I just bought a cam and kit, original AMC still in the box. It is part number 19.140 or #3208586. Box is clearly marked "hi performance camshaft kit". Anyone got a listing for this part number? Thanks!

I have found it. It seems to have been the part number for the group 19 cam and kit. What is confusing is that it does not match either the parts book or the "dealer installed equipment" brochure. There is a separate part number for the 69 and earlier kit and the 70 and later version, at least according to the above factory references. In the real world was there two separate kits or did they just use 3208586 for all and let the adjustable valve train take care of any issues of different deck heights and pushrod length? Thanks!

In the book titled "Rolling Thunder From American Motors" page 48, There is an illustration of cam (1967/68) 320 8706 19.140 under HIGH PERFORMANCE EQUIPMENT GROUP 19. Same as (1969/70) 448 6169 19.140 No specs on the cam. ------------- Questions are powerful tools...what's in your toolbox? |

I have that same listing and that is what is confusing me. That is the Group 19 illustrated factory parts listing and the kits are listed as 67-69 and 70 and up. The kits appear to use all the same parts except for the camshaft itself and the pushrods. They both have part numbers of 19.140 but they also have two separate part numbers, as you noted above. All of the actual camshaft kits I have been able to see in the flesh all have part #19.140 and #3208586 printed on the box. I also have only seen one camshaft specs sheet listed, even though there are two camshaft part numbers. It almost seem like they had two sets listed on paper but in reality only one camshaft kit was ever actually produced. Probably another case of part numbers being superseded or amalgamated. Thanks! Chris

"They both have part numbers of 19.140.." This is the Group Number. Part Number for the Kit ('67/9) is 4486719 and ('70/'71) is 4488413 according to my 1967 - 1972 parts book. ------------- Mike |

See what I mean about confusion? Your part numbers match my printed factory information, but not the actual kits that were sold to the public. I have found a couple of references in old Car Craft buildups and other articles of the day that show the cam kit listed as #3208586. The original packaging for mine clearly shows both 3208586 and 19.140 printed on it. I guess my main question is this. Superseded part numbers are fair enough, it is not worth turning the entire forum upside down tracing the evolution of old part numbers, but was there ever an early and a late camshaft kit actually sold, or is this a parts book ghost? BTW, pardon my ignorance, but what is a "Group #" vs a "part number"? Each part seems to have both and it seems a little redundant. Thanks!

The Parts Book is divided into Sections called "Group(s)". Group 1. is Engine, Group 2. is Cooling, Group 3. is Electrical, etc. through Group 35. To find a part Number you must go to the Group number, then Section number, sub-section and then locate part name, the Series, year and any specifics (with 4-speed transmission = W4ST). In the case of the Cam Kit, the Group is 19, the Section is 140 and the part number 448xxxx. The Group and Section number are represented by the number/decimal (19.140). If there is a number after the Section that number denotes the sub-section. Something like: 1.037-6. ------------- Mike |

I should have said that I had a Cam Kit for the '67/9 but I don't remember the printed on-the-box Part Number but it did have the shorter pushrods. ------------- Mike |

| What is interesting is the pn is related to the big valve head suffix for '68/'69- 3188558-1 or -2. |

The only specs that I am aware of are a spec card for the Group 19 cam. It has been posted here before, but I will put it below. If you read the old CC articles from 1969 and other references, the kit is referred to by part #3208586 and as having .477 lift and 302 degrees duration. It is also referred to by detailed specs(opening/closing events, etc) in the Rebel machine pamphlet of 1970, though there is no part number given. Again, if we are enjoying chasing part numbers evolution for it's own sake, I am in, I love that stuff! However, my only real question is whether or not there were different camshaft kits by model year, or did they simply supersede everything to one part number and that is what the public was sold? I am inclined to think that would be the likely way to do it, saving more parts buying and duplication. I would guess that it was thought that the adjustable nature of the complete kit would take care of any issues of different dimensions between gen 2+3. Thanks guys for indulging my idle speculation!

Here are pictures of the box I have. I always assumed it was an early version ('67/early '68?) since it only listed the 290 and 343. http://s1116.photobucket.com/user/txamx/media/Gr%2019%20Cam%20Kit%202_zpsycyl6upm.jpg.html" rel="nofollow">  http://s1116.photobucket.com/user/txamx/media/Gr%2019%20Cam%20Kit%201_zpsl0iqmzrc.jpg.html" rel="nofollow">  http://s1116.photobucket.com/user/txamx/media/Gr%2019%20Cam%20Kit%204_zpsoz3qzgeh.jpg.html" rel="nofollow">  http://s1116.photobucket.com/user/txamx/media/efe589f9-e782-493f-b024-145673b5e291_zpsvvexxqkk.jpg.html" rel="nofollow">  -------------

txamx, Your box and mine look pretty much the same except for the stuff on the bottom. Mine only has the packaging companies logo there, nothing about engine displacement. Part numbers etc are the same. I am inclined to think you are right, yours is probably an earlier issue of the kit. Using a bit of reading between the lines, I can show the same kit being used in the CC "project Super Javelin" articles of 1969. Though it does not list the part number, the precise cam and valve spring specs are also listed in the 1970 "Rebel Machine Pamphlet", which would indicate to me that the factory intended the kit to be used in the 70 and up 390. The evidence pretty clearly indicates that this is the one and only camshaft kit that was issued for dealer installation. We don't have a definitive part number and tech bulletin, but all roads seem to lead to Rome here. If we had the part number crossover bulletin of 1969 I am sure they all go to 3208586 for the "Hi Performance Camshaft kit", regardless of model year and displacement. Thanks! Chris

In the "AMC Power Book" on page 20 there is a re-print of a 1968? "CARS" magazine article by Martyn Schorr title "Project Super Javelin" where they built up a 1968 Javelin 390. The parts list in that article includes AMC #3208586 Camshaft Kit. Greyhounds-AMX posted here a link to Google Cloud of a 1967-68 AMC Parts Manual including the Group 19 Section, but a couple pages are missing, 2nd & 3rd page iirc, page A-1 & A-2. Unfortunately I think the 67-68 Gr 19 AMC Camshaft Kit and Part Number are on those missing pages. Guessing 3208586 was the Camshaft Kit Part Number in 1967-69 or so and the Camshaft Kit Part Numbers got changed for some reason when they added the 1970 & Up version, 1967-72 June Edition AMC Parts Manual Group 19 shows 4486719 = 1967-69 Camshaft Kit 4488413 = 1970 & Up Camshaft Kit and ref in both of those Kits is included 3208568 Hydraulic Lifters and 3208569 Pushrods in the 1967-69 4486719 Camshaft Kit so it stands to reason the 67-9 Kit pieces are in the same part number neighborhood as the "early" 3208586 Group 19 Camshaft Kit. If someone has those couple missing pages A-1 & A-2 from the 1967-68 edition of the AMC Parts Catalog It would be great to see them and if it shows AMC Part Number 3208586 Camshaft Kit.

Thanks LRDaum, hope all is well, was sharing what I found trying to clarify the earlier 3208586 Kit Part Number which no longer shows up in later documents which instead shows 4486719 & 4488413. Looks like 3208586 is just an earlier pre-1969 AMC part number for the same kit. ------------- Link to a http://www.youtube.com/watch?v=MySiKQsmWxU" rel="nofollow - Short YouTube Burnout Video |
