Hello, Anyone have cam specs, advertised lift, duration etc? I hear it crosses to a Crane number, as they were ***ociated with or purchased by Crane. I am hoping someone has an old Cam Dynamics catalog sitting around. Part number is 10017 I appreciate the help, throwing together a budget street motor and have this cam which is new. Thanks, Tim Feel free to email me directly with the info. sfaboston@hotmail.com www.sfaboston.com
This is a hydraulic lifter camshaft. Advertised duration is 274 degrees on both intake and exhaust. The duration at .050" cam lift is 218 degrees. Cam lobe lift is .300", resulting in .450" gross valve lift with the standard 1.5:1 ratio rocker arms. Lobe separation is 106 degrees. Cam timing at .050" is: intake opens 7 degrees BTDC, intake closes 31 degrees ABDC, exhaust opens 39 degrees BBDC, exhaust closes 1 degree BTDC. The basic power range is 1800-5400 RPM. Depending on displacement and compression ratio, this will have a fairly rough idle. I'll email you a spec card copy. Regards, Chase
i need to know the lobe seperation on a cam dynamics sbc part # 10018 grind # 312 06 HTQ any help would be great Thanks!!
Happened to be fishing around and found this old discussion that had no resolution. I've been using the CD 100018 for over 17 years in my Camaro's 350. The specs are, in normal terms, .465 valve lift (with 1.5 rockers), 312 duration (at .004, the old standard, I believe), 230 duration at .050, 106 lobe separation, straight-up timing. It is a fabulous cam, not prone to wear with the shallow ramps. Horrible cold idle, good warm at around 1000rpm. You just need to tame it for the street. I did that the following way: 1. use fast-bleedoff lifters, Crane "Hi-Intensity" (what I use) if they're still available; I suppose Rhoads lifters would be about the same, this kills some lift and duration at low rpm, 2. time the heck out of it, at least 36 degrees, up to 40 if you can without pinging on your setup, 3. 3000-stall converter (if automatic), mine's a B&M, 4. at least 3.42 on the back (***uming stock-size tires); I use 3.73 with 28" rear tires (stock 26.1"), 5. with a Holley, change the power valve to 4.5 since you'll have around 13" of vacuum at a 1000rpm idle, 6. use a single-plane since there's no point to a dual, 7. run a good ignition (I still use the old ****og MSD6A). I got this cam back in '97 when it still appeared in the Summit catalog in a small box in the bottom corner as one of two Crane 'super 3/4' hydraulics with the blurb "fantastic horsepower". I opted for the hairier of the two. When my box came it read "Cam Dynamics". I figured they knew what they were sending me. Did they ever! Great cam once you figure it out, which took me years BTW.
Probably the old 274 H06 hy-cam. It will cackle some at idle and as you rpm, it will smooth right out.. A good old cam by me. pdq67
