If you're gonna stroke the small block, stroke the big block to make it a real apples-to-apples comparison.
Great thing about a big block is that you can make massive power with production pieces - large ovals for a strong street engine, rectangular ports for all-out and higher rpm power. Plenty of 468's running 10's and faster with factory parts. It generally takes some port work on factory castings, mind you, but it can be done.
A well-built big block will pass anything...but a gas pump
