I love my truck and want to buy the correct parts. Parts - fuel pump, fuel and vacuum lines, and other stuff I can't think of at this time. The casting numbers are 3738307 on the block, 3836848 on the head, and FI223A stamped behind the distributor.
The truck part is a 48 3100 frame, cab, and bed. The front and rear drive train is 53 3100, and I have installed a dual master cylinder and 3.55 gears.
Now, for the engine I have noticed that the engine parts numbers are divided into groups. I would like to by these parts from the correct year group to maximize my engines potential and would appreciate all your advice.
Again, I love my truck and it is my daily driver.
Thank you
