Chevelle SS396 Dyno Test - Calling Dr. Dyno!
|
After an aborted first dyno pull that forced us to adjust the Quadrajet, the Rat thumped out 199 horsepower and 274 lb-ft of torque. Knowing that the car was lazy through the rpm range, we added 8 degrees of timing, bringing it up to 50 total. The result was the big-block waking up from its slumber, and the Quadrajet-equipped powerplant cracking off 205 horsepower and 284 lb-ft of torque. Just by adding timing and making sure the Quadrajet was tuned, we gained six horsepower and 10 lb-ft of torque without replacing a part. View Related Article
