Hi:
We would be happy to help, but we need to know the size engine you have. See the list below (pic 1).
Pic 2 shows the info for a 5.7L. Most of them are the same, but I would rather confirm the engine size to be certain.
Let me know if the attachment helped or if it is a different engine.
Take care,
Joe
See pics below. Note, I highlighted cylinder 1 on the cap and engine block. At the crankshaft, there will be a beveled line that should be even with the TDC indicator.
