I do love them all 305/351/379/401/432/478 plus the 637 V8, and 702 V12🤩

Always thinking of ways to do it differently

Not that simple. 401 and up use a gear driven crank, 305 and 351 use a chain. V6 engines are not about high rpm horsepower, there all about low rpm torque. They all have heavy internal parts that like to run slow .
