Roll Master now makes a timing chain set for these motors.

Heres the part number & Gear

Picture of chain installed

I knew it could not be perfect but minor adjustments can fix. Notice where the chain is dragging on the back of the cover on the upper right side. These raised supports can be cut down 1/16 to give clearance. Because its on one side, it probally is just a casting flaw in the cover. I am going to clearance all three sides to make sure we do not throw any metal in the engine.

This is way better than the GM chain. I got it from Scoggin Dickey for a buddy of mine I'm helping build HP500's. It is tight.

These will go in mine next

I used a good Cloyes double roller in mine. I had to machine the cover to fit. When I bought mine several years ago, you could not find the timing chain covers to fit the Gen VI
I also had the cam button for the roller. Even machined down thin, I never had a problem with the cover after 3 years of running.

Thanks for the Info.

I have allread bought the Cloydes Hex a just for my gn 6 $123.00.I guess there better than stock and will be easy to degree the cams in.



Good luck Linster

I've got a pair of gen VI's to rebuild and the chains on both motors seem to be hitting the damper.I would make sure and check that clearance as well(they have GM chains).

I will look as well, I 'm not the fastest engine builder but I usually don't miss something. Crawling on a rebuild is better than blowing on the first run.

Built 2 motors last winter got my covers with timing pointer and cove from scott shaffirof racing in bohemia NY 200 apiece though

The chain is behind the cover . The dampener is in front.
Do you mean the dampener ring is hitting the cover . or the chain is hitting the cover???
