I have a question for those who are more mechanically inclined the I am, which wouldn’t take much. I’m getting a cam with the specs of
232-248-630 lift. How big or small is this cam barely audible, mild, or kick ***? Would this cam work if I decided to get my 2013 vette supercharged at a later date. I like to hear the cam sound but I didn’t want a cam so big the car would be hard to drive. Some opinions foe you mechanics and tuners would be helpful.

 

I could use some help here, should I put it in another section?

 

That is a pretty healthy cam and not something I would say is "small"

What is your total setup? Remember the cam has to work with the rest of the car.....so in some cases what might be HUGE on a stock setup, might not be to bad on a car with heads, intake, headers, exhaust......

Also if you are working on a auto car, the cam and torque converter have to work hand in hand, and that is not something that is going to work with a stock stall.

 

Doug Rippie motors is installing the cam, AR headers, Calloway intake, ported throttle body and intake, catch can, new plugs, and other accessory parts as needed. He said the drivability would be good with that cam and figured around 630 HP at the crank, stock is 505HP, with the LS7. I’m not enough of a gear head to know that is why I was asking on the forum, but I’m not getting much response. 6 speed tranny, 8,020 miles 2013 427

 

Biggest key thing you said there......427. First thought was that cam was going in a LS2/3 engine and that would be a big cam. for the LS7, not to bad at all.

Don't know if I would supercharge the LS7 at that point....at least I wouldn't do so until you weigh out the risks involved with doing so on the LS7 as they are not as robust as the LS2/3 setups on a stock short block.....depending on the type of supercharger and amount of boost.

 

well I’m sure you know what your talking about. What do you mean the LS7 is not as robust as an LS2/3. LS7’s aren’t as solid as the other two and can’t take the added HP as well?

 

LS3's are engineered for boost - hence the ZR1 uses the same LS3 motor which is rebranded to LS9 after the blower install. LS7's work better naturally aspirated.

IMHO! I would install the most radical cam available for your car. I installed a very similar cam in my GS and I'm somewhat dismayed by it. Go big or go home!

 

Actually the LS9 is more different than that. They use a completely different material Alum. for the block and cylinder head castings. The head bolts are larger than that of the LS3, and they use a different head gasket. Not to mention the piston oiler's, forged crank and the fact it is only a 9:1 compression engine.




Couple things plague the LS7 for boost. One it has a high static compression from the get go, so that is going to limit boost or force you into race gas/E85/Meth injection setup to help with timing and reduction of detonation. The cylinder liners are a bit thinner than that of the LS2/3/9 cars so if you do have a bad knock...good chance it can do block damage. The factory pistons are not what I would call robust either and have seen a number over the years have pieces of the top ring land break away.

This isn't to say you can't supercharge the LS7, plenty have done it, you just need to pick the components and find what your limit is....for most it is the fuel the car is going to run.

 

........I call BS on that one. I haven't read that anywhere.

BTW! I'm still waiting on you to honor your business model and replace the faulty x-pipe you sent me. Any idea when that will happen?

"The cylinder block is very similar to that of the LS3 or L92, constructed of cast aluminum iron sleeves. It also has the same 4.06” bore diameter but it achieves it in a much different way. Race engine builders for many years have torque plate honed their engine blocks, just like the new LS9. The process simulates the bore distortion caused by bolting down heads. Then the block is honed, theoretically making the bores perfectly round when the heads are final assembled, keeping the bores as round as possible offers the maximum sealing.



Another new feature of the block appears to be a switch to alignment dowels rather than registering on the outside edges of the main caps like the majority of the LS line up. The cool part is that the new main caps are made of solid steel, a big power upgrade the aftermarket has been doing for years.



The cylinder heads are very similar to the LS3’s but are constructed using a sophisticated rotocast process and 356T6 aluminum alloy. The result is a stronger, tougher head, with better heat control properties. The port designs are essentially the same, as the LS3, but they have unique cast in swings which induce a swirl in the intake air. The large 2.16” intake valves are made of light weight titanium material, the exhaust valves are sodium filled 1.59” a good combination of durability and minimal. In another weight saving effort, the LS7’s titanium keepers are used."

 

speedforhire--OK time out, no fair jumping on someone trying to help me out.



motorsports-- so the cam, headers, CAI is probably my best bet for mods and then leave well enough alone right. Sounds good to me, thanks for the advice

 

Hello, What is the LSA? I have a C5 with a crate LS3 N/A with H/C, Kooks 1 7/8, cat back, etc. I'm running a 237 / 249 114LSA .624 lift and I can tell you that it is fairly healthy cam-not the biggest but also not the quietest, street manners are good for me. This is all going to depend on the tune. I drove one of my friends cars with a much smaller cam and it was bucking and surging all over the place compared to mine. If you have a tuner who knows what they are doing you can get the biggest cam to drive and feel fairly close to stock if that's your taste. Lastly, it does have some lope which I don't mind but also with overlap you do get some fuel smell so its a trade-off.

Here is a quick clip to let you hear it (video is crap, sound is ok)

Excellent point too...

 

I think Doug Rippie (DRM) OUT OF MINNESOTA IS A PRETTY GOOD TUNER. VETTES ARE SHIPPED FROM ALL OVER THE COUNTRY FOR HIM TO WORK ON. I GUESS I WILL FIND OUT WHEN ITS ALL DONE. HE SUGGESTED THE CAM AND ALSO SAID IT WOULD NOT BE A GOOD CAM IF I SUPERCHARGED MY CAR. IF HE CAN GET 630HP FROM THIS BUILD WITHOUT A SC ITS GOOD ENOUGH FOR ME. I CAN GET IN TO PLENTY OF TROUBLE WITH THAT KIND OF HORSEPOWER. LGMOTORSPORTS I DO APPRECIATE ALL YOUR HELP. IF YOU WERE CLOSER WE MAY HAVE BEEN ABLE TO DO SOME BUSINESS.
