Hello everyone, I recently purchased a 66 mustang that has had a 90-91 302 engine installed. There is some very heavy vibration felt in the car at 2000rpm and higher - even while in neutral. I've been told not to drive the vehicle as this shaking will damage the engine. Ofcourse the seller who sold me the car never mentioned this issue and I just thought it was how a old classic feels. After doing some research I have found out that either there is a wrong harmonic balancer or flywheel installed. In the worst case I may have a bad engine. I have gathered all the serial numbers off the engine (F16E) the serial number off the harmonic balancer (E4TE-A3A) and the flywheel (RF-E1ZR6380.) I also attached pictures of the serial numbers just in case I am not reading them correctly lol
If anyone has any knowledge about this vibration and can help that would be so greatly appreciated. Im hoping the harmonic balancer or flywheel is not correct and that I don't have an engine rebuild ahead of me. Any ideas?
