Re: Flathead valves and flow??
Yes, 404a , 425 and a schneider cam.
404a works best, with wide powerband, but is alot of work to set up. I havent used a 1007b or L100 in a big motor , but i think it will work as good In a street engine ( around 4000 -4500 rpm) without all the hassle with big valves , porting And drivetrain setup (spring preassure, valve grinding,etc) Flathead engines are torque engine , not rev monsters. |

Re: Flathead valves and flow??
I have an L-100 in a 296 I built 15 years ago, Driven on the street in front of a C4 got great mileage on the road. Owner was pleased with the preformance.
