Build Date 24M

According to my book it was made December 24, 1958. The DATE on the door data plate says 24M
24 day of the month
M= December First Year (1958)

So the engine is a year older than the car. That should mean it definatly had metal wire combs on the valve covers if it was made in 1957 for the 58/59's.

Wouldn't it be a hoot if it was an engine out of a 1958 T-Bird 430 prototype! I wish.

Thanks,
