This is an NHRA stocker....... I always get a kick out of the power numbers from the calculators. Most good running stockers run better than the calculators predict.
The motor for that combo makes 495 corrected flywheel hp. The Moroso slide calculator shows about 530hp, and the owners electronic ET predictor shows like 545.
The car must ROLL very easy
