Yeah, each of us has his own "pet" engine size, whether it's in-the-flesh machines or just dreams. Here's one reason I can dream up a multitude of exciting projects limited to about 400 inches: Take a close look at what the Poteet & Main streamliner did at Bonneville last fall with a single 347 c.i. engine- a one-way run of 462 MPH, which is within ten MPH of the unlimited wheel-driven record!

I've always enjoyed Pontiac's "single V8 engine design of 287 - 455 c.i." since first messing with one in 1959.

Take a close look at that 347ci engines parameters and the design.

The Pontiac engine as designed as Milepost said, "Tweener". With the bore space limitation, comes the bore size limitation, then the cylinder head valve size. The original design was to move heavy street cars in a low RPM operating range. The Quest (no pun intended) for increased power will always come with a price, moving the RPM range higher. Bigger bores, shorter strokes, lower deck heights, compact induction systems. All of the requirements to go beyond the point we are today.
