Re: Speedway’s Valve Train Components
Assuming these number are correct and they scale, that would be somewhere in the 1.5 to 2.5 hp range on a 100 hp flathead. That would be worth something on an all out engine using 200 hp and 3 to 5 hp gain, every little bit helps. But unless the price is right something you might be able to live without on a street engine.
