My sister just bought a 65 thunderbird that has a 390 in it.I read the intake and it says D5TE,I know this intake is out of a 75 truck.But what I wanted to know is I am going to check under the engine on the oil filter mount and see if the engine matches the intake.When I look under there how do I tell if this a 75 or a 65?If I am right don't the 70 model FE blocks have to littel dots under the year.Like if it is a 75 it will have to littel dots under the 5,I want to find out if the engine is original for 65 with a wrong intake or is the whole thing out of a 75 truck.Also is the motor mounts, are they the same in every vehicle that has a FE block,probably not but just wondering.Thanks Dave
