internal balance issue

I AM JUST WONDERING WHAT I SHOULD DO ABOUT GETTING ANOTHER SET OF PISTONS. THE CLAIMER SERIES SEEM TO BE JUNK.my engine is a 383 stroker with all scat equipment except the claimer pistons"junk".If i get a new set of pistons that are about 15grams heavier will it effect the internal balance job i have just had done.Thanks for you're time.

engine balance

If in doubt, I would go for another balance job, hower Im not sure 15 grams will make that big a deal, unless you are going to be turning some extreme rpm ( read that over 6000). Since most engines are rebuilt with out rebalancing and rarely do the replacement pistons weigh the same or near the weight of the origionals, and live long healthy lives, I dont think you would have to worry about it.

call the machine shop that did your balance and a couple others to be safe and see what the majority says.

balancing act

I would totally agree with Gone Nova, on that one. Preferably check with a couple other shops besides the guy that did yours in the first place.

I had bought the rotating kit from fast engine parts.com.It is a scat 9000 series crank with new balancer and flywheel.The crank has about 10 balance holes and i am wondering if i gave the new machinist the specs from the hines balance machine and the other sheet with all the bob weights and piston weights and a new set of pistons if they could balance my pistons with that.Thanks for you're time.

If you have the balance sheet, they should be able to match it. This will depend on how much weight they can take out of the piston (since the new ones are heavier). Please post back on what the shop tells you.

Or they could fill a couple holes drilled in the crank with mallory metal to balance it.
