How can a crank get balanced without the rods,pistons etc?? it's done all the time. all you need is the weights from the other components. obviously, without those weights it's an exercise in futility at best.

I think superstock said it best about the "balanced" crank shaft w/o other speed parts Well I hate to admit it but I ll check my weight between pistons, make sure they work together and go ahead and strap it together. The 1.5 point gain in compression and the ability to use my new heads is going to be worth the risk of beating the bearings out and having harmonics. Anybody deny me that? Besides, gearheads live in a world of broken parts! 1973 Charger, former SE, former auto I'm not trying to be difficult, it comes naturally....
