If an engine builder wanted live on the edge, they could take a 350 block and offset sleeve all eight cylinders with chrome-moly sleeves and have greater clearance between the intake valve and cylinder wall. You might even then put a larger intake valve in the head. If that allowed the port to flow more air, you might find some power. They might even go to the trouble to make a deck plate to accurately locate the bores off the head dowel locations.
I wouldn't know anyone who would go through that much trouble....Would I?

I know somebody who did EXACTLY that......................and his name is Jerry Ault. A LOT of work. Jerry was a magician when it came to engine building. I actually found one of his old race engines last year and I "plan" to put it in the car this winter along with a Doug Nash 5 speed, but my back surgeon may have something to say about that.
