i ran one of the older balancers for years on my 66 no problems. just wonder if on a 400 at 500hp or below if anyone thinks theres a problem with them...on a street strip type build?

ive got several later 68 covers and later 11 bolt covers but since i have a nice 64 cover/balancer/pulleys that seem to be garnering 0 interest, i was thinking of using them.

while im degreeing the cam and have the #1 piston exactly at tdc i was thinking of installing the cover and balancer and adding timing tape. since tge 64 cover has only a pointer i dont know any better solution.

i expect this 400 go need to spin to 6500+ with the 290b cam thats in it.
