Hey guys i have a 68 camaro. im told that it has a 72 chevelle 350 SBC i was wondering what would be the biggest cam that i can go with because im still running stock heads. i was looking a .504 Lunatti VooDoo cam but im deffinately open to suggestions. i want a cam that will give me a ruffer idle and will sound good with a full 3 in exhaust system- thanx guys

 

call jegs or summit racing. Usually if you get an higher lift cam you need lifters to go with them, new push rods, ect. Also buy a Cam installation kit.

 

bigger doesnt mean better. the bigger cam you go, the more you lose your bottom end power. getting a low end cam, duration around 210, you will have good bottem end torque, and will spin tire no problem. going with a cam upwards of 280 duration will give you good power up high, but it will hurt your bottom end and be annoying driving around roads. i would find a compromize between the two, more towards the bottom end. a camaro isnt exactly a lightweight car. if you want that rough idle, get a hydraulic cam with a duration around 240-250. hydraulic cams make a rougher idle then mechanicle, and 240 duration is plenty, and you will keep your bottom end too. when you get a hydraulic cam, you MUST also have hydraulic lifters. dont use the old lifters, always get them new when buying a new cam. you might also have to buy new rockers, pushrods and springs when replacing a stock cam and rockers to a new cam with a higher lift.

 

thanx guys i can use all the help i can get. also what is the most amount of lift that i can use on stock heads will .504 be to much or should i go lower

 

.504 was the lift by the way haha short mental glitch sorry

 

There are a couple of nice little cams from elgin that are cheap and will run fairly decent with your combo. I build engines for folks and it's up to you as far as how wild you go.

The first cam kit I would recommend is Part# E1029K, it has 214degrees@.050", .443" lift 112 lobe separation angle.
This will give you a mild lope and better midrange power. It will work well with the stock converter. It is one of the cams on this page:

The second one is slightly bigger and might require a better converter: Part# E1166K,
.453"lift intake/.480" lift on the exhaust, 216@.050 intake/ 228@.050 exhaust, 112 LSA.

The 3rd works very well with a 3000+ stall converter: Part # E1165A
Lift .488/510, duration @.050 234/244, 106 LSA. This one is not for the weak. You will experience a dramatic drop in fuel economy and idle vacuum. But, you will have explosive mid range torque and will keep pulling to over 6000rpm. You will need 1and 5/8" headers at least, and a 650+cfm carb and at least Weiand Stealth or performer RPM intake, but preferrably a Weiand Team G or Edelbrock Victor Jr.
Have fun!
