Hello! I assume this is a 1996 or later 5.7L engine? The fact that you asked if the cap needs to be parallel indicates that it is, but I want to make sure so I get you the right info!

OK, with the engine at #1 compression TDC (you must verify its on the compression stroke), you will need to line the distributor up. There is a dimple on the the distributor gear, and it must line up with the paint mark on the distributor housing (callout #3)



As you drop it in, the rotor will turn, and at its final resting spot, should be pointing to a "8" cast into the top of the housing. You may need to rotate the housing to get them to line up.
