I have a '97 LT1 and I am changing the timing gear set. I bought a Cloyes set but I just noticed that the gear that goes on the camshaft is solid. The OEM gear had slots cut in it. Of course this means more rotating mass but is this good or bad? Bad for HP but good for more consistant timing???? All of the sets listed on Ebay show slotted gears. I know the LT4 (which uses a different chain) is solid. Any ideas?

I don't think solid or slotted matters, but you need to make sure the cam gear has the teeth to operate your water pump drive (unless you have an electric water pump).Rob B 95Z A4 Tech Page (Part numbers / locations, how to's, schematics, DTC's...) Home Page - shbox.com

and the amount of mass between the slotted and solid one is so minimal that a gallon of gas would have more of a affect then that would2009 Honda Civic EX- the daily beater

Rotating mass is a lot more significant than dead weight. After looking at the "solid" LT4 Extreme Duty cam sprocket, we cut 5 slots in it. GM increased the mass of the LT4 set to address some vibration issues. The mass isn't needed with other setups.Fred
