So who in here races a 318?

I think he views it like;

It's a 318 in whole if the heads are used. Pure 318.

it's a 318 w/340/360 heads, a change and a move away from a all stock engine needing help in the breathing department. If the 318 heads aren't up to it, the engine may still have the OE C.I.D. but the heads, even though stock issues, are not stock to the engine as made. Not a pure 318.

Then theres stroking. Once stroked, you can't really call it a 318 anymore. Call it a stroked 318. 318 to ***.
