I need a new harmonic balancer for the 408 I'm building and have looked around and found several with the prices varying widely. Just wondering what guys here are running? It's mostly a street car with a few trips to the track per year so I don't need a $1000 balancer but it would be nice if it's SFI rated. What's your suggestion? Would like it if I don't have to spend over $150 but I'm not sure if that'll get a good quality SFI rated balancer. Probably not.
