Agro1,

This thread sould be in "small block talk". Your question is an interesting one. There is no fast answer. You are on the brink of the whole BB vs SB argument. And I mean that in a good way. But I don't really care.

Let's keep things in context. My motor is anything but "sweet". This is not a street motor. I can spin it to 8500 rpm but I don't want to make power there. little motors have to spin to make power. The rotating assembly is zero-balanced which reduces stress at high rpm. Yes, wheight and how the engine makes hp and torque is why I went with my combo. If you just want to make big hp and torque well then by all means build a bigger motor. Much easier. There is much to consider when you start thinking about how you want the motor to behave. Yes, the more revolutions per minute, the more wear & tear. But so what. The term is called "freshening"

Think about why motorcycle engines are made as such. 289 vs 427. It's a great topic.

Help Simon. He's in the UK and needs a motor.
