I spent the weekend cleaning up engine parts and was hoping to get some clarifications on casting numbers. My knowledge is limited on this. If this is something that is time consuming please point me in the correct direction and I will do some further homework.
Here is a list of the parts:
Exhaust Manifold
C6OE-9431-F and C6OE-9430-F
Water Pump Pulley
C7OE-8509-D
Fan Blade
SC6AE-E and 913231 C70
Crank Shaft Pulley
C9OE-6312-E
Harmonic Balancer
C9OE-6316-D2 SS8
Timing Cover
C8AE-6059 A
If I'm understanding the casting numbers correctly the crank shaft pulley and the harmonic balancer are the only two 69 parts. Also doesn't the O (third digit refer to a 289 engine. The 302 and the 289 are close cousins correct, man I feel like I'm in college again.
