A NEW BEGINNING

If we consider the 1955 Chrysler C300 as the first link in Chrysler's performance heritage chain, then 1962 would certainly have to be the second link. The 1962 "Max Wedge" (short for Maximum Performance Wedge engine but named Ramcharger at Dodge and Super Stock at Plymouth) 413 RB-engine was, most certainly, the "shot heard around the world".

Based on a regular production 413 RB, the Max-Wedge engine received everything needed to become a dominant force on the drag strips and streets of America. Beginning with a beefed-up bottom end with some of the best connecting rods ever developed for the B-series engines, the Max-Wedge proved nearly bullet-proof. High-dome pistons brought the compression ratio to an unbelievable (for the era) 11.0:1 and 12.0:1 with horsepower ratings at 410 and 415, respectively. Cylinder blocks required an "eyebrow" notch at the top of the cylinder bore to clear the huge 1.88" exhaust valves in cylinder heads with the largest intake and exhaust ports ever found on a production engine. Solid lifter camshaft profiles were also among the most radical ever to be put in a production engine. Topping it all off was a Ram Induction/Cross Ram intake manifold with dual Carter AFB 4-barrel carburetors. The racing world was literally turned on its ear as these behemoths were routinely driven to the track where they eliminated most, if not all "competition-only", and usually trailered opponents, and then were driven home.
