Oh boy the way Andy f used the 530 late 78 block and put around 800 HP down.
So year it's a matter of using a good block vs just assuming by casting numbers
I’ve followed AndyF for years now. He’s got a really impressive 470. I state in the video that all the 400s are great to use. I just emphasized the 230 CWB for its obvious benefit. I even mentioned the need to sonic check it.
