will a lt1 neutral balanced flywheel be okay mated to my 305 tpi

 

What year is the 305?

 

A stock untouched unmolested LT1 flywheel is the same balance as a 305 or 350 from 86 up. Bolts right on.

If the flywheel's balance has been dinked with, though, all bets are off. You'd have to check with wohever sodomized it, and see what they did and either get them to undo it or get someone else to make it back stock, or you'd have to get another one.

 

you will get one hell of a vibration it you run an neutral balanced flywheel, well with a standard balanced engine.

 

305 is 92 flywheel is slp steel billet for internal balance lt1

 

Still applies. "Steel" doesn't matter. Assuming of course, that the flywheel is stock, unmolested, and untouched.

Brand names and "internal" are of no use.

If it's stock and untouched, it will work.

If it is not stock and has been worked on by someone making it into something non-stock, whether they throw the word "internal" around or not, it will NOT work.

This is not all that complicated.
