OK, the more I read, the less I know about what harmonic balancer to get for a 1969 350 hp car. NCRS says:
300 hp= 6"
427/390, 400hp= 7"
350 hp, 427 solid lifter= 8"
Simple enough? Every online catalog I read had different/conflicting/inconsistent info. 350 hp is never listed with 427 engines. 69 is lumped in with other "performance" 350s and with smaller HB's. 65-69 8" balancers only show big blocks. Part numbers have been 12555879, 3870325 , 3860010, and ???
Anyone have a line on exactly what goes in the 350ho, and maybe even part numbers or, <gasp> a place to get one???
