I doubt that anyone has reached the 200 hp mark with a normally aspirated flathead. using regular gas (91/93 oct). The reason I say this, is: the ports wont pass enough air. They come close but at around 48/6000 RPM depending on displacement, the ports shut dowm. I built a 294 blown engine for Ron Horrell to replace the 296 engine I build 15 years ago. Using a Magnason /Eaton blower his engine produced 235 HP ay 4500 red line. With 5 lbs of boost. It also produced 300 ft /lbs or torque at 3000 rpm with 3 pounds of boost. I would suggest that if anyone makes a new block he work on the intake port allot. Must get rid of the bowl.
A garden hose will only pass so much water, with mother nature pushing on it.
