Tubular k frame seems overkill and very expensive for your performance goals. As stated above don’t worry about cutting the crank. I’m currently putting more hp/torque than you will through a cast cut .010 crank and spining it higher.
i know im not gonna have enough power to break anything its the principal though that im talking about, and i know the k member is kinda pricey but i need a new one anyway
