I'm building a chevy 350. I'm looking into a cam and lifter kit but not sure on the brand of a cam to get or what duraction to get. But I'm not looking into a stall converter. Thanks.
without more info , i would start here. http://www.summitracing.com/parts/sum-k00072/overview/make/chevrolet and this http://www.summitracing.com/parts/sum-g6600-9/overview/make/chevrolet need to know what transmission and gearing. what vehicle. tire size. etc.
any Hyd 280 to 286 will give fair vacum and not call for a higher stall convert. stayaway from the mother thumper cams due to no spring mods.
Contact a camshaft company, such as Comp Cams, and give them the details. You should be very specific, engine size, compression ratio, intake system, gear ratios, ect. Have all info available when you call and they can give you a recommended cam.
When you contact the Cam Company they will have a questionnaire to fill out and then their software will give them a list of cams. This is the CompCam software, I answered some questions the best I could, such as heads, intake, carb exhaust. You should know this before you contact a company. There are many good companies out there, or you could buy from Summit etc, the specs in the attachment will be a good starting point. Example;
im new at this im not sure witch lifter type to select and forced induction to select. And im not wainting to go with comp im wanting something diff.
There are as many opinions as there are Hambers. If you are a newbie to the game, you may do best to call the techline at Summit racing, or Jegs or a similar company, and talk to a customer service rep. For my .02 cents worth, I'd run the isky 262 supercam http://www.iskycams.com/pdfcatalog/2004-05/page62.pdf http://iskycams.com/cart/index.php?main_page=product_info&products_id=4848&cPath=77
Stay around 225 duration at 50 with a stock converter, lift in the 460-470 range, you can always go smaller than this. What's the car weigh, what gear? There's plenty of good cam companies, I prefer comp when building something nice, I've used plenty of off brand cams in stock/ mild street engines without issues. If you're using stock 194 heads "exhaust challenged" consider a dual pattern cam, this give you a different duration and lift on the exhaust to crutch the exhuast side
Forced induction would be a blower or turbo charger. Choose Either of those or no/none. Lifters are two basic styles - flat tappet and roller And two basic types - hydraulic and solid. Your everyday belly button before 1996 will have flat tappet hydraulic lifters. Early High performance SBC had flat tappet solid. After 96 they had hydraulic rollers. Your highlighted solid roller choice is a max effort, high dollar, high maintenance lifter.
I am by far no expert, but from an old man's street opinion, assuming you want to drive it, not make it a rough idle or high reving before max performance set up, talk to some folks that are realistic in their claims. I would stay away from the cams that don't really do much good until over ~4000 rpms, as well as the rough idling ones that really don't do anything off the line. And remember the cam is only one of several major parts to make your engine run like you desire... Find someone that has one similar and go look to it, as well as ride in/drive it if possible.. As I said..JMHO.. But I really do enjoy my little beefed up 283 that was built with that in mind every time I drive it.... Good luck..
Comp magnum 280 is one of my favorite cams. 230 @ .050 110 lobe separation. No go with a stock converter though unless you like two footing it at lights. Not sure why wouldnt want to change converters, an 11" 2200 or so stall would work fine and is not noticable on the street.
As others have said, most cam company's have very good customer service when it comes to selecting the proper cam. Give them a call tell them what you have and what you want to get out of it and they will help you out. If your having machine work done to you car the shop may have an engine builder who can help you out as well. Bottom line is there are plenty of life lines out there so do the research. One of the most common errors in engine building is selecting a cam that is out of sync with the rest of your build.
I'm trying to stay away from stall convert so what is the biggest cam I could go with Posted using the Full Custom H.A.M.B. App!
Do you want to make noise or maximize the combination? Some guys just want the choppy idle noise, otherwise no reason to get the biggest cam the converter willl take. Depends on what the rest of the engine specs are, car weight, rear gear, etc.

Not sure what you have against Comp, but the XE268, or XE274 are great all around cams. The 268 would be my personal choice, but I do not know how you plan to drive whatever it is you are building.
So if i go with one of thos cams I wouldnt need a stall and I'm building a 60 f100 Posted using the Full Custom H.A.M.B. App!
I ran the XE268 in an OT 68 Camaro, with a th350 and 3.08 gears. Stock stall and I drove the snot out of it. Could have used more gear in the rearend, but it was a daily driver so it needed a bit of mileage...lol
Well about 4mpg in the city...I was 20..lol I was also running a 650 double pumper (Like an idiot) On the highway about 14mpg.
