I am building up a new LS3 based 427 short block to replace the old one with the rod knock. I want to go with the Cloyes billet timing chain set that has the C5R chain(isis). So the question is do you still need the timing chain dampner? My understanding is that they hand fit these so that a dampner is not needed.

Correct. The C5R chain/jsis G68V-2 60

The damper should be used with any chain.

What's the negative to running an ls2 style?

 

[427]

It stops the chain whip that causes damage from happening by giving the chain something to touch off on when the engine goes into the bad harmonic areas. Without it the chain will eventually fail if the engine is being used for performance/racing. How long they will last will depend on the damper used and rpm the engine operates in. Downside of using the fixed position damper is only cost.

I will just go ahead and use the LS2 style dampner. It is not that much money. Thanks guys.
