Which Flywheel?

[LANDC]

I am in need of a new flywheel (Manual Transmission ) for my 454 BBC. I know that it has to be an externally balanced one and all that, my question is would a ' Nodular Iron ' flywheel be as good or better as a machined steel one? I can purchase one out of the GM Performance Parts catalogue ( Nodular Iron ) for about a hundred bucks cheaper than a Cenerforce one ( Machined Steel ). I have exhausted all wreckers and racers and have not found a trace of a used one so I think a new one is my only option. Also, I have been told that cast iron ones can crack and or detonate/ fall apart with abuse. I am running 44's and on a good day I believe I am in the neighbourhood of 425 ponies, so naturally it has to stand up to some pounding. Has anyone had any experience with this? Which is better? I am not against springing for the Centerforce one, but a hundred or so bucks could be easily spent elswhere on my ride. Thanks.

With my built 454 I used Hayss 30Lb flywheel w/ Luk-ProGold clutch kit


My 454 is about 450hp & 550tq

So I have dropped the tranny out of the way and upon inspection I can see the ring gear isn't totally hooped. I will probably replace it seeing as I can do so easily now. I am running a 12.75 inch flywheel. It is from an internally balanced 305. I purchased a weight that is attachedto a plate that is sandwiched between the flywheel and the crank flange. The plate the weight is on has moved the flywheel away from the starter a little. Is this repositioning of the flywheel slightly back from the starter causing my problem? The problem being the starer sounds like it can't turn the crank over once in a while but always turns through, speeds up and starts.

Do yourself a huge favor and buy a new forged flywheel that is made for external balanced applications!!!!!

Your engine will thank you, and your legs will really thank you!
