[Chevelle-list] 283 balncer?

[chevelle292wagon dejazzd.com]

I have a 64 with a 283 2 barrel engine.
I plan to change over to a small 4 barrel and dual exhaust.
I thought it'd be nice to replace the pulley hub with a real balancer.
Which one to use?
Seems like the balancer for a 283 w/ 4 barrel should work.
Any suggestions?
Thanks
Pete
