Yeah, this is something I have thought about. Most people who have seen it have said it's a 250, although there was one person who called it a 256 or something like that - which I imagine is wrong. Like I said before I haven't actually had time to go over it very closely myself. How do I tell what it is? Are there any dead giveaways as to the difference between a 230 and 250? Also, it has an electronic ignition and the newer style oil filter. I wonder if the engine came this away or was just updated by the previous owner. I know it's not the original engine, because, as I said before, the previous owner destroyed the engine that was in it when he got it trying to push it too fast.
