Any one use the 440 source flywheels

The 360 I built required the balanced FW, I took a zero balanced used unit from a 318-340 and had a machinist drill the three holes in the correct spot. The specs are in the Mopar Performance book, Chassis one I believe, work like a charm,,,,never an issue. But if you have your 360 now zero balance....bolt it on and go with a zero balance FW
