loud rattling noise when idling.
NO it will not FIT.
To my knowledge the only small block flex plate that doesn't interchange is the small block 400.
NO.
Should be able to remove the inspection cover and look at it.
Vibration, Clunking noise, starter not working correctly.
Probably a bad flex plate and ring gear.
No. The balance is different, the engine will vibrate.
on back of engine behind the flex plate.
Doesnt matter, the flexplate can be installed either way..
A automatic has a flex plate and a tork converter.. A manual trans has flex plate and fly wheel...
remove engine or transmission replace flex plate (flywheel).
