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

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.
I think (without referencing back) we deducted 4 tenths for any overbore. The thought was on the 318 race, if somebody went .030 over, the extra cubes is one thing, but most do it to raise compression. So, on a 318, if my stock 318 is a true 8:1, and somebody goes .030 over but uses good pistons and has 9:5 to1, they gained compression and cubes. That's why we deducted .4 tenths.
