A12 “Mr. Six-Pack” Camshaft...
      #4138488 - Fri Jan 25 2008 05:16 PM

I spoke with Bob Karakashian on the phone a couple of weeks ago, and man! What a great Mopar enthusiast to talk to. From my experience over the phone, Bob is a very humble down to earth person to work with.

I called mostly because I’m very interested in his special cam grind. All I knew up to that point was that the Factory-Appearing-Stock-Tire (F.A.S.T) racing class that Bob runs his A12 Super Bee in, turns 12.09 seconds in the quarter @ 114 mph. And he does it with the required factory HP exhaust manifolds, a full exhaust system, and skinny G70-15 redline tires. I thought to myself that undoubtedly, these real world numbers speak for themselves. I mean, these are not engine dyno numbers, or chassis dyno numbers, but honest to goodness real world street/strip performance numbers, and a true testament to Bob’s expertise in big-block Mopar tuning.

The “Mr. Six Pack” Cam-

The conversation I had with Bob about his cam was very interesting and informative. I wanted to know how his cam was developed. First, Bob briefly mentioned that he had worked for Chrysler, which in my opinion, he understated that fact. I’ve since learned that the magnitude of Bob’s work for Chrysler was that his A12 Super Bee was a test mule of sorts for Chrysler engineers in the early 70s. Chrysler tested a number of new at the time Direct Connection Purple Shaft cams in his Super Bee. Bob went on to say that after some time his stock cam started to go flat, which apparently the factory Six-Pack cam has a taper to them, which makes them prone to going flat. At that point he turned to the major cam manufactures and had their engineers’ custom grind him a cam for his street/stock application. After testing cam after cam, none of them worked as well as original cam did when combined with his exhaust manifolds and tight factory torque converter. He then went on to say that he still has a box in his basement that is collecting dust with all of those cams in it. Disillusioned with the aftermarket, Bob thought to himself; I’ll design my own cam. Fast forward to our phone conversation. Bob told me that the factory Six-Pack cam is a great cam and that Chrysler really did their homework with it. Although tight lipped about the exact cam specifications of his cam grind, he did tell me that for the most part, it does not have much deviation from the original Six-Pack grind. He also told me that his grind is ground on a 114 degree Lobe Separation rather than the stock 115. In addition, Bob put allowances into his cam in order to make corrections for the lack of a true 1.5:1 rocker arm ratio of the factory stamped steel rocker arms. He is required to run the stock rocker arms in his racing class. Bob went on to say that his engine has such a glassy smooth idle, that he can rest a cup of coffee on the air cleaner while the engine is running without spilling. Then peoples’ jaws drop when he clicks off nearly 12 seconds flat in the quarter mile. After a while, people stated asking Bob what cam he is running. Bob tells them that its his own design, which is then promptly countered with, can I get one of those?!?! Again, the word is humble. Rather than do what a lot of folks sometimes do in the racing world by keeping their work secretive, Bob is willing to sell a copy of his cam to anyone who is interested.
Bob said that he’s helped folks replace their Mopar 284, and 509 cams with his own grind resulting in more crisp performance in their street/strip applications.

At this point, I have no qualms about it. My next street/strip engine build will have the now famed “Mr. Six-Pack” cam grind installed in it. Stressing over the right cam is now officially over.

Kudos to Bob Karakashian!

Quote from phone conversation: Bob Karakashian- “Most any engine can make power on the dyno, but can it get your car down the track?”

Thanks Regan,

Farming, Mopars, Football, Trap... You sound like a class guy as well.

Apparently you have an experience with “Mr. Six-Pack”? Anything to add?

I have talked to Bob several times - I had a 69 gtx that was an A32 car that was going to get his cam but I sold that project and got into 67 chargers.

I talked to Bob in depth about his cam and the 67 440 hp motors and he really helped me out - my 440 auto car is going to get one of his cam's this summer and I am buying a cam for my 4 spd. car when I do it - I am seriously thinking about doing some pure stock racing with it.

He's just one of those people you don't run across very often and a mopar guy to boot

Thanks for the comments 383.

I just found this two-year old moparts.com thread from a general yahoo search. This was before I even knew moparts.com existed and was a member.

http://board.moparts.org/ubbthreads/show...part=1&vc=1

It's amazing to me that Bob K. of Mr.6pack Racing Engines has been, as it would seem to me, just under the surface of the Mopar world, getting notability primarily by word of mouth and the occasional magazine article. And although I haven’t been into Mopars as long as some, it's still has been about fourteen years for me, and I've never came across Bob K. cams. Of course I probably wasn't looking. All I ever see in the magazines is Comp Cams, Comp Cams, Comp Cams.

