You have the car weight, frontal area, drag coefficient and speed, plug them in and get hp required.

Putting the plug in the transfer area will cause uncontrollable detonation in a race engine.
Hey guys! Check out the October 2022 issue of Hot Rod, pictures on pages 71, 73 and 74. See a Bonneville flathead. All the latest tricks like tunnel ram manifold, .470" lift roller cam, 313 cu. in., etc. 249.4 HP. BUT, notice it is not relieved! I repeat, NO relief!
Also note: In spite of all the modern technology, it is not anywhere one HP per cube!
