268/272 and .444" on both intake and exhaust is the Reproduction spec, IIRC.

Dunno if that helps.
 
'68-'73 340 .430/.444 lift 268/276 duration...the '68 340 with manual trans. was .444/.453 lift .276/.284 duration...
 
that sounds about right. read it somewhere. thanks.
 
Correct. It's Purple Shaft P4452782, or 340 Cam 2899206. Same grind on each: Lift 0.430in/0.444ex, Dur 268in/276ex. I'm told a good "bolt-on" combo for a 318 is (360 heads, P4120094 gasket, and this cam).
 
still a good thread
durations at SAE (.004 with 1.5 rockers) Crane used to have on their muscle cam, blueprint line but I can't find it>so here is ELGIN E578S
cam lift .286/.296
valve lift .429.444 1.5 rockers

duration 279/289 SAE so compare with Crane/ Cam Dynamics and others that advertise at .004 Summit
.050 209/220
8 37 46 -6 Timing @.050
50 overlap at .050 SAE method

Elgin has a dozen cams for the LA
Elgin Industries
do a spreadsheet if looking for a cam and figure out the intake closing point
other places have the timings at advertised
don't pay for just a name on the box
 
I agree. What the heck, its been revived, whether by a spammer or whatever, might as well update it.
There's prob some small difference in the factory cams or they wouldn't have changed the p/n. And any replica cams could be based on any one example and the points measured.

Chrysler
2899205 1968 Manual Transmission
2899206 1968 Automatic Transmission
2899206 1969-1974 (340 & 360 with 4bbl per 1974 Dodge FSM)
4214671 (1974- 1976 360 E58 package internet info. FWIW)

P4452782 Mopar perfomance 340 replacement cam
P4452782AE Newer Mopar perfomance 340 replacement cam

FWIW Here's what's in the FSM's for the 340 cams. But Wyrmrider and others have pointed out these are not SAE numbers.

Crane
WG-1118 Blue Racer replacement cam

These are the numbers that are in Dynomation for Crane's 340 "Blue Racer" replacement cam. Note its based on the E85 package cam which I don't have factory FSM specs for. If someone has that would be interesting.

Elgin has quite a few good ones. Along those same lines, I used to sell a lot of TRW cams back in the day. They had a real powerful 300°/.500 small block Chevy cam that the bowtie guys liked. Nothing wrong with a non-big name cam. Comp isn't the only answer.

Are the 4bbl 318/360 pkgs from '77-88 the same E58 cam?

I'd heard that but now have serious doubts about it.

Web info only here, but think its basically correct.
318 4 bbl ELE Police package came with cam p/n 4227879
and that might be different than the 318 option E48.
I don't have or know of truck or car references for the newer stuff.
Possibly there are truck and FMR or Police car websites with factory info. ???

edit: FWIW.
Larry Shepard's book lists that cam as 80-86 318 w/4BBL
Hot Rod Small Block Mopar Engines HP1405
and some of the on-line Chrysler dealers show it as '84 - 89 318 diplomat
Dodge Diplomat Camshaft - Guaranteed Genuine Dodge Parts
or 86-87 van
Camshaft - Mopar (4227879) | TascaParts.com

List in larry's book is prob same as in DC speed bulletin and Speed Secrets books.
In any event it does show a 360 4 bbl cam, 4041998, having similar lift and duration to the earlier 340/360 cams.

All the same- vendor changes and maybe computer smoothed Remember Crane bought one of the Big Detroit grinders (and where are they now?)
All ground by a big Detroit grinder no mater who you get it from
nice reminder of the Blue Racer line and excellent catalog
note the 268-276 number is just an identifier for the factor replacement- it has no basis in reality but is close to .008 so compare with Racer Brown or Engle or others that use .008
.the SAE .004 posted above gives you a hint on how long the ramps are (especially on the close)
I consider this cam to be wholly obsolete for ANY BUILD
what started out as a performance cam for a high compression motor with excellent wear-ability and low warranty claims- (I was there as a service mgr then) morphed into a smog cam for low compression motors

Thanks.
So to summarize what your saying, the following cams are essentially the same.
Maybe some small differences in grinding the shape, matl. or manufacturing.

Chrysler
2899206 1968 Auto, 1969-1975 340 & 360 with 4bbl
4214671 1974- 1976 360 E58 package quoted by @moparmandan 360 Stock Cam Spec's.?
4041998 1976-80 360 w/ 4bbl [E58 ?] in Shepard linked above.

Mopar Perfomance
P4452782 "340 replacement cam"

Other brands
Crane Blue Racer WG-1118 [specs shown in dynomation screen shot above misinterpreted Chrysler for SAE method]
Elgin E578S
Crane 963901
Cam Dynamics 15002
TRW TM578 sp-cs 644
Wolverine CS 4109 marine ?

Chrysler LA HP/4bbl hydraulic FT cams different from the above:
4227879 1980-1987 318 4 bbl [E46 or E48? & Police pkg?]
4042000 1976 -79 360HP [Calif ? E56?]
 
IDK about any use in 318 would have to check the shop manuals IDK the 4042000 or E56 dig out the shop manuals
chrysler would change numbers when changing vendors
there is also a reverse rotation marine
wolverine is WG
Cannot find Crane Muscle car or blueprint series on line anymore
IDK about cam dynamics before or after buy out- they had a cheater IDK about blueprint EDIT CAM DYNAMICS IS SAME AS CRANE

Here is what the 2899205 68 manual cam sounds like:

Please note my mufflers are closed, in other words, in the quiet mode.

Please note my mufflers are open, in other words, in the loud mode. I have a Dr. Gas X crossover so it tends to smooth it a bit. it is pretty crackly and snarly for a stock cam when it has no crossover. This cam picked the car up about a mile per hour so it is likely worth 7 to 10 HP up in the 5500 to 6000 rpm range. It is truly a great cam for a stock four speed car. Set your volume levels the same and you can then hear the almost 10 dBa difference between open (this one) and closed (above).

Sounds great Tom. Idles just about like the Racer Brown solid I have in my 408
 
340 HP CAM here you can compare MOPAR duration which is close to .008 with .004 data
