420A Harmonic Balancers

[iNoise]

Rebuilding motor using an 00-05 Neon block. Here are the Balancers from each block, the one pulled off the stock 420a looks a lot larger than the one on the neon block. Should I use a 420a Balancer with this new build or the neon one? Also the water jackets look a little more rigid on the neon motor, thoughts?

You may have problems with fitting the belt if you put a bigger one. Use the stock one just to be safe.
