installing hot cam

[logan1080]

so the best route to change the cam would be to pull off the front end?

I would suspect you could remove the serpentine setup and pull the radiator. After that its all about thinking happy thoughts and holding your tounge just right.

while that is a great idea... and ive done about 7 LS camswaps. on the 7th one, we had a lifter back out and drop. granted we got it out with a magnet, but if you are going to do it that way, shut off the stereo, pray you dont have an earthquake or that someone doesnt bump the motor too hard.

if it were me, id just pull the lifters.

the front end of the motor. along with the radiator and probably the condenser.

cam swap on an LS1 4th gen

If it's GMPP, is it covered on warranty if the dealer installs it? Any effect to engine warranty?

No need to change lifters, rod, etc. Just tune afterwards?

Does it effect MPG?

considering the lifters/rods/etc will be brand new, you shouldnt need to worry about changing them.

and a hot cam should work with the stock valvespring max lift. now if you go with a bigger cam, you will need to make sure your valvesprings are up to the job.

How hard do you think it'll be to get the dealership to give it the ls376/480 flash when they're done? I'm assuming the new cam needs a different tune, and the official program should not violate any warranty you're trying to keep by having the dealership swap them.

Remember, an engine is a big air pump, so more air in+more air out=more power!

Anyone know the part number and a link to where I can see this Cam?

IT's on the GM Performance Parts website. Here is a link.

You will also need a 3 bolt 4X Cam gear. The LS3 cam gear is now a single bolt design. A LS2 non GTO gear would work. The chain and tensioner are good to go.

This modification would not be covered under warranty. Also GM does not have a calibration that would work in the Camaro. As you know GM Performance Parts has a controller that is available for their crate LS376/480. That controller is not compatable with the Camaro.

I am sure that most tuners would be able to tune that cam change.

Yes, it's the same one for the LS1, LS2, LS6, etc.

LS3 heads take a completely different cam profile than LS1/2/6 based stuff. the heads are quite different. Huge runners and a lot of flow

I know it will fit and function, it just takes a different grind.

Hello Robin,

Thanks for the info! Now, when you say that the modification will not be covered under warranty, what exactly do you mean? Does the cam swap void the warranty or are you saying that the work performed to do the cam swap is not covered by the warranty (aka the labor costs to install the hot cam aren't free). Thanks in advance for the clarification!

Robin,

Thanks for the info on the Cam. I'm very unknowledgeable here...if I wanted this Cam, what is the part number and link for the 3 bolt 4X Cam gear? How much Horsepower would this mod add to the Camaro? Would I notice a lope? Would the car still idle fine?

Thanks again.

GM Performance Parts installs the Hot Cam in their LS376/480 Crate engine. It makes 480 Horsepower. No need for a different grind.
Most aftermarket cams have a lot more lift. You need to be careful with aggressive lobes and Piston to Valve issues.
There are cams that will make more power, but the Hot Cam has been around for a long time and works well.
