GM motor sport have the cam package on sale, for a cam in an L77 it going to cost $4100 that includes dod delete, not sure on how much extra the heads are to be done.

I will NOT be doing any boost in the seeable future.
Is it worth doing the heads to get a little extra power?

How much more fuel would a stealth cam use? Its a very small cam but worth knowing as ive heard people say don't get a cam due to the increase cost of fuel.

How much louder is the car with the cam? Currently have full 3inch with rex headers and cats and mild steel catback xforce.

Might make the drive to GM motor sport today and see it all for myself. 2hour drive from were I live.

Thanks,
PS. if you mention another make of car in this post, save yourself the hassle and get off the JUST COMMODORE forums.

From reading GM Motorsport's website a stealth cam for an L77 is as follows:

Stealth - Duration 223/235 @.050 - Lobe Sep 115 +Adv. - Valve Lift INT 0.610 - EXT 0.620


This is the specs for a stock cam for an L77:

Duration 196/208 @.050 - lobe separation 116 - lift 0.478/0.466

Good head work is not cheap.

The stock heads flow okay and any work on them for the package you're looking at would be a total waste of money.

Where about do you live to have to travel to Melton? There are plenty of good shops around.

with that cam u should get close to factory fuel usage just depends how good the dod was as sometimes its not worth using, cruising should be around the 7-9L/100 on the instant display, but anytime ur on the throttle u will use more as the engine will be ingesting more and make sure tuner keeps DFCO active

There doing the "special"

They delete the dod, don't think it's optional to keep it once they cam it.
Is the DCFO where they tune it and make it from low lumpy to high lumpy? Don't understand much about all this, but I'm under the impression it's the tune that makes it lumpy not so much the cam.

I'm sure 07GTS can give you far better info than me but it controls the fuel usage on deceleration.

Leaving it active will slightly reduce fuel usage and quieten the popping noise often referred to as overrun and as far as I know the parameters can be changed to control how much fuel is escaping on deceleration.

That's my basic knowledge from what I think I remember my tuner telling me when he asked if I wanted it or not.

Personally I like all the drama of the overrun but saving fuel has never been a priority for me.

The lobe separation has a lot to do with the lumpiness of the cam with a high number smoother than a low number and from what I understand a good tuner can control that to some extent as well.
