Re: 383 question

Most 'cheap' strokers with 5.7" rods use an external balance and your harmonic balancer points to it being externally balanced so if I have to "GUESS" then it's externally balanced and you'll be needing a "400" flywheel. If he believes that the machine shop was the one that installed it and it wasn't installed by the guy that had it built then I'd take the chance on the 400 flywheel - a quick test rev really won't damage anything and if it's not right you'll have a nasty vibration upon a rev at mid to higher RPM's and you'll know right away that he'll have to swap to the neutral balanced stuff before really running it.
