Only if has 6 pac rods, or if it's a cast crank motor. Both can be identified by looking at the harmonic damper. Cast crank will have the words "cast crank only" on the dampner A 6 pac dampner will have a large section of weight added. It will be easily visible.Thanks - I thought that the balance was different for the 440 - torque convertor, harmonic balancer etc. Now I'm learning that there is no difference in balance right? I'm trying to solve a vibration issue. The transmission is the last hope.
He needs to verify what crank is in the motor. All he said is I have a 440. Could be a Frankenstein of parts like a cast crank motor with a forged balancer.Only if has 6 pac rods, or if it's a cast crank motor. Both can be identified by looking at the harmonic damper.

All transmissions are the same balanced. 0.Great - I will verify all of this tomorrrow.
So you most likely have a cast crank motor. However it still could be a forged crank motor with the wrong cast crank balancer. Not knowing what crank is in the motor is a gamble. You can roll the dice with the cast external balance converter and keep your fingers crossed.The balancer is "cast crank only" Could this mean a mismatch between the torque convertor/flex plate and the balancer?
Can I verify anything through the trans inspection cover?
Is the torque convertor specific to the 440 or can 383 and 440 use the same TC?
Thanks!
Thank you! I believe this is my problem. The TC has no weight. It is a cast crank motor.If the 440 has a "fat" harmonic balancer it means it has a cast crank, and will need a weighted torque convertor. The 383, 99% of the time has a non weighted torque convertor.
That is most likely a vibration problem.
I'll do that. Does the weight orient with something on the balancer? My TC has a drain plug.If you plan on changing the TC anyways..
I'd tack on the proper weight and try it..
