failed flexplate

Make sure the difference is something other than the name.

Building a 500 CI pulling motor, looking to make close to 1100 HP. I’m looking for suggestion for a crank shaft was looking at Bryant ,Crower etc.
Suggestions in who to use.

Crower, with the pendulum undercut counter weights....allows you to run lighter weight pistons / rods.

Wouldn't pulling get an advantage from the inertial weight of a heavier assembly?

For anyone following on fb, you probably know...aftervchasing some fuel system issues I unfortunately had the oem unit fail as well. The engine had been cranking easy, with no tight spot, but it kicked back. I may have to go CSR with replaceable ring.

Agree with you there. Hughes look about the same as Scat. Maybe they are better, but....

I had a customer that finally changed to ATI for a flexplate. Quite pricey, but zero problems since. I would strongly recommend.

Those ATI flex plates are nice and expensive .Hays has a heavy duty sfi flex plate available for about $110. I just bought one really thick and well made . I wish they made one for the FE though .Doug
