I bought a challenger with a 360ci/380hp crate motor. I am in the process of swapping the 727 to a a518. When I pulled the trans out,I notice it had a standard non balanced flex plate and a non balanced torque convertor. With all the research I have done, this motor should need a weighted flex plate.
I have had the car for over 12 years, spun it well over 6000rpm lots and never felt an unbalanced feeling ever. I am told if it isn't correct, you will know!
Does this make sense to anyone? can the 360 be internally balanced?
any thoughts or advise would be appreciated, thx....
here's the flex plate and balancer.........
That's not a "Magnum" flexplate on your engine,it would be more of a circular unit with a balance weight on it.The Magnum also uses less balance weight than the LA 360 engine. The LA engine has the balance weight welded on the torque converter.Odd that it doesn't vibrate or show any measurable wear.
