I bought a 1966 Special, picking it up tomorrow. I had a friend who lives near the location of the car go and check it out for me, though, admittedly he knows nothing about Buicks. (He builds mostly mid-60s GM stovebolt stuff.) I got to looking at the pics he sent me and I noticed something odd under the hood. Let me preface this by stating that the seller swears it's the original engine to the car, which should be by all rights (in a Special) a 300 if it's a V8. I noticed the ring on the air cleaner said "Wildcat 350". Assuming it's the original air cleaner as well, was a Wildcat 350 actually a 340, since the Buick 350 wasn't introduced until '68? I've heard the 300 referred to as a Wildcat 310, only because I owned one many years ago, and I know it was based on the torque rating rather than CID or HP. Which leads me to my next question.. If the engine under my hood IS the original engine, which I've then got to assume is a 340, how rare is it to find a Special with a 340? The only mention of it I have been able to find online is in the pic posted below, but there is no info on how many were built with this configuration. I'm really just trying to figure out what I've bought here, though the best way to confirm anything will be to run the casting number from the intake once I get it home tomorrow evening. It'll at least identify whether it's a 340 or a 350 I guess.
