Add 273's, 340's & 360's to the "318 Race" ?

Good topic, and thanks for bringing it up. Is there an advantage if the cubes are no larger than a 340 +.030 or .060? Should there be an "extra" deduction for the X block? Without arguing, let's let others chime in....
And rumble, let's us know why?
And Yellow rose, let us know why?

If someone is running an X block or a stock block way overbore instead of the .020-.040 clean up. Should be judged on a case by case. But a .040 and under is like 5-7 cid difference. A 360 42 cubes over 318 and is worth .5 wouldnt that make 5-7 cid about .06 ? Could round it to 1 or none.
