I was going to get one for my 360,but read all kinds of stuff about the harmonics of the gear drive eventually breaking the cam shaft,losing HP,and them being hard on the valve train.Any of this true?
All of it. Look for a gear drive on any modern race engine. High powered race engines use timing belts, bracket engines and circle track use top quality chains. Gear drives sound cool, but I really don't trust the cheaper product. There is a reason they are less money. What I fear is it's something we can't see. I use a decent chain or a chain and a tensioner on small blocks. JMO...
