I've used comp camps in a couple of my engines and had zero issues. I think if someone got a hold of an older on the shelf comp cam and lifter set, things would be fine.
Are we talking about Dan?I'll add my own two cents to this.
Normal order of events:
1.) Buy project car, have big wide-eyed dreams of big hairy burnouts and jumping rivers just like the General Lee.
2.) Find a crusty 360 on marketplace and haul it down to the machine shop and tell them to build you the biggest, baddest stroker imaginable. Wait one year, seven months before retrieving a motor that went over budget by about four grand.
3.) Five years later, after finally paying off the home equity loan you took out to pay for the engine, you find out it isn't going to bolt in to your car... waddaya mean the slant six transmission won't fit a 360??
4.) Two more years of chasing parts, and you decide the car looks kinda ratty to put that nice engine into... off to the body shop.
5.) Two years and another home equity loan later, the body is back in your garage. You slide the motor out from the corner and put it in front of the car, and make vroom vroom noises. Over the course of the next year you put the engine in and out of the car 3 times getting everything to fit and finding those last bits you need...
6.) Ten years after the motor was built and every ounce of assembly lube has oozed out, the cam break-in lube has turned to feldspar, and a colony of field mice have set up housekeeping in your intake manifold; you fire it up- hmmm, that doesn't sound good. Uh-oh, the oil pan is full of babbit and metal shavings. Out the engine comes, and tear it down- eeww, the cam is flat and the metal must have taken out the bearings... my cousin said all new lifters are bad so that must have been it.
7.) Get pissed off and sell the whole mess on marketplace for about .05 on the dollar and go online and tell everybody how crappy XYZ's cams are.
Moral of the story: Get the rest of the car in shape and build the engine last, not first.
Rant over.
To the OP's question- most all of the major manufacturers have quality offerings; yes, I keep hearing this and that about Comp Cams, but have not personally run one of theirs in a looong time so I don't know. Isky, Howards, Racer Brown, Lunati and Bullet (among others) all have solid reputations around here, so pick your grind and break it in correctly and you should be fine.
haw!Are we talking about Dan?
Go Roller no break-in required and you don't need to run special oil. I have a hydraulic roller in my 440 and it runs perfect, and I run 10W30 oil, you don't need any special additives. I got mine from Scott Brown @ Competition Components, great guy and he will steer you the right way to go.my next hobby stock car 360 engine flat tappet hyd cam. with all the hyd cam breakin failures is there a brand that will give me slightly better odds of a sucessfull breakin? (along with all the proper preperations of course). I've heard good regarding Howards. & should I have it nitrided? thank you for your time. RR
undecided on a cam. someone (on here) had priorly suggested 718041-09. RPM range 2300-6000. intake dur at .050 235. ex duration at .050 243. advertized intake duration 289. advertized exhaust duration 297. intake lift .488". exhaust lift .480" lobe seperation 109. it is a 63 dart stock car on a 1/3 mile high banked dirt track. 360/904/5:57 8&3/4. I ain't a cam guy so these are just numbers to me. EDIT that cams' specs say "circle track height rule only", not sure what that means. also a 7K rev limiter is required (tho I dont wanna get anywhere near that) and I almost forgot, the required CR is 9-1 max and will be running EQ heads with the 1.6 ratioalso, tell me you're gonna run this cam: DODGE Howards Cams 712901-12 Howards Cams Hydraulic Flat Tappet Camshafts | Summit Racing
No. That wouldn't include a car at all. Real short conversation.Are we talking about Dan?
i was somewhat joking about using the cam that i recommended.undecided on a cam. someone (on here) had priorly suggested 718041-09.

Good comprehensive advice/info! & very much appreciated. JYH I will take your advice & note that info when the season starts next April. I do have the 718041-09 cam & someone had priorly suggested another one but Summit would not let me exchange it even with it still unopened (said it had been too long since purchase). yes 2bbl carb & no max lift limit. should I have the cam nitrided?given that you have to work within the parameters of the rule book, you'll want to do two things. first figure out what kind of speeds you'll be running, or need to run. then tailor your gearing/tires and chassis to that. with that locked in, then you can sort out the engine on how and where you want to make the power.
i understand that you're hemmed in by the rules: 9:1 comp, 2bbl carb (i'm guessing), and likely you're limited to a max lift.
provide as much information as you can and we can likely put our collective heads together and get something that's at least close to decent!
