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.

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!

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.
