so i’m building an ls3 418 stroker, and im debating on buying a double roller or a single roller timing set, the stroker will be N/A for a period of time but it is gapped for nitrous, reason as to why in considering the double roller, with that being said, i can’t seem to find a set that would allow me to still have my camshaft sensor on the cover, so would i need to relocate my sensor to run the double roller? or what would you guys recommend i do? thanks in advance!

 

A double roller is really not needed in an LS.
Back in the bad ol' SBC days it was needed to not only drive the distributor and oil pump, but also to overcome the friction of flat tappet lifters.
A good quality single chain is all you need

 

perfect! thanks for your feedback! so its a no go for a double chain? sorry if im asking so many questions, this is just the first time i’ve considered a double chain timing set

 

Consider it no longer....
