It is a 232 cid engine. I do not know this for a fact, but I would venture to say that since our engines are supercharged they have a higher volumetric efficeincy than that of na 232s. With them being EFI, they would be near or past 85% (running at best). Now, since 232 is roughly 75% of 308, I have to wonder if there is a 10% correction factor to make it safe. Of course, this is all just my speculation.
