Advice small block K frame with Schumacher conversion mounts for a big block

Trial fit it before cutting the notch for the oil pump.
I have done many of these conversations and every k frame is slightly different.

I had one k frame that didn't require a notch cut at all, the ear sat back far enough that it didn't touch and this was how it was from the factory.

Others I have done, the template didnt put the notch in the right place or the size of the notch on the template was off.

Best way is trial fit and mark where your notch is needed with a marker.
