They seem to be like double what a neutral balance flywheel goes for. .... what gives?

Almost 4 bills for one from MP

Are they gold plated or why so expensive compared to neutral balance ones?
 
If you can use a 143 tooth flywheel, O'Reilly sells one for like 90 bucks.

That is a problem because most people building cars would need an 11 inch bell which is not really that common for cars.

I have an OD bell ....10.5 inch

I think I would be trying to figure out a way to make it happen. With skills like you have, that shouldn't even be a bump in the road.
 
I bought mine from 440 source, they used to be $99, up a little since then. I have friends using these on stroker motors, with no problems. Can use as neutral balance, or weights come with for external balance, including the 360!

When you open the page it directs you to Brewers Performance website for balance weights for any application you will need.
 
I bought a Cat flywheel years ago... garbage. Buy quality not price... your legs depend on it.
 
Mine was about $179 or so with shipping...

Do you need SFI approved?

McLeod has a nice piece and they sell the counter weights to make it what you need.

Also there is a drawing floating around from Mopar on how to modify a stock neutral balance flywheel to 360 specs.
 
I thought I remembered the 440 source flywheel had the 360 weights I had to take off.
 
Why so expensive?

It's simple manufacturing economics: Chrysler made one 360 flywheel for every several dozen neutral balance wheels.

Add in the extra cost and machine time to make one.

There are many alternatives and as stated, don't skimp on flywheels OR their attaching hardware.

The blue print is readily available, ANY decent fly wheel shop can match the neutral balance wheels to the print.
 
Extremely important point! Attaching hardware. ARP bolts torque down to spec BY YOU. every time I hear stories about a flywheel breaking news is when someone wasn't watching their bolts and trying to change flywheels in between drag races or something like that.

Oh crap! I forgot the internet! I have to clarify myself of course it could happen 300 different ways but this is just the way I have heard of it happening...

there used to be a template to drill neutral balance flywheel to 360 unbalanced specs. I made a drill jig for it, long ago. IIRC, it required a pretty large drill bit, which would require a machine shop size drill press and taper shank drill.

That bump in the road might be a speed bump before the edge of the cliff.

A 143T flywheel, besides requiring a larger bellhousing, would move the starter out from the side of the block, reducing the area for exhaust in a place that is already too tight on an A-Body. This could mean (if you have headers) that tubes might need to be cut and re-routed, or a 1.5" exhaust pipe if manifold were used. Or, you could dump the TBars and go to a $3K coil suspension, freeing up room for the exhaust. Etc., etc.

Just a comment.
 
Could, might, blah, blah, blah......I mean, I agree with you but you never know till you try.

Wasn't racing... the only problem with the flywheel was the holes didn't line up! I plugged them and re-drilled them but I lost faith in the whole deal and tossed it in the scrap.
 
It's more money because it's a nuetral flywheel with more labor into it to get the balance right.
