Re: [Chrysler300] Gear Change

["Gary Barker" <gbarker@xxxxxxxxxxxx>]

I have a 69 Dodge Power Wagon ,383 4 speed. with 3;55 gears and taller tires 
than stock.  The factory Cam reached its peak Torque at 2800 RPM.  which was 
72 MPH.   So I had Crowler Cams grind me a Cam which reached its peak Torque 
at 2500rpm which is 65 MPH.  When driving empty or no load I could not tell 
the difference. But when I put my trailer on or a heavy load the truck 
performed so much better I couldn't believe it.  I live in Mountain country 
and go up and down the High Sierras .  I pass almost everybody going up 
Donner Summit. ---Thanks to Oky Bob for the Rear end Gears     Gary Barker