Sometimes I wonder if the world of Mopar can be equated to the Internet, the research goes on, and on, and on forever...

BTW, I’m strongly thinking about renting a U-Haul and moving out to Detroit. The people there are too cool!

Thanks for sharing your story with us. Bob truly is a great guy.
While attending one of the Pure Stock Muscle Car Drag Races with my buddy Tom's '68 Hemi Road Runner, Tom introduced me to Bob K. Tom mentioned to Bob that I was working on a '69 6BBL 4-speed Road Runner that would eventually compete at the Pure Stock Drags. He gave me a few tips, then we left. The next time I saw Bob he said, "hey Dave, how's that Road Runner doing?". I couldn't believe he even remembered my car, much less my name.
My winter project is installing one of his cams that I bought a few months ago. It will be interesting with a 4-speed.
A best of 13.30 at 106MPH with the Mopar cam is a good baseline. We'll see how it does with Bob's cam at the Factory Stock race in Martin Michigan in June.

I had some experience with Bob.. I met Bob at martin 06 at the pure stock/f.a.s.t. race, there where about eight a12s running and mine being the slowest 13.20s in the heat.. I went over and introduced my self and said man whats the secret all these six packs are running real good 12.70s to 20.s.. His reply was what are you running I told him the green a12 and he said that's a nice car I was going to check it out let's go.. This guy stopped what he was doing walked a couple hundred yards to my car asked questions and gave suggestions.. I heard so much about Bob he's a legend and here he is walking with me like he knew me for years.. Well with his tips we got the car running a tenth better that weekend. I proceeded to stay in touch with Bob and started talking about an engine for my car since I was hooked with drag racing now and wanted to go faster.. So Feb 07 an engine went in the works Bob would call weekly to update and just stay in touch. Normally his engines take about six month depending how busy he is but he got mine done in four because he wanted the car to be in martin..
Well I receive my new engine intake to pan we do the swap (no dyno time) run it for twenty minutes
change the oil take it around the block and man I hit it holy sh!!.. The guy knows how to make them run..

Bob is a true asset to this hobby and a good friend..

would his cam also be good for a 383 four barrel?

Does he do cams for other applications?

I'm wondering what cam to put in a stroked 360 with efi six pak that's going in a street driven challenger.

383 Yes! And I think he has two cams. One for an automatic and one for a manual. The manual being a mechanical cam.

360, No! I think he is strictly a Big Block man.

Yes I race f.a.s.t.. The short times are always work in progress I'm usually mid to low 180s and the car runs more consistent 11.90s 12.0s.. It's
a great package Bob built for me.. I drive to cruise nights 2 hours from my house go to the track click of these times.. The only maintenance
is changing the oil and a coat of wax..

Nice combo indeed. I am in the slow process of building my car for Pure stock. I have one of Bob's cams. I have a replacement short block and a replacement block plus regular 440 blocks. I am not sure which one to build, although I am leaning towards the replacement short block with assembly date but no VIN numbers. I am hoping for mid 12's, but who knows. I am racing a 14" tired car now, the G70's should be a real trip to learn all over again. I have 100's of street races behind me, but none in my A12 since 1974-76.

Don't ask, he won't tell you. It really went against my nature to go with something I couldn't quantify/compare, but the results and service speak for themselves. I can't wait to get mine fired up.

Yep. You're right. I just got a reply back (within an hour on a Sunday afternoon no less) . That's fine and I think I will go with it but I'll call him and discuss it first. I just want to be sure that it is going to be as good or hopefully better for my combo than the cam I have now.

Regarding small blocks Bob recommeneded a cam to a friend of mine who had it custom ground?I ended up with it after he sold the car and never installed it All I know is the cam works terrific. I have run a dozen different makes and model cams, this one is by far one the best. Loads of bottom end and goes right to 6K with ease.

Sorry if that was misinformation. I was just going by what moparts.com user (AZ-Nick) said. In the old moparts.com post I linked above, AZ-Nick said that he bought the 4-Speed cam from bob and that it is a solid cam. I don't exactly have a Bob K. camshaft catalog to reference that, so I took it at face value.

Neither does Bob, from what I've determined. It's all in his head so the "secret recipe" can't be stolen.

The PSMCDR rules for their Certification process states the cam must be within 1% of factory .050 duration and have the correct factory cam lift per NHRA stock class rules.

