Need big block help

PRH said

It’s not a hemi block.
Heads won’t bolt on and they don’t have wedge style motor mount ears.

440-EZ heads are from Indy.

However, None of what you’re asking about will have anything to do with tuning the EFI.

I am aware that the EFI is totally separate. We were just doing detective work on the engine. I'll post the dimensions and dyno numbers from the builder soon, I didn't think they were looking like a 440. I thought maybe they stroked a 400 for him but then I found the casting numbers. I'm just not up on my big block stuff, but learning. thanks
