I have the lt-4 extreme duty chain now.....what are all you fast guys running? Im guessing double roller, but do you have to do some grinding to the timing cover?

Cloyes double on my car with 200 jets, timing cover need a little clearancing. Dont forget you have to go to an e-waterpump for this setup.

I have an Ewp and when I finally get around to putting the cam in im gonna upgrade the timing chain to. Since to EWP eliminated the need for the cam drive gear (or whatever its called) I can run a double roller for a Gen I SBC right?

You also need the newer style vented opti.

I don't see why running nitrous would make you need to change your timing chain.

Nitrous doesn't add any stress to the timing chain though.

I meant if you're changing your timing chain, which he's obviously doing. Plus anything that is adding more hp and tq, should be adding more stress, to every part in the car. Not saying that it wont work perfectly fine on the lt4 setup, just saying it's an extra piece of mind. I dont think I've heard of lt4s failing, but the cloyes is cheaper than the lt4 anyways if you're changing one...

nitrous certainly does have an affect on a chain. especially if there is alot of slack. im building this motor with top quality parts and im not going to let a timing chain snap and send everything out of whack. thanks for the replies everyone. looks like im going with a cloyes.

N2O definately adds more stress to parts,thats another reason why you should only spray when the RPM is above 3000!
pistons
rings
rods
bearings
timing chain
oil pump
that's another good reason to have main studs,main girdles,4-bolt mains,splayed caps and or block fill..........

Nitrous certainly adds more stress to the motor, but you will pop a piston or blow a head gasket before you'll rip apart a chain.

How does it add more stress to an oil pump or timing chaing?

How does nitrous put more load on a timing chaing?

when the nitrous comes on it FORCES a cold charge into the combustion chamber to create a more volitile explosion.do you NOT think it would cause more stress in all moving parts.
when you hit the button the motor will have a SPIKE in RPM roughly 1000rpm

I know how nitrous works and I used to have nitrous on my car and I never had this instant 1000rpm spike when I sprayed my car. I'm still waiting for you to explain how it puts more stress on a timing chain or oil pump.

Where's the instant 1000rpm spike in this video?
