Vibrations on 68 Mustang

Hi Everyone!

My Boss decided to buy himself a nice Mustang 68, aaaaand that is where the problem starts :wink:.

The engine is running fine, but we have vibrations as soon as we run more then idle. Some sort of "specialist" over here in germany told us that we got one with a 302 HO engine. He told us that probably the problem is the flywheel or the belt bulley. But to be exact, we even don't know for sure if it is really a 302HO.

What do you guys think we should do to get these things into the right order?

Thanks for your help in advance.

Maybe a broken mount? Your specialist was probably referring to the flywheel. Older engines used 28 oz balance and newer use 56 oz I think. I'm sure one of the more knowledgeable members can help you I.d. you engine and how to insure the correct pairing.
Could be a lot of things, but I'd check the harmonic balancer. If it is old and the rubber has deterioated it can cause vibration, and if bad enough, engine damage.
The harmonic balancer looks brand new, but I don't know if it is the right one. Is there only one available or are there different ones so that something could go wrong in that case?
first thing I would do is find out exactly which engine you have. get the codes of the block, behind the starter is where you will find them. get back with the codes so we can go from there.
Ok, I get back to you as soon as I have them.

Thank you so far.

We took the starter out but there were no numbers as seen on google pictures.
All we have is a badge which sais 4d5 and on the block are the casted letters: FISE 88 (more guessed than you could read)

I provide a picture in a few minutes.

Crankshaft: E7AE-AA

I think that has to be 50oz?
