Harmonic Balancer Bolt
I'm in the process of rebuilding my 68 327. My question is, is there supposed to be a harmonic balancer bolt in the crank, or is mine broke off in the crank. I tried looking at it and since it was painted over, I couldn't tell.
I was thinking there was one, but after talking to a guy at work, he suggested I look into it more because he thought there was a certain engine that didn't. |

With the constant heat up, cool down cycles that a crank goes through, and the vibrations that the ballancer is supposed to reduce, and the RPM's that an engine spins (even with a normal driver) I would not trust one without a bolt one bit. |

Some were a press fit, 327 would be about the right vintage for that. You could try running a tap though it and see if the might be there threads are really there. Not sure of the bolt size but Moroso's web site will have it listed

That's what I was told: it might be a press fit

They are all pressed on, that's why you need a puller to remove, and an installer to install one.
I may well be wrong on all of them needing bolts, but i see no way for it to stay on, let alone stay in the same position. |

Ive only seen a few 327's that had bolts to retain the balancer. The vast majority of 327's weren't even drilled for the bolt from the factory much less tapped . I even had one early 350 that wasn't drilled for the bolt. Ive never seen a 283 that was drilled for the bolt. It was a learning curve in the early years of the small block. Remember the 265's didnt even have an oil filter .
