Default Normal or about to explode?

this is what my flywheel looks like:







Never seen any thing like this before, but I've only done clutches on small cars. The clutch disc looks great I was planing on just using this clutch, flywheel and pressure plate for a few more years, but I don't want it to blow apart and take out my tranny.

Do you think it will last? I won't be making more than 300hp and don't tow trailers often.

Thanks

Surely you jest! Get a new one, and you wil need a new clutch as well. Consider yourself very, very fortunate. BTW, did you remove them because of chatter? If so, you found out why.

man that flywheel looks worse than my last stocker when i burnt that clutch up. and a piece of advice from experiance go ahead and replace the clutch and flywheel with a unit that is a little stronger than what you need cause burning up clutches is not cheap.

Alright, does anyone have any info on upgrading to the 13" clutch and/or a good place to pick up the parts? I see the kits on ebay for $400-$500 but not sure if they are any good.

Can I just pick up the parts from my local parts store or are they a custom thing?

A few hairline surface cracks are normal and may safely be ignored.

But not those!

I suggest buying a double disc just because your never gonna have to worry about the clutch again but if money is tight likewise stated
