1990 Ford Mustang Head Swap - Back In Business
On the dyno
The numbers don't lie. We worked with a Mustang dyno, so the output might be a bit lower than Dynojet results. RHS heads picked up this engine combination by 37 hp and 25 ft-lb at the rear tires. We particularly liked the Average Results-an increase average 47 ft-lb and 16 hp. All testing was accomplished with 15 degrees of timing and a warm engine. The air/fuel ratio was also kept consistent to ensure accurate results. View Related Article
