Timing Gear Drive

I have one on my 340 duster and I'm very pleased. I twist this engine to 7000 rpm with no issues. I was impressed with the quality of this peice. It is an easy install requiring one hole to be drilled and tapped, and a bit of clearanceing of the timming cover at the bottom driver side. This peice is way better than any double roller chain, I have had. It elimated any timing wonder and I can tell this engine revs quicker.
