Hello fellow mopar lovers I have a ?so I have a 1972 plymouth scamp fresh 360 mild build. Broke in the cam and it ran great but i never drove yet because i was still trying to tidy up other little task on the car....so i finaly took it for a spin around the block and half way through the drive I hear a thud sound. Now the car stayed running so I babyed it home. There is a knocking sound that no one can seem to figure out what it is. My engine builder says it's not the motor and the noise only occurs when I give it a little bit of throttle. Some say it could be the flex plate or the torque converter. So if anyone knows any info would be greatly appreciated thanks!
