413 Max Wedge Camshaft Specs: Ramcharger and Super Stock
Let’s take a look at the 1962 413 Maximum Performance (Max Wedge) engine camshaft specifications.
The 413 Max Wedge engine had a cam duration of 300°, 75° overlap and a lift of .509″ intake and exhaust. The camshaft used flat-faced mechanical tappets.
Plymouth and Dodge both had their own versions of the 413 Max Wedge. The camshaft and other specs were the same for both engines.
Plymouth called it Super Stock 413 and Dodge called it Ramcharger 413.

The Dodge 413 Max Wedge Saleman’s Guide
The camshaft specifications are typical for racing applications. The Dodge salesman’s guide from 1962 stated the following about the camshaft idling and quietness:
The long-duration camshaft provides maximum power output at the expense of smooth idling and low-speed response. Similarly, increased piston clearance and the special valve mechanism allow dependable high speed operation, but sacrifice some of Dodge’s customary engine quietness
In other words, the cam had a lopey idle, sounded awesome and got the car moving quickly!
The mechanical valve lifters replaced the standard hydraulic design. This eliminated pump-up at high rpms.

About 38 years ago I assembled my first Mopar engine. It’s at that time my hands on experience with Mopar engines, including the Max Wedge, started. Although my research of the engines started years earlier.
