    Our member @myersmetalworks just posted this video about an 1 hour ago about checking
    clearances on a BBC rotating assembly.

    Well done video !

    yeah, a very well done bbc assembly video ,
    that covers a great deal

    I've always been rather amazed at the number of people,
    that assume you can just bolt , used and new engine components, randomly, together,
    without checking clearances and then expect the result to run correctly!
    I've seen guys order STANDARD BEARINGS and STOCK piston ring sizes,
    for an engine refresh, and re-installed a cam and randomly re-installed the lifters,
    having never measured or checked a single part...or how it fits,
    and then look shocked when mismatched components fail.


    a few related threads and as usual,
    the sub links contain a wealth of info

    He obviously has ALL the right tools and most of us will not have them, but it's important to
    understand what your machinist is doing if he is performing this operation for you.

    true enough, but the video serves as a good reminder on how many things should be done and basically in what order

    Thanks Indycars and Grumpy for the nice comments.... I really enjoy all the technical knowledge provided on this forum, and don't we wish it only took 15 minutes to check and correct the bearing clearances on a engine build... Wow... (The power of editing)
