pontaic tips if you are going to use any type of preformance cam, you will need adjustable rocker arms. stock bbc rocker studs and nuts work with stock pontaic rockers and balls. harmonic balancers tend to crack in the keyway this also ruins the end of the crank. cam bearings can be an issue. they may be out of alignment after replacement. most pontaic blocks need align bore, extreme cases will need to pull out cap alignment pins and cut block parting face as well as the caps. poor factory machine work is the cause. some blocks will have poor deck finish. mill them. dont waste time with arp bolts in stock cast rods. cars that are driven hard need aftermarket oil pan and pickup. be aware of connector bushings between timing chain cover and rear water pump plate. good cam for mostly stock t/a reed 264/272 hyd. hope this helps stickboy 331
