Seems like 90% of the big builds use a ATI. Never hear of any issues.
The pricing on them is interesting though. For ATI the Pontiac balancers are actually cheaper than the Chevy version. 370$ for ours vs 404$ for the Chevy.
Now BHJ which I am using the pricing is nuts. 663$ from BHJ. Nightmare Performance sells them for 515$. I bought mine from them last year for 440$.
The BHJ units from Nightmare are notched to clear power steering stuff for street guys. Direct fit, 4 bolt so stock pulley's can be used. He keeps a bunch in stock with precise measurements and sells them matched to your snout for proper press fit.
My engine is not really a race engine, do not expect to go over 7K.
