I have a pretty much stock 350 in my 67 Camaro and I am wanting to put a nice lopey sounding cam in it until I can have my new motor built. The car will have a M20 4 speed and 3.73s. The car currently has an edelbrock performer intake, 600 single line holley, HEI, headers, and a dual exhaust with 40 series flowmaster mufflers. I have an XE274 cam sitting in the parts pile for my new motor, but I was leaning towards one of Lunati's voodoo cams for my stock motor. Would their 268 grind be too much? I don't think I'll spin the motor over 5200, but I don't want a wimpy sounding cam in it either. I know something with a narrow lsa will give me a nice sound, but I don't know what all is out there. I have basically been researching for my new motor, but haven't given much thought to my current motor. Any help is greatly appreciated. Post up sound clips of your cams if you have any. I would like to hear some of the cams that are on the market today.

Remember that you may have to replace the valve springs if you get too wild with the lift numbers.

You are right, a smaller LSA will sound nice, but you may give up some power and vacuum too-


One of the things I try to do is to put a little more compression in a motor and put in a cam that is just a tad oversize so it sounds good and bleeds off a little cylinder pressure to avoid detonation.

If your motor is an old stock, L-48, about 10 to 10.25 to 1 CR. motor it will be fine!

If it is a newer 8.5 to 9 to 1 CR. 350 motor, NO!

As always, jmho..

this cam gets used alot in cars similar to what your talking about, it produces both good mid rpm and upper rpm power and a very noticable lope at idle, and it works with the stock valve train clearances ,without being so radical that street drivings a P.I.T.A., you might want to give crower a call and see what thier thoughts are on the combo

CROWER 619-661-6477

I am in the same boat , and going to go along with this threadsince I have almost the exact set up. YES i did read the 200 threads on cams here. Hopefully I geto the same result. I have a 327 with 60cc heads 2.02, 1.60. stock deck and .039 gasket. full headers, 4spd...I was stuck between the lunati 102, and lunati 103. I want street torque and also will not be screaming the motor over 5500.

The crower seems right between the 102, and 103 and may be the way to go. What is the right one to have a non stock cam sound, without my wife thinking " man this thing runs terrible" when we are at idle. YES , I did have a 290+ duration cam in my chevelle in highschool that sounded like a washingmachine with a load of towels out of balance.

I alaos understand we needto the get the DCR down, if we both have 10.5:1 or higher static comp. With this in mid I saw beig stick withthe 103.

Thanks for the replies. The motor I have now is a lower compression 350, probably 8.5:1 with 76cc heads. I have a set of vortec heads that I could use on this motor. They are the 64 CC castings. This should bring up my compression by one full point, to 9.5:1 right? Then I would be able to use a larger cam, such as the XE274 that I already have. I could use the gm valve spring kit #12495494 (http://www.sdpc2000.com/catalog/3533/products/2005/LT4-SB-Chevrolet-Valve-Spring-Kit.htm) without having to cut the spring seats, right? They are a single coil design good for .525 lift.

I really should just hold my breath and styay away from these...
I'll try harder next time.
THE CAMSHAFT IS THE HEART AND SOUL OF YOUR ENGINE. HOW IT SOUNDS AT IDLE IS NOT A DESIGN PARAMETER!!!

The MAIN reason I am getting this cam JimM is for the sound, because this motor is a stock 350 and I am not going to push it to the max. This motor will be in there only until my new motor goes in. It will probably have 3,000 more miles put on it before it comes out. That is why I am not concered about peak peformance with this engine, because that is not what it was designed for.

I agree with Jim here, if you aren't putting a cam in for performance, then imo, you are wasting your time. If you just want it to sound nice, put some headers on it, 2.5" true dual exaust and drop it out a set of 40 or 50 series flowmasters. That should I think sufficiently upgrade the sound of your vehicle for you.

Ozz1967 That's what the car has on it right now.

