Question Do you have to notch block for a 331?

Hey all,
Do you have to notch the block for a 331 stroker? And for the 347 where do you need to notch the block at? Which cyclinders, all of them or just specific ones?
Thanks,
Steve

My 331 is notched in all the cylinder holes at about the center of them.

Its not much just about the size of my thumb maybe.

I didn't have to notch mine for clearance, but I did it anyway to be on the safe side.

No notching here either. It will depend on which rods you have in it. Mine were close on the bottom of the cylinder walls but had "sufficient" clearance. A bigger H beam might have needed grinding.

Not all blocks need to be clearanced, so you have to mock your block up to know for sure.

This picture might help. Its a 347, but you'll get the idea if you end up needing to grind a little.
