I have a late model 5.0 stroked to 347 I am going to put it in 66 covertible and want to use 66 style alternator, A/C and water pump. The harmonic balancer is 4 bolt so I need a pulley that has 3 grooves but has 4 bolts any suggestions as I am having a hard time finding one


thanks
Kerry

 

What Ive seen as the fix for this is a new balancer that has both pulley bolt hole patterns.

 

I had thought about that but I need to check as when engine was built machine shop had all parts and I don't know if any weight was removed from it. I would think it should be a stock weight 28 oz harmonic balancer. It is an after market balancer now

thanks

Kerry,

All 347's have a 28 oz imbalance.

 

Thanks that is what I thought so any multi bolt 28 oz balancer would work

thanks
Kerry

I have a Powerforce balancer and like it well enough. Both bolt patterns, ability to switch to a 50oz imbalance if needed, and it's affordable.
