i ran one in my 350 sonoma. it sounded neat. but they create a lot of vibration.
i actually had 2 of the 3 cam bolts fall out,and break the tabs off the cam bolt lock plate, and the cam buttom fell out.
i put a new button and plate on, lots and lots of lock tite, drove it some more, and sold it.
would i do it again.. maybe.

actually the design of a gear drive isnt what it thought it was. The rotating mass and friction of 4 gears is probably more than enough to make up the difference of two gears and a chain.
but still... I find 31hp hard to believe though, how much total HP was that engine making??

figured it had to be north of 500rwhp. sounds like a beast.

i think the main pickup of that 31 hp could be a difference in the degree of the cam in relation to the crank...

My dads 406 has a gear drive. It sounds cool. He's never had issues with it and it has probably 25k miles on it at least. I don't remember it having any vibrations but I could see how it could screw with an EFI car for sure.

I looked at them at one point, the engine builder told me that the noise they make
is evidence of friction, which means a loss of power. I did not press for additional detail
I just pretty much assumed that the man knew what he was talking about.
Granted, that was almost 10 years ago. Maybe things have changed.
