I'm up in the air on which route to go i know the doubles work well on bigger HP engines but come with their issues with oil pump and cover clearances and i know many highly recommend the C5R chain and billet gears so for a street driven 450-500 N/A car what one should i do? I think the price is basically a wash by the time you do the grinding to make the double fit!

 

C5r is plenty capable and with half the headache

 

Does anybody use timing gears anymore?

 

C5R chain

 

You can get the C5-R chain with Cloyes adjustable gears. Depending on which set of gears you get it's like 245 or 275...

 

A single chain such as the C5R will be more than capable of handling a setup like this.

 

C5r unless u r pushing some seriouse horse for the most part the c5r is plenty for everyone

 

Another vote for the C5R.

 

Sounds like the C5R is the clear choice!

 

LS2 chain is plenty.
