Okey so i need to zero balance my flywheel since i went from an externally balanced 3.8 to an internaly balanced 4.2. My question is, where does it and how much does it cost? Is there a way to do it yourself? (i need my car running by saturday night so this must be done asap, and being able to do it myself would save time) Im assuming you need some kind of balancing machine or something...Any chance a tire shop could do it seeing as they balance tire? i doubt they can but just thought id ask. Also if time seems to be too big of a problem i may just order an 01-up flywheel with overnight shipping. And that leads me to my next question. Would an aluminum flywheel be better than stock?

a machinist has to to the balancing, there is certain machines and procedures to do thie. as far a aluminum goes, it is personal preference. if you dont shift a whole lot it will work more in your favor. i almost bought on myself, but i talked to thepeople that doing my trans for me and they advised against it for right now.

Aluminum flywheels are for road racing, if your drag racing, a billet steel flywheel is what you want. I would worry too much about balancing it. If you do than you need to do all your clutch parts as well. I have never done a flywheel in 30 years, and I have build to me small block 350 / 327s that ran up to 9500 RPM..
