I thought the 3.07 ratio was strange as well but it’s the only mechanical option on my SPID. The serial number has an “S” in it so I know it had the 250. I guess it was made as a highway cruiser? I have a 292 sitting in a 70k mile parts truck. The only reason I was leaning away from the 292 is because I’ve heard it was a gas hog. It is a powerhouse but would it be a decent highway driver? This truck is my cruiser. My truck that has a 350 in it is sitting on i6 mounts so I don’t have to change anything but the exhaust, clutch mount, and few other things.
