Seams to me I've seen somewhere on here bow to tell he difference between the 272-292,and the 312. If someone could point me to that info I would be very greatful. I have an opportunity to buy a 56 CV with thunderbird badges on the front fender and I am hoping it has the 312 however I am not sure how to tell and the folks selling it have no idea. I was told it ran great when parked OUTSIDE 3 yrs ago. Its a complete car in fair condition. Thanks in advance
