rod weight ?

Rod,

I typically try to make all of them the same. Most manufacturers of aftermarket rods and pistons say that if they are all within 2 grams they are ok, but it really only takes a few seconds more to make them the same so why not do it 100%

The only exception I make is with aftermarket "H" beam rods. I do not like grinding off any of the ribbing on the bottom of those rods. Sometimes you can take some weight off the sides but sometimes it is impossible to make them exactly the same.

That being said, are you having the crankshaft balanced ? All of the pistons and rods can be within a thousandth of a gram but that does not make a bit of difference if the crankshaft is not balanced to those weights.
