ProRace crank damper?

I have just order a ProRace damper for our 100M vintage race car and have a question. Does this damper have a pulley built in? We have converted the other various pulleys to the Dennis Welch narrow belt pulleys. Just not sure whats the deal with the new damper (have not received it yet), and the picture on the website is a generic one...... ANyone have an idea?
 
Mine was a tight fit, required heating up in the oven to allow it to slide on.

Like John said, the pulley is part of the 6-cylinder model.

Tight fit on the six cylinder is an understatement. I wonder how I will ever get it off if the engine requires a rebuild.

Looks like there's two holes on the front of the damper. Usually, these are threaded for a puller.

That's how I remove mine.
 
If you want to do it correctly, mic the snout of the crank. Then take your new damper to your automotive machine shop and have the opening honed out so that you have a .0010 to .0015 press fit tolerance (I don't recall exactly the #s off the top of my head but this is basic automotive stuff). Any decent manufacturer of harmonic dampers supplies this info with their product. Check out ATI Super Dampers. They are the best and they are made in the USA and I bet they cost less than the ProRace damper. The ATI damper and hub are separate units for the 6 cyl Healey.
