    Olson 12 qt v drive pan. Milodon pump. I have 1/2" clearance pickup to pan. Am I ok with this? I can close it up to 3/8 by using a washer under the stud but it puts the tube in a slight bind so I would rather leave it as is if ok at 1/2.

    Hi, I have a good (fresh) 454 that has been sitting for many years.... wow, like just shy of 30. Time flies when you're having fun. It was in a hooligan street truck, PO had to go to prison for a bit and I bought it hearing it run and it was strong. Never used it so I just started to...
  7. GN7 On the Dyno
    As to not to high jack a thread, back in '09 I was having bearing issues. I was running .0025/.003 clearance turning 7500 RPM with an Eagle crank. I found that the crank was bent and replaced it with a Compstar. I was also told my clearances were to tight and I was told to use .003/.0035. They...

    Hey guys, I bought a Mako flat a few months ago and am stripping powdercoat off all the rigging and anodizing it. The 12* casale was rebuilt, clearances set, and unused when I got it. Do I need to reset the clearances now that the powdercoat has been removed from the plate? If so can someone...

    I need to try a loaner impeller to see if the cut is right for my boat. The handhole is mid transom and I do not want to have to reseal the plates. The flywheel cover on the engine blocks the loader bolts from easy access. Anybody have a good method for checking wear ring / impeller skirt...
