Re: Balancing connecting rods
there won't be any improvement at all if you just equalize the big and little end weight of the rods. If you're not going to have the assembly balanced in a balancing machine it's a complete waste of time jacking around with stuff like this. You could make the balance situation worse by taking weight off parts, maybe it needs heavier big ends to make the bob weight come out right?
If it were a flat four like a VW you could equalize all the rod and piston weights and then send the crank alone out to be spun. V-8's don't work like that at all.
