I have myself a 67 camaro convertible 250. I'm trying to find out if the inline 6 250 is original to the car. No serial numbers were stamped on block so I can't confirm that way. There is a code of 0810FM on the block. The FM suffix is corrrect for a 67 camaro. From what I understand, the 0810 means August 10th? .....but my trim tab shows my car 04A (first week of April). So that doesn't add up unless the 0810 engine code is referring to 1966. Is that possible? The car has about 80K original miles so I can't imagine someone putting an entire new engine in this.......especially another period correct six. Any input would be very appreciated. Thanks much!
