One thing leads to another... mean 318?

No, I’m not agreeing with you on this. If I was, I could say throw a 4 inch arm in a 273 and it would kick ***. It won’t. The BORE is too small. The stroke won’t do anything.
You sure did agree with me. OR you can tell me how a 273 will out power a bigger 318 engine when equally equipped. How does a 273 out power a 340?

How does a long arm crank not add torque and thus HP?
