Assembling my engine it's a 2009 5.3 running a ls1 double roller and a melting oil pump the timing cover has the cam sensor which I can shim out not to hit but there's a large hump for hold down for sensor I'd assume are you guys just trimming cover to get it to clear.

 

Was this posted elsewhere?

 

Double roller for bragging purposes?

 

Yeah you can just grind or mill away that spot.

 

How would it be for bragging purposes? You do realize a timing chain does more than spin the camshaft don't you? There are benefits to running a double chain but likely they also come at a price and not needed in a stock-ish application.

 

It USED to, but no longer does distributor/oil pump duty. It does spin the cam, lift the lifter/pushrod, rock the rocker, and push the valve open against a few hundred pounds of spring pressure X 16. A GOOD single chain can handle that in MOST cases.

 

I was thinking the harmonic dampening effect with a big cam and springs and then you have resistance to stretch over time. It will still be beneficial in those areas but not enough to pay for the weight penalty incurred, I still wouldn't say running one is a bad idea just not needed in his case.
I'm running one on my 408 for that very reason, I don't run a damper because I run a Hub/cog pulley for a blower so in my case I will see the benefit.
I still not sure how it relates to bragging lol.

 

Run a dampener if concerned about chain throw/stretch....and then use a single.

 

If you're referring to me, The parts needed to run a damper with the blower weren't available when the build was configured a few years ago and I'm not going to spend a couple grand to redo it now.

 

I was referring to OP

 

OP

You have to grind the cover down in that area for it to clear

Run whatever you run it's your build. Today's single chains are usually sufficient for whatever setup. But if you have a double and want to run it, run it.

I'm not sure what you have to do when running that front sensor though. If the sensor hits you may need to back out and go to a single chain. Getting the sensor to the exact right clearance sounds like it could end up being a massive pain if you have to shim the sensor. Can work though. One way to do it is use a piece of cereal box card board and place it on the tip of the sensor then slide the sensor in the hole until it hits one of the raised areas on the crank gear that the sensor reads. See how much gap you have at that point and shim the sensor to that distance. There are some OE sensors that are adjusted that way and it works well.

 

The gear should come setup so the sensor is stock depth already so no shimming should be needed.

 

Yeah it's that should thing that gets ya sometimes

Being that the double roller pushes everything forward I didn't know if it would affect the sensor since it affects the oil pump and timing cover, it made sense it may affect the cam sensor depth. I've never shopped double rollers to see if they are gen 4 front cam sensor friendly so I threw it out there.

 

I approve of this post.

 

Lol...work smarter not harder.
