You just QUOTED IT.

To whoever, send me one and I'll have it Dr'ed....


PM if interested.

Good Deal!! But I'll take the shootout as
an interesting conversation piece. I believe Bob's tuning skills ARE top notch and that's why HE gets good power from those Magnum-optioned motors (big block) along with his cam grinds.

so let me see if i understand this correctly, you buy a cam from "mr six pack" and you don't get a cam card? so you have no idea the lift, duration, centerline? when somebody asks you you just shrug your shoulders? or you try and have a converter built and these are some of the questions a reputable builder would ask you, what then?

---

That's why you go back to Bob K. He already "knows" what the profile will do for your engine, PROVIDED that your engine specs ARE what you say they ARE.

I wanted a stock appearing 440 magnum style engine with stockish intake and exhaust manifolds without having to sacrifice decent performance. I played the aftermarket cam crap shoot game and decided on Bob's cam after talking to him on the phone, factoring in his known engine build/car build specs, and his E.T.s.

According to published numbers provided by Pure Stock Muscle Car Drag Race , the race weight of Bob's A12 Super Bee is 3755lbs, in which they factor 441 Rear Wheel Horsepower given his E.T.s

Bob’s best E.T. to date was 12.09 seconds in the quarter @ 114 mph.

Bob’s known engine/car build on race day:

* 440 bored .060 over (453ci.)

* Venolia NHRA approved stock replacement pistons

* Mr. SixPack Camshaft

* Six Pack induction (975cfm actual)

* HP exhaust manifolds

* Factory dual point distributor

* Stock 906 heads with stock valve sizes (no porting allowed)

* Stock stamped steel HD rocker arms

* Milled heads - deck height of .027 gives him exactly 11:1 compression.

* Carter mechanical pump (M6903)

* Stock 12" Torque converter

* 4.10:1 Dana 60

* Duel exhaust with H-pipe and Dynomax Ultra Flo mufflers

* Reproduction bias-ply red line tires on stock 15-inch wheels.

So for me, the proof is in the pudding and I don't mind not knowing actual cam specs, only that it seems to work really well. I also know that after the sale Bob will help me dial everything in over the phone and e-mail because that's the type of guy he is.

Well said!!

i still don't understand the secrecy.

i could see if he was running a "heads up" effort and wanted to keep his personal cam specs a secret from his competition but, if he's in the business of selling cams on the open market, why the smoke and mirrors?

as previously stated, a cam doctor will pour out the specs in a matter of minutes so.......



i mean no disrespect to mr. six pack as i'm sure he's a nice guy, i just don't see what strategic advantage is enjoyed by the secrecy.

---

Maybe it is a thing called loyalty and respect for one man's hard work.
If he wanted to mass market it for a profit he would.

In this age of instant gratification it is'nt a stretch to see people upset by what they can't have.

Purchase his product and benefit from his expertise or don't and

Other words like principles, ethics, and values come to mind as well but whatever… different strokes for different folks I guess…

I mean common, if it’s the man’s wish to not openly disseminate his hard work and knowledge all over the internet and the like, than why not leave it at that? And especially if you have no interest or plans in running his cam anyway?

This topic has been gone over a few times over the years.........You guys are making this way too complicated........

The FACT is, there is ABSOLUTELY NO REASON to run one of his cams unless you're going to race your car in the Pure Stock races AND want to be certified..........Otherwise, call someone like Dwayne Porter and have one ground.........It WILL run better AND you'll even get the cam card.........

---

that's pretty much my conclusion...his camshaft design is optimized for the rules of the class he races in, and compromises were made to fit those rules. if you aren't bound by those rules, there are probably better cams out there for you.

Camshaft: The camshaft must be correct for the year, model, and horsepower claimed for the type of lifter (hydraulic or solid). Roller cams NOT allowed. Duration at .050" lobe lift must be within 1% of factory specs. Lift at the valve must be within 2% of factory specs... - Pure Stock Muscle Car Drag Race rules - link

I've read this before and question the whole validity of this "Certified Stock" claim when the fact is Bob's cam doesn't fit these guidelines. That and the fact that the guys who came up w/ these rules still jack around w/ the cams' LSAs as if that doesn't make a huge difference in how the engines run & idle. It's just a bunch of ego-driven crap to me...

Brad:

As much as I like those guys over there and its a lot of fun watching those cars run, I have to agree with you 100%.

... 383-4 stock 11" converter and 3.23 gears. Weight of the car is about 3900 lbs with driver. Car will be used mainly for cruising, but perhaps sometimes for stop light races too, if some ricers are coming to challenge the Challenger and starts burning tires beside.

So what would be YOUR recommendation, what cam to use in this 383 Magnum?

The rules of the class are also consistent with anyone using an otherwise stock engine.....stock unported heads, manifolds, etc. etc. So while Bob's cam is designed for PSMCDR, it works very well in any otherwise stock B or RB engine. Are there better cams out there? maybe,but if you plan on using manifolds, etc. I would imagine his works as well or better than anything else. After all he spent the last 41 years figuring it out!

As far as the rules go, if you read the whole thing, his cams are PS legal and NO, they aren't the same as the stock cam that was installed back in 1969.

As I said earlier, I don't care what the specs are (though I have no issue with those that do), all I know is all the fastest PS cars use his cam and it WORKS. 12.09 on bias plys? I thought Jim S. even ran an unofficial 11.97......that's all I need to know.

The Vodoo 220/226 @.050 with a 475/494 lift, 112 lsa really really surprised me when i installed it, sound near stock with a TON of mid range torque and power in the 2 to 4,500K range it does fall of at around 5,500 on my very stock 383 4-speed RR
