My friend needs help to choose a good cam size for his friends sbc 383 stroker. He wants more HP with a nice mean sound. He was looking at getting this cam... http://www.compperformancegroupstores.com/store/merchant.mvc?Screen=PROD&Store_Code=CC&Product_Code=12-212-2&Category_Code=12-CAM.... The 383 has a victor jr intake, its .60 over...so far thats all i know about it. No forged parts in it. If you need more info. please ask and i would give you the information as soon as i talk to my friend. Thanks

My friend has the 292 in his 377CID motor. He won't rev the motor past 5000 but it sounds very mean at idle.

That would be a decient cam, i would step up alitle it it were me,what you have to remember is that a cam that sounds mean as hell in a 350 isnt gana sound as mean in a 383 due to cid differance, im building a 383 right now im using lunati voodoo cam .505 intake .525 exhaust, 233/241 at .05 110 lsa it should sound decient but still be streatable

I'm building a 383 stroker with vortec heads clearanced for high lift springs, rpm air gap intake, cast crank, forged rods & hyper pistons. Will be between 9.7 and 10 to 1 compression. I'm going to use a comp XE284H (240/246 .507/.510 110lsa), which was recommended to me by comp's cam help techs. Should be a torque monster with nice hp as well.....and it'll sound sick idling :devil:

Use a DCR calculator to figure your cam. Chosing a cam just by the .50 specs is a piecemeal approach. PianoProdigy's calculator is very good at giving an idea on what the cam will idle like, compare DCR's of different grinds. Search in the LS1 forum and you should find it very easily. Good DCR = Easy power and more of it!
As to your current choice I would go a tad bigger. I ran a 224/224 .465 114/109 in my previous 360ci boat engine and it was a baby at idle. Nice short chop but nothing major with -4 degrees overlap. With a car you could go quite a bit larger. Lunati's Voodoo line are some damn nice grinds for HFT cams. They chose valve events that close the intake quicker than most out there and that's the reason they drive so nice and make power.
