1970 plymouth & dodge service manuals both state that the '70 e body 383 4bbl (non-HP;330hp;blue) engines shared the same cam & valve springs as the 383 4bbl (HP;335hp;orange) and the 440 4bbl (HP;375hp;orange) Is there any evidence &/or proof that the service manuals are both wrong?  Nick

Below is a paragraph from the Mopar Performance 'Mopar Engines' book; pg.277.
John, there is one or two valuable threads here on Moparts the past few weeks that the guys have offered up alot of info and with factory documents, sales ads, and much more concerning the 1968/'69 B body 383 4bbl's.
For whatever reason(s) - Mopar decided that ALL 1971 383 4bbl's would share the same 440HP cam.
It would not be too far off to speculate that this same decision had taken effect after 1969; and for the same reason(s); only it began with certain chosen models - like the new for '70 E bodys (B/J) and the other 'perfromance' models (R/W.)
I would take ANY info in the mopar engine manual with a HUGE grain of salt , afterall they state all late model big blocks are THIN WALL castings and that has been PROVEN FALSE .  ...

I think that info posted on that page is INCORRECT , didn't the 70-71 HP cam have MORE lift ???

The info is either correct or it isn't. In an attempt to shed light on this subject - factory literature can be presented to use for corroboration of any witnessed testimony.
Fact: The 70-71 parts catalog lists (2) cams for the 383 4bbl in 1970.
Fact: The '70 service manual cam info above also states there are (2) cams for 383 4bbl.
Fact: The first of the two cams for 383 4bbl is specified as being the 383 2bbl cam p/n 2532190; .05 raised ring version; and installed only into the Fury and Suburban models - or Plymouth's 1970 C bodys.
Fact: Translates that all other 383 4bbls in Plymouth's line of '70 B & E bodys were given the E body 440HP p/n 3512907; non .05 raised ring.

A clue is in the parts catalog's denoting that the HP valve springs were given to all '70 B/J/R/W 383 4bbl's and that standard valve springs were excluded to D/P/C 383 4bbl's. When building an engine is wise to match cams to springs and vice versa. Consequences against are broken valve train parts.

that PARTIAL page of a 70-71 parts book doesn't say , aleat the part you posted , that the 2bbl cam in a 4bbl motor was only used in C Barges also take that COMBINED parts manual with a LARGE grain of salt , or does anyone have any PROOF that in the beginning of the 70 model year that chrysler was putting out 70-71 parts manuals ????  oh and something is not right , NHRA doesn't list the same cam lift spec for the 330 HP 383 as the 335 and the 440 HP's , NHRA is GIVEN THAT INFO BY CHRYSLER

John. I agree. Revert back to the service manual specs/legend to see that ONLY the Fury and Suburban 383 4bbl's use the 2bbl cam.
Second, research a 1970 Dodge service manual, what cars does it exclude?
Next, check a 1970 Chrysler sevice manual, and what cars does it exclude?
There appear to be quite a few 1970 Dodge & Chrysler models that are also excluded, not just Fury and Suburbans made by Plymouth.

Yes, I believe there was a parts catalog created for 1970...exclusively. If I had one I would refer to it as well.

While that may be true, the cam specs do not agree with the service manual specs and NHRA 'factors' both 1970 383 4bbl engines THE EXACT SAME.

I only have one cam BradH, the one that Ma Mopar installed into it June 1970.
Did you have anything that you can add to help our Mopar community find any answers as to which cam it was that was put in? 
Since you have the cam get us the specs instead of beating this oh so DEAD HORSE to death , ACTUAL cam TRUMPS VAGUE documentaion ...

The 1970 Plymouth Service Manual covers A, B, C, & E-bodies in one manual, where Dodge took 3 manuals to cover all four body types. SO .... according to the manuals a 383 4bbl Challenger SE (JH29N0) would have a different cam than an identically optioned 383 4bbl Barracuda Gran Coupe (BP23N0). THAT'S NOT THE CASE, it just isn't that simple. IMO ... the HOLLEY 4bbl topped ORANGE 383s received the HP cam!!  ............... the CARTER 4bbl topped BLUE 383s did NOT!! Mistakes & lack of accuracy in 1970 leads to confusion and uncertainty in 2009!!

I agree. Weren't you compiling all the various '70 383 engine assembly codes cross referenced to carbs, trannys, A/C and emissions?
Seeking:
1969 St. Louis plant VINs, SPD, and VONs.
Over 2,000 thanks to you!
