    Does anyone know what the bolt should be torqued to that holds the harmonic balancer on? What about the bolts for the crankshaft pulley? I have a SBC 350 and am putting on aluminum serpentine pulleys.

    Thanks :cheers:

    Centerbolt is 60 ft-lb IIRC. Never cared much on the pulley bolts so have no idea. I would guess 25 would do.
  3. I had two books.

    One told me 50 for centerbolt, other told me 60. So I just went with 55, I know very creative right :rolleyes:


    Don't recall the others.

    Thanks!!! I finally found my book (can't wait to organize the shop) and it said 60 as well.

    :cheers:
