Deciding on cam, Torquer V2 or MS4?
And as for lifters would running GM LS7 lifters be satisfactory?
If anyone has cam recommendations besides these two please let me know!
Thanks
Looking to make good power but maintain street drivability.
I have a 6 speed manual ZO6
As for other mods, I have an air intake, Long tube headers, X pipe, axle back exhaust, LS7 lifters, were building a fresh LS2 block with brand new GM parts on the bottom end, valve springs are double springs.

Slightly out of my wheelhouse given the extra displacement, but it seems to me you might be able to go with a slightly bigger cam to take advantage of the extra cubes?
That said, I'm a fan of smaller cams to begin with. I think the Magic Stick series of cams is too big for what you're looking for. Perhaps also consider a BTR Stage 2 or a Cam Motion Titan 4 as well.

People love to say driveability is "all in the tune". Certainly there is a lot of truth that a well sorted tune will provide a stable idle and good throttle transitions. But keep in mind that there are trade-offs with longer duration cams. You will have less low rpm torque so you have to slip the clutch more. There will be surging at low speeds transitioning from light throttle to no throttle. You will have smelly exhaust (assuming no cat converters). Then there is the side effects of high valve lift. Be prepared to replace valve springs every 40k to 50k miles. Maybe not everyone drives their cam'd C5s like I have (391k miles and 6 cams).
After having upper 22x° duration and mid 23x° cams my current one is 222°/224°. I had to add a bunch of fuel below 4,000 rpm from my previous tune - indicating the inefficiency of the larger cams at lower RPM. This smaller cam is a better choice for daily driving, but doesn't have the lumpy idle that everyone wants.
Bottom line is choose what best suites you for driveability, power, and idle quality (sound). If you don't like it, change it again.

If it was easier to change cams, I'd probably try something like a 224/228 for more power under the curve and better street drivability (I've got a 227/234 now)

Most people don't mind and even like a tough sounding idle. They like the loping choppy sound. What many customers don't like is the bucking at low RPM. And some complain about the raw fuel smell that can be caused by camshafts with a lot of overlap.
I will give a few options and talk about their characteristics.
A popular mild off-the-shelf camshaft for the LS2:
http://www.cammotion.com/camshafts/m...218-224-116-3/
This camshaft will have a mild performance idle and improved power throughout the RPM range. We call this a "no-sacrifice" camshaft because it drives just as good or better than stock and picks up power throughout the entire RPM range. It is no dyno-hero camshaft for sure, but you can expect it to pick up about 20 HP over the factory camshaft.
The next level of mild cams is a sleeper cam I have been making for customers. It is a 224/230 duration @.050" lobe lift with 116 degree lobe separation and .621" lift. This camshaft will also have excellent drivability in an LS2 Vette, have a mild, but noticeable performance idle and pick up about 35-40 horsepower over the stock camshaft with a wide flat powerband.
Our most popular street performance camshaft is our Titan 4 camshaft:
http://www.cammotion.com/camshafts/t...227-232-113-4/
This one has a mild lope at idle, very good drivability and excellent power. While you will experieince some bucking in the lower RPMs, many customers feel this one is the perfect balance of performance and drivability for Vette owners who want to hear lope/chop at idle.
One of my favorite aggressive street cams is our Titan 5 camshaft:
http://www.cammotion.com/camshafts/t...232-238-113-4/
This one is borderline a street/strip camshaft. It makes excellent power, have a tough sounding idle and makes great power. It will buck more than the Titan 4 and I would say this one is more for the hard core stickshift Vette owner.
The most aggressive off-the-shelf cam we sell for the LS2 is our Titan King LS1 camshaft:
http://www.cammotion.com/camshafts/t...236-244-112-3/
This one is all business! Big loping, choppy idle, great mid-range to upper RPM power and no concessions given for drivability. So, expect bucking to be just part of the deal when you want to maximize power.





The Torquer v2 is about as big as I would go on a stock rear gear in a 6.0 and a touch larger than I would do in a 5.7 on stock gears.

So think about your entire build. What intake and headers are you going to run? If stock, you might want to select a smaller cam like a cam motion Titan 3 or something.








and have you done 3.73, 4.10s etc?
