Mustang and Charger

Strong Performance

This engine system is intended for the serious street rodder and muscle car enthusiasts. These system components will give you the ability to feel the power that was available in the great muscle cars of the mid to late sixty's. As seen on the graph below the horsepower is becoming substantially greater than the two systems before. The horsepower and torque are becoming close in number value but are spreading as far as peak rpms. This system is not recommended for towing. With the increase in horsepower the fuel economy is going to drop considerably from the previous system. With this system we recommend that you get more serious about the air flow in and out of your engine and the ignition system. Follow the carburetor and camshaft recommendations closely as these engines need to breathe to perform.

Recommended matching components:

  • Dual exhaust with high flow mufflers, larger diameter pipes and headers.
  • Torque converter in the 2400 to 2800 rpm stall.
  • High flow air filter.
  • Ignition upgrade - ignition box, coil, and wires.
  • Electric fan and pulley system.
  • High flow transmission cooler to accommodate the high stall converter.


Typical Horsepower and Torque results from an engine built from the strong systems and components list.
