Hoping to get back to that topic on our 403 78 GMC soon. As I have the parts including a 454 TB. I was thinking last night. If a 350 chevy TB can handle the airflow and fuel to 6000 rpm's on that 350 engine. Then why can't that same 350 TB handle a 403 at 4000 rpm's? As this engines are really just an air pump. A 350 at 6000 is pumping more air then a 403 at 4000. The intake valves and runners are about the same size. The 403 exhaust manifold is a little larger. The exhaust pipes are the same size. Anyone ever tried it?
