Any body run one? Or did you run one and now run something else? How did it work out? And what kind of comb do you have? 
Herb McCandless special, he claims to have told a buddy at Comp he wanted the biggest .904" tappet solid possible and that was the result. I have a friend who runs one in a 451" RB (.055" over 440) with flat-top pistons and home polished heads (not hogged) with 2.14x1.81" valves and an M1 intake who runs high 6.50s-6.60 flat in the 1/8mi in a 2700lb Duster. (4.56 gears, transbrake 727, 5000stall 8" converter, 29" slicks) Sounds bad-A$$ (290@.050"!!!) and zero maintenance with Isky iron rockers and a 950hp carb... RB

My favorite cam! I had one in the 451 in my Horizon. 452 heads, flat tops, Six Pack rods, steel crank, M-1, and a 1050 Dominator. It was like a time slip copying machine! One night, 2nd, 3rd, and 4th round; the car went 9.769 on each of those passes.

a great cam sure....BUT you are talking late 1980 early 1990's technology.....SURELY in 20 years there are better cams availible..
IF you have on euse it, but if you are buying a new cam....call a reputable cam company and get something new
ALSO dont forget, A lot of people were using these with the Team G intakes and Factory 452 or 904 heads. THere are way better heads out there now, even Edelbrocks etc that would work better with a newer profile camshaft

That cam has a ton of duration. I've never used anything that large before in any of my dyno testing. Guess maybe I should try it some day just to see how it stacks up.
My 514 engine makes about 850 hp with a cam that is only 266 at 050. So I'm not sure why I would need 24 more degrees of duration?
440Jim is running the Comp MM 305 which is 279 at 50 on the intake side with .650 lift. So the 324/.650 has the same lift but another 11 degrees of duration at 050. I'm not sure that adding that much duration to a car like Jim's would make him quicker. In fact, it might make the bottom end soggy and slow him down?
I think the reason that cam is so big is because it was designed to work with ported 452 heads that didn't really flow all that well. At least that is what I was always told. Like I said, I've never put it on the dyno to see how it compares to a more aggressive cam like the MM 305.

The comp cam I have is solid lifter .650, valve lift at 1.5 , 108 lobe center line. .435 lobe lift , cam is at 324 at 15 degrees and 290 at 50 degrees , RPM range is 5000-7200 and it doesn't smooth out till 6000. You better have a steep converter. 
it's ok to butt heads, just don't do it with a butthead

With todays heads, that much duration is not needed and to much, IMO. I too feel it was intended for the poorer flowing steel factory heads. mike

Can we hear more about this combo and camshaft?
There is probably a thread or two on here that covers my 514 engine. The cam in it is 266/272 but it is a roller cam so it isn't really apples to apples. 440Jim's engine is probably a better comparison. He is going really fast with a big flat tappet cam.

Low end with this cam is really pretty good for such duration numbers, I've had 1.25 60's with a 8.20 SLR on a carb. Of course the 60 numbers are very dependant on chassis and convertor which must fit the cam/engine combination. It is a good cam, off the shelf, it can get you there without all the crap, if you are wanting to tweak out the most, you wouldn't be talkin' a flat tappet anyway, its a very good and fast bracket cam without question, but as always its the combination and all components are important.

My thought, too.
Also, I was expecting 440Jim to pop in on this thread. IIRC, he did try the COMP .650 and it wasn't as fast as some other cam(s) he tested it against.

Hope no one minds bumping this older conversation.
If two cams have duration 324 and 305, and both lift 0.65, the second one seems more practical. If we don't plan to rev high, or put high mileage on the vehicle, some of us want to stay with solid tappets, ruling out solid rollers. But those rollers could help in low rpm torque. I suppose they can ramp up faster. An example is 23-706-9 --- duration is only 263.
But for solid tappets, has anyone tried and preferred the MM305 cam with an add'l 4-6 deg advance? Even if the rpm range came down only 10%, that would still be appreciated. I think the MM305 p/n 23-630-5 sweet spot is 5000-7500. For most of us, that's a bit high.
