I've got an offset ground small journal rod 400 crank, i believe 3.875 (suppose to be a 421ci when i'm done). ANYWAY do you guys know if this will need a special balancer and flywheel. The crank has also been knife edged and drilled in certain spots......basically a lot less metal than a stock 400 crank. I'm just wondering if a stock balancer and flexplate will work, or do i need something different.
Thanks for your time.
