Still loookin through loose catalog pages...

 

[MOPAROFFICIAL]

Probably one of these

Some basics of cam design make me think of this cam as one cut for high torque ( power coming off a corner in oval track racing is extremely important) and a large cubic inch motor.

In typical Mopar fashion, the description of the cam has the 265/275 @.050 specs, but in the chart it has the #'s I posted. Best guess I suppose!

Do you not like the MP grind?? I must,say when I looked at the numbers it made me giggle. I like it by the numbers. I just wouldn't lash it looser than .021-.022 hot.

I’m asking because I could not find any info on it.

Thanks for the lash tip.

I see Dartfever has the book! What book is that in?
Thanks.

MPoffical, thanks for beating the books and presto! An internet page with one for sale????? Holy Moly!!!!

Greg, it is also the cam MP recommend for the 9:90 & quicker bracket. I’m down to cam, rockers, springs & carb for the engine.
Converter, wheels and slicks plus a cage with “other” body work.
(A zero rush project.)

Found it in the 1996 Mopar Performance catalog

DANG! It gave that one away years ago.
Well, at least it went into good hands. A budding young MoPar man! Lost his mind with the “Tips” section.
Thanks again!

Now, who cut these cams back in the day?

Crane? That’s what I believe.

 

[dartfever]

Pretty sure it was crane. I know the original R/T cam they were selling for the magnum engines was/is a crane grind. powermax 2030 IIRC. So I would assume they did their other grinds too.

 

[Bighead440]

MoPar's published specs are always random numbers, best to have it "Cam Doctored" by Oregon Cams or someone who can give you a printed-out analysis. I saw these cams on Ebay and figured someone was in for a Columbo phase prior to degree-ing them, etc.

 

[rumblefish360]

It do not own the cam.
