1Bad402 Posted February 13, 2011 Share Posted February 13, 2011 Engine building question; Big block Chevrolet, do you need to use the 8 inch harmonic balancer when a 11 inch clutch/168 tooth flywheel is used. An old time builder said you can use the smaller harmonic balancer but engine bearing life is shortened. Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted February 13, 2011 Share Posted February 13, 2011 A lot of 402s did not use an 8 inch balancer. Whatever you do make sure that you use a internal balance unit with a 402 and external balance with a 454. Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted February 13, 2011 Share Posted February 13, 2011 a 402 is internally balanced, a 454 is externally balanced and require special balancer and flywheels that are weighted for balancing Quote Link to comment Share on other sites More sharing options...
