Thread: 75 or 65

Tweet

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

Check the casting number on the block, see what it is. Denny gave you some good break down resources....

Okay thanks for the help guy's them are some good website's.I will have to look at the other number's on the block.Thanks Dave

Dave yes the blocks date code will have 2 dots under the 5 if it's a 75 casting. Also the casting number if the block has one will shed some light on the subject.
