Comp Cam Magnum solid 282S
I'm choosing a new cam with solid lifters and I'm wondering if anyone is using this cam and what results are you having...Thanks

Thanks for that info Motothead, What was your engine combo with that cam. I'm planning on running AFR heads 68cc......

I had a 355ci with flat top pistons about 10:1 CR with Sportsman II heads, 64 cc combustion chamber with 200cc runners, Air Gap or Vic Jr. intake, Holley 750 DP, 1 5/8" headers and 2.5 in. dual exhaust

The old 282S cam is a good baseline deal..but if you will spend some time looking through some catalogs..like the full COMP one or Crower etc...you will find that there are some killer flat tappets used in the lower level roundy rounder motors that make incredible street cams for hot rods. You can find very aggressive lobes with good stability, loing life etc.
I really like the Crower #350 cam...it's sweet. It looks a little wild on paper with a 107 LSA, but the small short quick lobes don't create lots of overlap. It idles very smooth with a nice lope and will scream to 7000+ rpm anytime you want. We currently have them running in a 327 with SR Torker heads and a 383 with ported 461 heads. We're using 1.6 rockers to put lift in the .530 range..works great.
There are others too...take a trip out of the ordinary stuff...plus it's just as easy to custom design one..doesn't cost anymore if you pick separate lobes. You can use intake lobes on both sides to create a pretty sweet one too..more aggressive lobes usually on intake side. There are incredible possibilities.

I'd be lying to you if I told you. It's a pretty weird deal. never been dyno'd.
It's a flat top with one valve relief piston, decked to .002 ABOVE the deck. It was originally designed for the car the 327 is in, but the other fellow wanted it. So we opened chambers in the 461's to get compression down to an honest 10.2 instead of the 11.0+ we were shooting for originally. The new owner wanted less compression. The heads are pocket ported with 2.02/1.60 valves. The tricky part is it's set up as a 283/270 appearing engine and is installed in an original 283/270 C-1. So that means it has the low rise 2x4 setup and cast iron manifolds. It makes incredible low end, but is airflow starved at top end I'm sure. We have another 2x4 intake that we are going to open up a good bit as well as work on manifolds. It will be at the Forum Cruise in in May and will be on the chassis dyno there so we can see how it does.
The little 327 runs deep 12's with a Doug Nash 5 speed, 93 octane and 3.36 gears on plain 'ole BFG street tires. Plus we've never done much tuning to it...there's a LOT more left in it.
It may not be perfect cam for your car....but I'm just saying I would shop around some..you can do much better.

I run a Magnum 294S cam. My engine has 10.67:1 CR. Brodix -8 Pro heads w/2.055 intakes, Ported and milled(for hood clearance) Victor Jr intake, needle rockers (1.6 ratio intake, 1.5 ratio exhause), 2.5" chevy ram manifolds, 6" 4340 AQ rods, factory side pipes modified for 2.5" pipes, MSD 6AL redlmited at 7000, a 750 Holley DP w/milled off choke horn, and a stock LT-1 air cleaner.
The 294S is VERY streetable and pulls well between 1500 and 7000 rpm. It idles at 900 rpm, and hits hard at 3500 rpm. The manifold is key to the combo, when using a Torker 2 the engine checked at only 248 HP
It G-techs 320 RWHP. For reference a stock '69 350/300 tests at 165 HP, a '93 350-300 Net HP checks at 193 HP, and my new '04 Viper SRT-10 tests at 414 HP.

I luv reading from yo u guys who have installed and run these cams vs the CHP referenced replies, I have a 383 stroker with Dart IE heads race ported by MountainMotor with 1.6's, speed pro flat tops, @10.5:1 compr. and will swap out my Torker (port matched) for a new Weiand Team G intake. I have always loved the 282s and 294s cams and had not talked with anyone running that Crower. I have a Holley 4779 with choke tower removed by MM for the strip and an Edel 750 mech dp for everyday cruising - now work done to it just slapped on out of the box - will need to change jetting to get best perf. out of that Edel, also have the original M22 with 3.55 gears. With the crappy 245/15" T/A's I ran 12.46 @ 116.2 with a fairly mild cam (crane 278) only ran at the track 3 times though so I am sure that with proper rubber I could of gotten into the high 11's - as what MM designed that engine to do. This is a 72 Lt-1/ZR-1 vert. with some racing history albeit unconfirmed by pics so I take that all with a grain of salt! I need to take a look at the valve seals as I am getting some blow by, the block has been decked. It's a great setup but I am so used to that power I want to now take advantage of those heads.

That's my problem, getting the most cam with good duration (at least 236) using a THD400 trans with TCI convertor that's 1,000 over stock, so 2,000-2,200 stall i'm working with. I'm ok with the 3:55 gears..I like the 294S cam Gordon ran but it's just alittle too much cam for this application with an auto trans...so the hunt for the cam continues.....
