I have a slight vibration in my 67 Nova! Just converted to a M20 Muncie 4 speed! nothing before conversion. new clutch,new pilot bushing, resurfaced the flywheel new trans mount,new u-joints! afraid to get on it because of the vibration. any thoughts to what could be causing the vibration? Rich
 
Am I to be assuming it was an automatic transmission BEFORE, you swapped
and you've swapped an old torque converter and flex plate for a new flywheel & clutch pressure plate
and the assembly was never balanced?
 
That's right! can I have the flywheel and clutch balanced? or is there something that needs to be done? it's a stock 67 283 engine! thanks for the help! Rich
