 Topic: Hi perf factory camshaft part number?Posted: Feb/16/2016 at 5:34pm |

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. |

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 Probably another case of part numbers being superseded or amalgamated.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.

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 Superseded part numbers are fair enough, it is not worth turning the entire forum upside down tracing the evolution of old part numbers, but was there ever an early and a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.

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.

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