I want a little lope to the sound until my high performance 350 goes it it. The motor I am looking at building should be around 475 hp. So I have peformance in mind with that motor. There is no reason for me to force this motor when I don't have to. I just want a nice sounding idle and something that would work a little better with the 4 speed I am going to put in it. A cam kit is only around 300 bucks and I am willing to spend that for the type of sound that I want.

sounds like an xe268 for you then or something similar.
unless you want to go to screw in studs and milled valve guide bosses,you will need new springs anyway.did you plan on removing the heads?

the 268 "might" run on stock valve springs,but you have to check for coil bind,and keep a sharp ear out for valve float.for gods sake,remove the oil drippers!(little upside down cups on top of the valve springs)!they cost me a set of valves cause i was in a hurry and forgot to remove them.
another good possibility is the good old cc280h.you would need the same cautions as above.sooner or later you will have to replace those stock springs though.they are awesome for cam break in though!

I'm not the expert here by any stretch of the imagination, but I can tell you what I just did to my motor to really wake it up.

I read most of the posts here regarding cam choice, compression, heads, intake, exhaust & carb combo choices. I received some great advice from many members here (especially Eric68). I finally decided on my new parts to get a nice lopey idle and add somewhere around 100 horsepower to my motor. I chose 64cc Edelbrock RPM heads & the Lunati 268 cam & added and Edelbrock Performer RPM manifold. I'm now at about 9:5 to 9:75 compression and the thing sounds great at idle. I've only been able to drive it once & it was amazing how much more power it was making (have not even re-tuned the carb yet). I labored about going with Comp Cams XE274 vs. Lunati 268 and in the end just decided on the Lunati based on some reviews. Both are reviewed very well.

I would have to agree with most of the other replies. A tough sounding idle is good, but if the car runs like crap, it's just not worth it. Pick your parts as wise as you can.

Just my .02 cents.

Thanks for the replies.

I couldnt disagree more...I dont like calling cam companies for any kind of recommendation. Ive called about every major cam company out there 3 times with the same exact info and i allways get different answers. The only ones who shot me straight all 3 times were Ultra Dyne, Cam Motion and Bullet. THe bast thing to do is gather a TON of information read up, ask questions and educate yourself. Take advice but then make your own call

Crane's 274H06 will give you a nice "cackle" like I think you want as well as should work fine at 9.5 to or so CR, imho..

The 106 LCA is what will give the "cackle", plus, being 274 will still work pretty darn good at 9.5/9.75 or so CR.

NOTHING FANCY here at all and it should be a dandy mild street motor!

Thanks for the heads up on the cam companies novaguy73. PDQ67, thanks for your input as well. I'll definately put some research into that cam. I was thinking about buying a cam with a tighter LSA than my current one (110).

please don't forget to check your clearances!

Novaguy73 I understand what you are saying about getting quite a few different recommendations from the same company. Just like this board though different people have different views on what they are told or read. This will also happen if you go to different machine shops each machinist has their views on what is the correct way to build engines. That doesn't mean they are wrong if they are Professionals and put out a great product there can be more than one answer. The way to resolve this is through THe bast thing to do is gather a TON of information read up, ask questions and educate yourself. When you build engines and deal with these companies you will find a guy that understands what you are looking for better than others and thats the guy you need to ask for when you want a cam from that company. There are so many possible grinds there could be 20 that would give the same basic results for any one application. If you have found the brand cam you like and have a good working relationship with a particular fella there on getting you the cam choices you need then thats who you need to call and get him to recommend the cam and do not look back. You need to be able to totally trust this guy just like you machinist. Otherwise you are not going to have a very pleasant time while building the engine and you will always wonder no matter how well it runs if you left some on the table if you were not totally confident if the choices you made on who to use. Ultimately 67SS&99SS it is your choice but I do recommend talking to the company and getting their recommendation especially for engines not of the normal factory configuration.

Ok there is my 5 cents on it. :)