Given those rules, any "legal" '68-71 383-440 HP 4/6BBL engine cam should measure...
Intake: 214 @ .050" +/- 1% = 212 / 216
Exhaust: 226 @ .050" +/- 1% = 224 / 228
Max Lift: .455"/.470" (NHRA "blueprinted" lift specs)
LSA: 115

For factory stock, I think the only thing they will check is that you have acceptable vacuum at correct idle setting. I wonder if they they would do a tear down for class certification unless you are protested??

I'd expect that unless you are trying to get the car Certified (it's voluntary), there's something of a "don't ask, don't tell" thing going on re: how "stock" some of those cars' cams are.

However, given the constraints outlined by the rules above, I could still spec out something using modern lobes that could be worth a few ponies over the OEM cam of yours we measured.

I know it bugs you that Bob won't come up with the specs to his cam, but as far as the rules go:

http://www.geocities.com/psmcdr/rules.html

Lift and duration as well as adequate vacuum is the only thing tested. Several cars that have been Certified under the rules (voluntarily) run Bob's cam.

Is there something modern out there that has factory lift, duration and gets 16" plus vacuum? I don't know. What I DO know is that Bob has run a 12.09 and Jim has run an 11.97 using that cam and that is good enough for me.

I know it bugs you that Bob won't come up with the specs to his cam...



No, it really doesn't... because I know exactly what lobes he uses and could call up the same cam grinder right now and have them send me exactly the same thing as a custom grind for myself.

My point is - without going into any of the actual specs - his cam does not pass the Certification process as described above. If there are cars that run his cam that have passed it, then they weren't checking the cams very closely during the inspection.

BTW, don't anybody bother to PM me asking for the specs of Bob's cam. It's obvious it works well as proven by the number of folks who run it with extremely good results. If you want one, buy one from him... he's the one who figured it out.

I'm equally impressed by how smoothly his car idles with it... sounds like Gradma's 318 w/ "hot rod" mufflers!

Is there something modern out there that has factory lift, duration and gets 16" plus vacuum?



From a major cam company's Master Lobe catalog:
272 @ .004" / 216 @ .050" / 127 @ .200" / .454" (1.5)
286 @ .004" / 226 @ .050" / 134 @ .200" / .471" (1.5)

Compared to John D's OEM A12 cam (IIRC):
292 @ .004" / 214 @ .050" / 124 @ .200" / .449" (1.5)
310 @ .004" / 226 @ .050" / 133 @ .200" / .459" (1.5)

And I think he has two cams. One for an automatic and one for a manual. The manual being a mechanical cam.




That's kind of odd, considering the factory only used one particular hydraulic cam regardless of the trans type.




Brad is right, that is not correct.




Sorry if that was misinformation. I was just going by what moparts.com user (AZ-Nick) said. In the old moparts.com post I linked above, AZ-Nick said that he bought the 4-Speed cam from bob and that it is a solid cam. I don't exactly have a Bob K. camshaft catalog to reference that, so I took it at face value.




And that was a Good Face you got it from.....
Yes I did buy a 4sp Six Pack mechanical lifter cam from Bob and here is a Picture of the box that the cam is still in, I never opened it because I changed my plans and no one wanted to buy it when I tried to sell it.

You were right I did say it and here is the pic of the box......

Yes, I recall that you advertised that particular cam that Bob K. spec'd out for you. Did he say it was effectively a solid equivalent of his hydraulic cam, i.e. intended for the same application? Or was there something different about how he expected it would used?

I know this is supposed to be about the Mr Six Pack cam, but if I were to call Bob to pretty much try to get a custom grind, do you think hed come up with something? Or does he just stick with the cams hes been selling or...?

I, too, can echo those comments about Bob K. Very personable to speak with on the phone and full of great ideas for a stock appearing and sounding big block.

I have one of his cams for my project and can't wait to see how it performs. I pick the engine up this Friday. :-)

I have a hydraulic cam from Bob that I purchased for my Six Pack Bee. Before I got around to installing it, I purchased another for my 440-6 Superbird, which I did install. I am now getting ready to get back onto the Six Pack Bee and Bob told me that the cam that I had would take more converter, which would make it harder to 60' I purchased another cam, which is what he is running now. I would think that the cam I didn't use would be good for a 4 spd or for street use with a slightly higher stall converter than stock? I have the spec. sheet for that cam. The other cams are classified.

I told him I wanted one of his cams ground for a 4sp solid lifter set up, engine is a 71 Six pack and he said that I would be amazed at the power this was going to have. He also said that he grinds Hemi cams too.....

I have a 69 RR 4 spd car. I don't have a 383, but I do have a Hemi and some 440's. If I go with a 440, I will use the extra cam myself. If I go with the Hemi, I will try to sell it. I have to finish the Bird,the Bee, and the Dart, before I think about working on the RR.
