How to Assemble the Front of a Small Block
Sorry it took so long to get back.
If it is like the Edelbrock, you have three different keyways. Edelbrock machines the notch in the same shape as the stamped alignment mark on the crank gear. The cam gear only has one mark.
Now for Eddy, the round mark and round keyway are for "stock" or "straight up". The triangle notch and triangle keyway are advanced. The square mark and square keyway notch are for retarded.
You pick where you want to run it, straight up, advanced, or retarded and use that set of keyway notches and marks. Notice that the mark is at the 12 o'clock position, and the keyway for that mark is at about 1:30 position. I marked the sets and angles for you so see.
Here's the crank sprocket with the three marks and keyways:
Here I'm showing the mark's location to the keyway notch is about 30° or 1:30 position from the mark to the notch. Use these marks and notches together in sets as marked.
Here's how you set up the chain. The mark on the crank gear is straight up at 12 o'clock. The keyway for the crank gear is about 30° to the left. The cam gear mark is at 6 o'clock, and the cam keyway is at 4 o'clock. I like to set the chain up like this off of the engine, then turn the crank keyway to the 1:30 position, then slip thecrank gear on the crank, keeping the gear and teeth from jumping a tooth. I set thecrank gear, then turn the cam so the chain and gears line up and will fit together.
Here is what the package for the Edelbrock looks like:
Here are some of the instructions:
This one explains how to set up the chain and what the marks are for:
Here's the picture showing the alignment of the gears and chain:
This picture also shows the alignment of the sprockets, chain, and gears:
