I have a 327 short block built for the future (68 cam)??? I had it all balanced with the harmonic balancer and (automatic) flywheel. If I changed my mind and wanted to put it in my 55 car that has a four speed what do I need to do to be sure the flywheel works. When they balanced everything the first time they wanted everything, do I just send the speck sheet with the std flywheel???

Thanks
