Hey all. Not to steal the show or anything, but I've been wondering pretty much the exact same thing as Danny -- I've got a 65 C10 with the 230 in it. Everything is original, but it just seems to really work the motor on the highway. Is highway speed too much for that motor as it is stock? Or am I just not used to hearing what a stovebolt sounds like on the highway? Keep in mind this is the first straight six I've ever owned...
