- 1974 Brown Coupe 454 4-speed
I have an unrestored 74 454 4-speed. Where exactly is the P number that tells you what ratio muncie you have along with the date it was built? Is it on the passenger side main housing where the US Patent markings are? I could not find it there. Is it rearward and downward from there and still on the main housing? Is the print much smaller than the US Patent print?
