Hi everyone,

I finally got arround to removing my valve covers and wrote down the numbers off the heads. Here's what I found:

333882
G21 76
GM13T

Any help decoding would be great!

Here is what I found on Mortec (I LOVE that site! www.mortec.com (http://www.mortec.com) )

333882.....74-80...350/400......76cc chambers

I'm guessing on the G21 76 being July 21st 1976
