347 engine vibration
I have a 347 in my 66 Falcon. Problem is the engine vibrates from 1500 up. I checked the balancer and it is a 28oz. I replaced it with a rebuilt stock and it still shakes. I checked the weight on the flexplate and it appears to be a 28oz. Doing the math it came out to 28 i should say. I am running out of ideas. The motor mounts are good and it is not misfiring. It is running perfectly. It is driving me nuts. Any suggestions? I haven't turned the torque convertor so see if that helps yet. It is a TCI 3000 stall. I thought it was the exhaust, but had that done too. No change. It is driving me nuts and i really dont want to yank the engine. Any thoughts?

Did the stroker supplier say 28/28? Note the discussion here that suggests some are 28/50:

More than one forum comment said they are never 28/50, always 28/28 or 50/50.
Lots of folks with questions though. Common answer is take it apart and have a shop balance all the parts.

I have no idea what crank is in it.I have come to the conclusion that it is a zero balance crank with a 28oz balancer and 28oz flex plate. The engine has to come out regardless so I am just taking it in to have it balanced. Looks like I just need to buy a flexplate because I can take the weight out of the balancer. I am pissed i didnt notice it when I bought the car.
