I did once and was sorry about it as soon as I started the motor for breakin as I was expecting to listen for various engine noises which were all masked by the gear drive. There are places for them and reasons as well, but not in my humble opinion, for the average engine that may see occasional strip duties.......

most all out race engine use belts or chains . top fuel and a small hand full of guy s use the single idler gear drives . not the two gear idler type. all the race engines i build for my customers get a belt or a hi quality billet gear set like Rollmaster timming set have used this chain setup many times on engines with over 250 on the seat and open past 700lbs .on valve springs with no failures of chain .. no engines i build for anyone will leave my shop with a PJ gear drive there alot of bad things they added to a engine that i will not get in to .as i have in the past on here
