Thread: 263 automatic crank insert???

  1. #1

    263 automatic crank insert???

    Just wanted to touch base with everyone playing with the straight 8's... I made the mistake of buying a 263 with a dynaflow to replace the 248 in my '40 Special... Now I am looking at having to get an insert made to hold the pilot bearing for the 3-speed... I am wondering a couple of things though...
    1. Is the machining in the 263 crank a uniform thing? Meaning that I could have the machine shop make a batch of these insert up for future use?
    2. Seeing that this is not a "NEW" problem, Has anyone out there already done this exact thing before me? If so, any suggestions?
    3. If the cranks are uniformally machined for the torque converter 'cone', Is anyone else out there interested in getting one of these inserts?
    Thanks for the help guys!!!

    You may well have another surprise lurking in that Dynaflow crankshaft. If I recall correctly, you can't just bolt a manual trans flywheel to a crankshaft from an engine that had a Dynaflow originally installed. I believe the diameter of the bolt pattern is slightly larger on the manual transmission 263 cranks than it is on the Dynaflows. Have you been able to bolt your 248 flywheel to the crankshaft?

    OUCH!!! Nope... I haven't tried to put the flywheel on yet, BUT it doesn't really suprise me at this point!!! REALLY starting to wish I had my own machine shop!!! Thanks for the heads up though!!!
