At 1:24 in the video, I meant to say bottom dead center. The piston needs to be down in the cylinder away from TDC so you won't be screwing the piston stop directly into the piston. Firing on #4 puts the #1 piston at the bottom on a SBC.

    Thanks for doing the video- Yall say the engine rotate clockwise wich is twards the right- my question is why are you rotating it counterclockwise

    Just wondering if that is an 8 inch or 6.75 inch balancer. I just did mine today with all new Chrome and Howards roller cam using a aftermarket 6.75 inch balancer from Summit. My marks were 6 7/8 apart divided by 2 is about 3.50 for center. I came in on my desk top computer to double check as they are further apart and wondering why. It is a 1976 Corvette.

  • When I turn the balancer counter clockwise the bolt is loosening and I can’t turning the balancer a full cycle? Any help so that the balancer bolt won’t loosen. I torque the bolt at 85 lb per ft but when I turn the the balancer the same way you do counter clockwise the bolt loosen

    The next step would be to verify that the camshaft has correct timing.
