Sissell Automotive ,who builds winning oval and drag racing 292 Chevy's claims over 600 hp on the dyno for its most radical non supercharged engines.The engines are 301 cubes, 5 liters.Their shop is in Baldwin Pk Ca. Give them a call .A drag racer, Jim Hendrick, drag racing a 3500 lb car, took several National titles running low 10's with a naturally aspirated 292 Chevy on gasoline.He had to have 500 hp at least.I don't know what to make of those claims, but must be some truth to it.
