STROKER BALANCING QUESTION

[83T-top]

So I'm thinking about buying a stroker shortblock and was wondering is there an advantage or disadvantage of having it balanced internally or externally?

Either way the assembly has to be balanced to the balancer and flywheel, right?

Don't know too much on the balancing part. I found someone selling one he said it was ran for 30 minutes and kind of working on some sort of trade between my long block and maybe some cash.

He said he has the balancer and aluminum flywheel it was balanced with. If I don't buy that from him, then I would need to have it balanced to mine, right?

How much would the balancing cost?
Thanks for any help guys.

They balance the crank to the weight of your pistons and rods. Internal balanced is more money because they need to use heavy metal to counter balance. Balanced to 28 oz. should be around $60. Balanced to 50 oz. I paid $80 because they need to remove more metal. DynoFlo in Henderson, NV. did mine.

Well, if you're planning some serious rpm you might want to go internally. If it's going to be a street motor I wouldn't bother. If it is a mostly street motor you might want to think about swapping the alum. flywheel too. It's more a high rpm piece. Any time you change parts in the reciprocating assembly you should always balance it unless you're SURE the parts weigh the same. Balancing cost vary, it depends on labor rates, time and how much metal they have to put in it. $200 should do it. Mike

If it's balanced internally, get the balance sheet and make sure it is what it is.
The positive with internal balance is you can pretty much buy any flywheel and damper that is "0" balanced and run it.

In my experience, balancing to 28oz is better than 50oz... it is lighter, and lighter is better.
You should still get the paper work and make sure it is what it is.
There are many who are externally balanced and stick an aftermarket damper and flywheel/flexplate on it without further balancing. I don't suggest it... I don't want to be responsible for your blown up engine either.
