Will this flywheel work for a ZZ383?

http://cgi.ebay.com/ebaymotors/Centerforce-BBC-Flywheel-NEW_W0QQitemZ140225652781QQcmdZViewItem

Will it need to be balanced?
I have a Centerforce 2 11 inch clutch to run with it if this flyweel will work.

No you need a flywheel for a One Piece Rear Main Seal Small Block. So when you order your melonized gear for your distributor order a new flywheel also. What intake are you buying a RPM Air Gap?

Dave

Yes, a RPM air gap. I have a 750 Holley vac secondary I will try on it.
Are you saying, that any small block one piece rear main flywheel will work for my 11 inch Centerforce 2?

As long as it is the bigger flywheel for the 11" clutch, yes.
The smaller flywheels are for the 10.5" clutch.
Dave

Do you think this one will work?
Thanks

You don't want a 383/400 or a 454 flywheel for a crate 383. The flywheel you want should be for a one piece rear main and be counterweighted. Same as the flywheel used on a 350 ZZ engine. An early 400 and stroker 383 (350 block 400 crank) use a two piece main and are externally balanced engines. The GM crate (86 and up one piece rear main engines) are called internally balanced engines but because the flange was taken off the crank to facilitate the one piece rear main seal the weight was added to the flywheel. Thus the confusion of internally balanced or externally balanced. The aftermarket makes all types of cranks that can be internal or external for the same engine! Be careful!

That one is for a 2 piece rear main seal also.

Thanks Jim,
Does this mean I need to have the flywheel balanced after purchasing the correct one for the one piece rear seal and counterwieghted? Do you carry the billet type flywheel I would need?
Thanks,
Dan

You don't need to rebalance these flywheels as they are at factory spec.

If I were you I would use a 168 tooth nodular iron flywheel from GMPP. It's cheaper and will withstand high rpm and is great for the street. It's just not SFI approved for racing.

What about this?

No. Not LS. Won't fit. Just go to the dealer or Summit and buy the correct flywheel. They only come in steel or nodular iron and the choices are on my previous post. Some other choices are Hays and Luk or go to aluminum. If you want good street performance stay with a 30-35 lb. steel or iron. If you buy the wrong flywheel on Ebay it will only cost you more money to ship it back, that is if you get your money back at all.

Jim,
Just to let you know I will be picking up a GM flywheel at dealer tomorrow. Center Force web iste says it really does not matter what flywheel you use with there clutches. Also guys at GM tell me that the wear factor on the two flywheels (billet or nodular) basicly the same.
Thanks for your help.

this is the problem i ran into. Got a flywheel for a 400 crank because i have a 383. instead i needed a 350 flywheel and i wouldnt have had to have the flyweehl balanced... BUT i just got mine balanced and it worked out.

Dan
Glad you sorted this out. I'm using a nodular iron flywheel in my 450 HP 350. I don't turn it much past 6500 and it's fine. With a flywheel, if you don't know where it came from it's better to buy new. Lots of guys buy flywheels at a swap meet only to find they have been machined several times and are too thin to be re-used. If the shop doesn't measure the flywheel before and after machining you may find out the hard way that it's below acceptable limits when the damper springs on the disc are dancing on the heads of the flywheel bolts!:confused: We deal with balance issues every day and I can tell you with the number of aftermarket cranks and crate engines out there it's easy to get confused.:confused:
