64-69 Crankshaft Harmonic Balancer, Late Model 5.0, 3-bolt without Lip

64-69 5.0 Convertable Harmonic Balancer
Special Order

This is used when running a late model 5.0 engine with the v belt pulley system. New balancer. Made in the U.S.A

Original early 289 / 302 engines have a 28 Oz. balance. Late model 5.0 engines have a 50 Oz. balance. If you swap over your early timing cover and accessories and want to make the late 5.0 engine use a v-belt then you must use a conversion damper like this one. Using the late damper will throw off your pulleys and trying to use the original early damper will damage the engine!
