I made that mistake once and it wasnt pretty. I took out a normal internally Balanced 350 and installed what I thought was just a different year Junk Yard Motor. SOB turned out to be a 400 externally balanced motor and I used the original Flywheel and HOLY VIBRATION BATMAN IS ALL I CAN SAY
(what could I say it was 30+ years ago and I was young and foolish )

couper

283-427 uses the same flex plate, (except 400)motors are Internally Balanced
454 uses a unique Flex Plate (except Gen V & VI) motor is Externally Balanced
