[67ChevyRedneck]

Got a little bit of disappointing news today... the motor in my car is not original to the car, nor it is even a 289. The block info is above the starter, so the only way to see it is to remove the starter. The block is a D10E-6015-AA which translates to:

D = 1970
1 = 1 (which makes it 1971)
O = Torino/Fairlane
E = Engine
6015 = engine block
AA = 302

So poo. The block has a "Remanufactured by Ford" logo on the side, I was kind of hoping it was the original motor. Whomever rebuilt it put all the original 289 stuff back on it though as it has a lot of the "early" (pre April 1965, which is what this car would have come with) parts. They even reinstalled the plate on the intake that states the motor build date was March 1965. This probably means the motor has a little more power than I initially thought, but probably not by much. I'll have to research it.

The good news is I pulled the pan and replaced the rear main seal. I hope I did it right. Watched a couple of videos and used my Ford engine book.

I can still see cross hatching in the cylinder walls and the crank specs are 0.004 to 0.010 for movement, mine is right at 0.005. So that's great too. The motor leaks because all the seals dried out... likely from too much sitting. When I pulled the rear main it was so brittle it just crumbled apart as I pulled it out.

So, the rear main is replaced and a new gasket for the oil pan.
