*Dyno-tested at three locations, the prototype posts 464 HP and 479 lb-ft while honoring late-’70sPontiacheritage*

Texas fabricator and Pontiac specialist Ted Fox today announced the Mighty Mule, an experimental reinvention of Pontiac’s late-’70s V8 architecture that has posted jaw-dropping dyno numbers in prototype form. In tests conducted at three separate facilities, the Mighty Mule recorded 464 horsepower and 479 lb-ft of torque, a dramatic leap from the stock 1979 Pontiac 301 V8’s approximately 140 horsepower and 240 lb-ft of torque.

Engineered with re-designed internals, modern materials, and 3-D printed components, the Mighty Mule is built to showcase what’s possible when classic platforms meet contemporary design and manufacturing. While inspired byPontiacheritage, the experimental package is being developed with cross-platform compatibility in mind, including potential applications beyondPontiacand even select Ford models.

“The Mighty Mule started as a simple question: "what if the 79Pontiacspirit had today’s tools?” said Ted Fox, creator of the Mighty Mule and owner of Scooter’s Garage inTexas. “We set out to respect the look and soul of the late-’70s cars—but unleash performance that makes modern drivers grin.”

Currently, the Mighty Mule remains a prototype/experimental program while Fox explores the path toward limited production and parts packages for builders and restorers.

About the Mighty Mule (Experimental)

The Mighty Mule is an experimental performance program fromTexasmechanic Ted Fox, aiming to modernize classicPontiacpowerplants with contemporary engineering techniques while preserving period-correct character. Early prototype testing has demonstrated transformative gains over late-’70s factory output, with additional validation and development underway.

Question of the day for the experts: What sort of head, cam, and port design tweaks would you expect to see in a build like this?
