I have installed a 1990 5.0 HO that I got from a reputable junkyard saying it was a good running motor. This motor came out of a Mark VII. I installed this into my 68 Mustang with a T-5 transmission. I had to buy a flywheel. I have already had an issue with the parts house giving me the wrong starter and now I want to make sure I have the right flywheel. The car is idling with a bad vibration and it also has a terrible metal on metal knocking sound. Could these 2 be related or are they seperate issues?
I am not sure if the weight on the flywheel is 50oz or 28oz and can not find anything conclussive on the internet. I am trying to get out of pulling the motor again but it is looking like I will have to.
The flywheel has this info on it:
RF-E1ZR6380-A2A and EZ6-AA
I have read that the E1 represents 1981 meaning it could be a 28oz or 50oz but I may be wrong. It is a 157 tooth flywheel
The harmonic balancer is part # E4TE-A3A
I am hoping both of these are 50oz.
Here is a link of the motor running. It is from a Droid phone so not the best quality but the video sonds the same as real life. The smoke is from oil and crap on the exhaust headers.
The sound did go away for a little while and then came back, the vibration never went away and at one point, it sounded like a rattle can (like the metal was moving around inside, maybe a foreing object?)
Thanks for any advice. I am trying to get my stepdad to come listen to it but they live an hour and a half away and I am trying to diagnose it first if possible
