RPM 1,190 Report post Posted December 31, 2020 A very unhappy motor. Don't do it. I had a 50 oz flywheel balanced to my 28 oz flexplate that had weight added to it when my motor was balanced. Cost was only $40. So if you already have a 50 oz FW it can be balanced to your 28 oz unit. 1 Grabber70Mach reacted to this Quote Share this post Link to post Share on other sites

JayEstes 172 Report post Posted January 10, 2021 This is an interesting topic. I'm curious what the reasons are for this? it obviously changes the inertia of the flywheel having 3/4 lb more weight on it near the extremities. But the weight is balanced, so it's not inducing side to side loads, jsut loads in the form or torque. But it's just an attachment plate between engine and trans, so those things should dominate the torque felt by the engine. What does this heavier flywheel do to the engine? Can anyone explain the issues it creates in more detail? Just curious. I'm not looking to run any experiments here. Quote Share this post Link to post Share on other sites
