90s at 2400#... I just talked to a cam guy tonight and he can get me another 100+ hp with a different grind so I will go with it and dyno the engine for the next owner
