On The Dyno

We set out to bust through the typical 400 horsepower range of a usual street/strip stock stroke 360, and went into our dyno session with 500 horsepower as the bogie. With a basic bottom end and a moderate hydraulic flat tappet, we were definitely holding back as far as high-end race parts, but the ace up our sleeve was that deep-breathing set of Airwolf cylinder heads. We ran the valves to set the preload on the hydraulic lifters to a quarter turn past zero lash, and dialed 34-degrees of total timing on the damper for the initial fire-up. The 360 lit at the first crank of the starter, and we put the engine through the normal break-in cycle to bed the rings into the slightly used bores, and get the camshaft familiar with the lifters.

Our first full throttle pulls had us handily over our 500 horsepower goal, with outstanding torque throughout the curve. Tuning with jet and timing loops showed the engine favored a lean reading on the lambda sensors, indicating very good fuel distribution. Our blow-by meter showed minimal leakage, confirming that all was well. We homed in on a best timing setting of 37-degrees total, and watched the power rise a few numbers with each pull as the rings mated with the cylinder walls. It wasn’t long before the 360 was ripping repeated pulls showing 522-523 horsepower at peak, and an outrageous torque peak of over 495 lb-ft. Even pulling down to a low 2,500 rpm, the 360 had plenty of shove, registering 375 lb-ft of low end torque. With power like that, our Airwolf-equipped 360 has the muscle to make the competition howl for mercy.
