For anyone who is researching the Cloyes Original True double Roller chain: (or similar)

Crank Sensor:
if you have a 96-97 or any other that uses the crank sensor at the bottom of the timing cover, you need to get that sensor programmed out when you get your mail order tune. (I got mine done at PCM4Less) The sensor plate will not fit back on the crank shaft when you install the wider double roller.

You will also need to either obtain a 93-95 hub to make up the space difference, or make a spacer like I did from a 1 inch Inside Diameter washer, bored out to 1.25 ID and keyed (pictures below)

Chain install:
It is also much more difficult to put on the chain since it is more rigid and wider than the original chain.
1. Hand install both bottom and top sprockets and line up the markers without the chain.
2. Put the bottom sprocket in the oven for an hour.
3. Make sure the car is in Neutral with parking brake and you have the crank bolt installed and a wrench and correct socket near by.
4. Quickly put heated bottom sprocket on and slide it on halfway by hand using the key as a guide.
5. Hold top sprocket with arrow facing down and chain installed on it, and put chain around the bottom sprocket. You should be able to slip the top one over the cam dowell at this point, then gently tap the still hot bottom sprocket all the way flush with a piece of pipe and a hammer while sliding the top gear farther on whenever possible.
6. At this point the goal is to install the cam bolt which is directly opposite of the cam dowell. If the holes do not immediately line up, Grab the wrench and turn the crank just slightly so the slack in the chain is equally spaced on each side. When this happens, the holes on the top sprocket and cam should line up and you will be able to install the 3 cam bolts.

As promised, here are pics of my hub spacer washer:

 

Has anyone else done this?

 

yes same thing i did a few years ago when i put my engine together, actually i cut out the center of an old reluctor wheel like in your pic and used just the center, looked like your home made washer when done

many people say they have timing chain cover clearance issues with this chain set up but mine had plenty on clearance but i have a true LT4 timing chain cover, i dont know if there is a differance or not from a lt1 cover

 

I did a fair amount of grinding out of the cover for clearance, but I hear that the felpro timing cover gasket gives you more clearance also.

 

How thick is that spacer? It wont be as thick as the reluctor ring since the sprocket is thicker. I ended up making one about .060".
