    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

      @Joe-xj2tb looking at the front of the engine, it would be clockwise . Thanks for watching !

      Rotate clockwise until it stops and then counter clockwise until it stops. Top Dead Center is halfway between the two marks (where it stopped both times).

    At 1:24 in the video I meant to say bottom dead center. Firing on #4 puts the #1 piston at the bottom of the cylinder on a SBC

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

      That is correct ! This video was just covering ignition timing . Maybe I will do one on cam timing in the future. Thanks for watching !

    I just use a pressure tester and crank the motor till I get the highest reading

    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.

      My balancer is 6.75 inch. The distance between the marks depends on how far the piston stop goes into the cylinder. It really doesn't have anything to do with the size of the balancer. Just turn it both ways until it stops and measure between the marks and divide by 2 and that would be true top dead center. Thanks For Watching !

      I'm sorry, that one is an 8 inch. I was thinking about my 327 in my chevelle. The one I did the demonstration on is a 350

    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

      If you remove the spark plugs, you should be able to turn it easier. You can also turn it with the flywheel or if the pulley is removed from the balancer, you can put 2 of those bolts in and use a large screw driver or pry bar to turn it.

      Thats because the engine rotates COUNTER CLOCKWISE!

    What balancer do you have,part number?

    • @briansummers8030
      @briansummers8030  8 หลายเดือนก่อน

      It is just a stock 350 balancer and I don't have a part number, sorry.

      Okay, thanks. I have a three fifty crate with an aftermarket balancer And lined it up like you did it the video.
      Just be nice to have the right balancer.
