72 mustang convertible.351c 4v bored and stroked,roller cam and lifters,still in process of restoration
Ok, im new to the mustang world so your info would be great. I have a 72 mustang that I bought in pieces, so I found a cheap 351c stock 2v with a fmx trans attached. I never seen or heard it run, I installed and it run great, BUT it had a crazy vibration off idle.so I pulled trans and found it had a new flex plate on it.it turned out to be a 50oz, I replaced it with a 28oz and bam, its fixed. Now I have been driving this for a year and have decided to swap to an AOD, Now here is my issue, the AOD came with a 50oz so when I swapped it out I left the 28oz on because I thought it would vibrate again with a 50oz, now it vibrates again like it did with the 50 oz, So my question is does the engine dictate what weight you need or the trans? sorry about the novel but just wanted to tell everything that has happened.
