ANyone know where i can get a "single" roller timing chain that is -.010 undersized for an LT engine? Has to be single roller and undersized for the align bore already done.

 

Are you willing to use a stock set? If so there is a Cloyes oversized lower gear that might work.

 

that maybe what I have to do. Do you know a part number on it? I couldn't find the gear. Thunder racing sells an oversized gear. But they do not say how much oversized and have not e-mailed me back yet.

 

Oversized crank gear Cloyes S505
This is for the vented opti timing chain setup at least, not sure if it would fit the unvented opti setup chain. The difference might only be the upper gear on the early timing set I just don't know for certain.

 

thanks for the info. the lowers should all be the same. but it doesn't matter either way for my set up. the car has an electric water pump and I'm going back to a single roller to convert to an LSx computer and get rid of the opti. If I could find a undersized single roller for a roller cam motor I would just buy it. but can't seem to find that either.
