Hello everybody, well this has been an interesting journy. I am still trying to figure out why I am getting a vibration at the flywheel area, I suspected something was replaced so this lead me to look at the transmission ID # on the side of the trans, including the engine itself. I can't believe it took me this long to figure it out, but the ID # on the trans is AA-65, and the 429 engine has to be out of a 65 as the water pump lower hose outlet connector goes to the passenger side of the radiator not the drivers side like the 64 429 is setup!!
What really got me thinking, is I looked at the motor mounts, and the oil pan sump, not only do the mounts look newish, but the oil pan sump is front facing. This is why the oil pan was cut and rewelded in order to fit in the 64 X-frame.
Also if Jason is reading this, I can't use those flywheel covers I got from you as they don't fit the 65 THM trans. The mounting holes are different.
I have a theory, my 64 was made in July of 1964, so it's a very late in the year model build. Could the factory installed a 65 engine and tranny since the plant was getting ready to build 65 Caddys? Or do you guys think someone replaced the entire unit as the previous owner might of blew up the old one?
Or it could be that the transmission was replaced with a 65 THM mated to the 64 429 engine bell housing and this is what is causing transmission vibration?
I tried looking for the engine serial number by the lower side of the block and I couldn't find it.
I'll try again later on today, but if anyone can help lead me to an answer that will be freakin fantastic!!!!!
Gracias Mi Amigos.
