Thanks for the replies. For a minute I thought that I may never get a reply. Nothing taboo about this subject as far as I know. A few Stock racers that I know carry a short block with them as a spare that is basically stock. I have asked this question to a few racers as well as an anonymous tech guy. Each person who answered had their own take on this. My guess is that if you are willing to take the risk with stock rods and pistons, that weight probably isn't the thing one should be worried about.
