Mustang and Street Rod

Mild Performance

This engine system is a step above the very mild engine system. Although along the same lines, it is intended for the street rod and street car enthusiasts that are looking for more torque and horsepower, better throttle response and be able to cruise the highways with decent fuel economy. Since this system produces less torque it is only recommended for light towing up to 4500 lbs. This system can be used with stock pistons and heads and can run on regular to mid-grade fuel. We always recommend improving air flow in and out of an engine and with this system we recommend an ignition upgrade.

Recommended matching components:

  • Dual exhaust with high flow mufflers and larger diameter pipes.
  • Torque converter in a 1600 to 2200 rpm stall.
  • High flow air filter.
  • Ignition upgrade - coil and spark plug wires.
  • Adding an electric fan and pulley system can help optimize horsepower and economy.
  • Transmission cooler.


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