    I have run flexplates in the past with no problems but on this Sanger project we are running GM 572/720 HP motor. It is internally balanced. It came with a steel flywheel which obviouslyI don’t want to use. Should I go to an Aluminum Flywheel or would a good quality Flexplate be ok?

    Looking at a 427 SBC fresh off the dyno and arrived at my door. Good numbers, 528 H/P 580 TQ. Unpacking and found they had installed an 18 to 20 lb flywheel instead of a flexplate? The old SBC had a flexplate, so I'm thinking that I might need to talk to the builder. But before I do that, for...

    I'm getting ready to by the PTO to connect to the driveline, and am planning to use a flexplate rather than a flywheel as it is lighter. Any reason I shuold consider using a flywheel?

    Does it matter if you run a flexplate or a flywheel? I know I’ve seen 'em both in flats and the motor that came with my boat had a flywheel. I’m finishing up the new motor and it sees like a flexplate would be lighter. Is there any rhyme or reason to one over the other? FYI: It’s just a...
