Went to the track, one time, with my 66 Cuda. Made a pass. Back in the pits, a guy comes up to me, and says, "that engine sounds wierd, is it a big block or small block"? I tell him "neither, it's a slant six". Then as I open the hood to prove it, I tell him it's only a 170, not a 225.
PS that run was a 13.4 at about 95 mph. But I do have more then $2,000 in the car.
