Somebody school me on 2V balance

[BIT]

I replaced the motor in my wifes 00 GT. It came with a Windsor, I went with a Romeo. Motor came from a 00 Expedition. Ever since I started it, it has had a vibration. I have asked this question before and many helped. I took it apart today to find that the flywheel I put on it seems to be wrong. I got the flywheel and clutch from a 2001 Mustang (new). The flywheel seems to weigh more than the Windsor one. The Romeo one seems to have a counter weight and thicker than the Windsor. I have swapped balancers between the Windsor and the Romeo and made no difference. Its obivious I have the wrong flywheel balancer combo. I need help to figure out what I need. Thanks guys!

Or a clutch issue. Like DOWEL PINS or even improper torque sequence can cause a vibration. To my knowledge all of the modulars are the same balance, hence the term modular.

Call Noah at Dallas Mustang, he will answer any question you might gave about clutches and transmissions.

the flywheel on the windsor should be a 8 bolt and the romeo is a 6 bolt

All the modulars are zero balance, there shouldn't be any weights on the flywheel. Only 4 flywheels for all the modular motors, 2 size clutches and 2 bolt patterns.

10.5 and 11, 6 and 8 bolt
