    Art Carr is about the only place you can buy one, when I did my Cobra I called B&M and they don't make one anymore. MIne was a 141 tooth 50 ounce flexplate for $130 and I had to grind the cage around the input shaft of my started to clear the weight. I'd never do it again, from now on if I were to use a roller motor i'd just use a T5

    take your crankshaft, Harmonic balancer, flexplate to a machine shop

    be sure you get a 50 oz balancer and crank also they can match your parts balancing and blueprinting also some shops like you to carry the pistons and rods

    ive heard this question come up a million times and answered with many arguements..it is a fact you do not need anything but a flywheel/flexplate
    to have it re-balanced from 50 to 28 or vise-versa.. if you get someone
    who says they need all engine block internals, you got the wrong guy on the
    job.
    EXAMPLE
    its a fact ford made only two PRODUCTION type 302 balances 28oz and 50oz.
    ford did not make a different 28oz balance for me and a different 28oz
    balance for you..many reputable machine shops can do this procedure
    with their eyes closed, and well under $100.00
    commonly they charge $60. which is about one hours labor..
    i have in my garage a 50oz (balanced) to 28oz and could take a pic of it
    friday night..
