engine numbers
stamped on my 302 block deck just below the distributor is the engine assembly code.
My block reads 7H31R
Any body know how to read this?
I'm pretty sure the casting number above the starter (haven't taken it off yet to read it) is a EO something if I remember. I thought it was a 1980 something block.
Any help
Thanks
Dennis

Date codes
This is from the FAQs post at the top of the forum:
Decoding Dates
Date codes are sometimes included on parts. The first digit is the year. To determine the decade, refer to the part number's prefix. The second digit is the month. Note that the character "I" is not used. Refer to the chart below. The third digit is the day of the month.
Second Digit Month
A January
B February
C March
D April
E May
F June
G July
H August
I Not Used
J September
K October
L November
M December

So your date code would indicate 1987, August 31st.
