Hello everyone,

I'm currently working on a build for my 1966 Olds 425 engine. I have the block and rotating assembly at the shop now getting machined and balanced and we can hit neutral balance. I need to find a neutral balance harmonic balancer so if anyone has any knowledge or options let me know

Thanks
Mike

 

Scat 8022 or 9022. Both have removable weights.

 

I have an ATI, but be careful because they're available with Ch*vy and Olds (4&3 bolt) pulley patterns.

 

What about this balancer? It's SFI approved.

ATI is the best you can buy. You can even get them with the magnets in the shell for a crank trigger.

 

ATI is good but they run close to $500. While the Professional Products SFI approved one is $220.

 

You get what you pay for and you don't get what you don't pay for...

 

There has been guys who have had problems with professional products sfi balancers. Now I am not mudding the waters I have used three no problems. But I also am not spinning past 6,000 RPM. I did buy a quality neutral balancer from TCI for my next build in the wings. Will I buy the PP balancer again no!!

 

Everything Professional Products makes is a copy of some other companies product. They are reverse engineered parts made is Chinese shops who dont give a f**k if you motor self destructs, and you end up with a hole in you radiator or hood.
Hell, the intakes they made for Olds wouldnt even line up correctly, and needed machine work to be usable.

 

Looks like ATI will be the better choice
