Hi All,

What sources do you know of for getting adjustable cam sprockets for the A-series engines?

I think that being able to adjust the cam timing is a darn good thing for setting up a hot street or race engine for maximum flexibility.

I was drooling over the cam sprocket and front cover with the access cover on the Pit Road site and had an idea for modifying the front cover to support the adjustable sprocket.

There is a company called Front Panel Express that is on the web. They have a free cad program for download that allows you to design flat work including blind holes and blind tapped holes.

As a price test I layed out a 5" ring with a 4" hole out of 4mm aluminum including 4 tapped M4 holes for the base and a matching cover also from 4mm aluminum. The size is a total guess but gets in the ball park. After a quick trip to the garage the parts should have been 4" in diameter. I'll stick with the over size parts for now just as a demo.

The estimated cost for the parts was ~$24.00 for the cover and ~$31.00 for the mount ring.

The ring could be tig welded to the front cover or for a cheaper route you could have blind holes done in the back side of the ring and hold it to the front cover with small screws from the inside of the front cover. Use your favorite gasket goo or JB weld for the sealer.

I think I'll give this a try after I get some accurate measurnemts on how big the parts need to be and actually get beyond the parts collection stage of the engine project.

Haven't been too excited to get the big engine built untill the chassis is properly setup. At this point the car does not do a good job of putting all of the screaming 45 horsepower on the ground exiting corners, somthing that will change in the near future as I work out the front end geometry and get the front/rear roll stiffness dialed in...

Ok, I'll go back in my cave now. I just get in trouble when I start thinking...
