Re: [Chrysler300] do i have to use teh 268 cam???????

[Gary Barker <gbarker@xxxxxxxxxxxx>]

Don't forget that almost every engine on the road today built in the 
last 10 years have Ram tubes.  With carb's or fuel injection.  Just 
start opening hoods.4cyls to V/8s  they all have them.  So what I would 
do is take advantage of the Ram tube torque range. The 300F engine used 
a different timing gear. It retarded the cam 2 degrees.  Now we all know 
that retarding the cam extends the torque range.  I have always felt but 
not confirmed that Chrysler new the Ram effect gave great torque but for 
a short time, So if they retarded the cam 2 degrees it would extend the 
torque range a little farther.  Make sense?   
Now I don't know that much on the 300k timing gears  A parts book might 
show it. but If it were me I would install your cam so it would do the 
same thing.  The drawback of larger cams is loosing vacuum at Idle.  
Heater and a/c controls don't work right.  Power brakes won't work 
right.  Believe me I know from personal experience.   One other thing 
you might look at is your Torque Converter.  it helps make your Chubby 
Little Girl more drive able at slow speeds when you go to a bigger 
cam.      One mans Ideas-   Gary Barker
