318 build up

I've read the comments on the lighter rods..... those who have actually beat on them report success. The comments about them looking light have all been from those who have not ever used them. So I am concluding they are OK. But I am sure I will get an earful of how they failed now! If so, please state if you put in new rod bolts, how much HP or 1/4 miles times, etc., so some context can be had for any such failures.

From what I have read, the heavier rods are only about 32 grams more metal....so they can't be THAT much stronger.....
