ho-hum
It is boring to read about a high-performance unknown power plant in an unknown vehicle in a forum about "normal" engines in pre-73 Chevrolet trucks.
It is less interesting than learning about an Advance-Design truck with a
diesel engine producing 505 horsepower and 885 pound-feet of torque and it has 8-inch stacks ?
Ah, but, the original question was about larger pipes; so, this is still on topic?.
