It's from an 1979/80 small block 350, 4 bolt main. The motor is about to get cleaned, bored, and stroked before going into my 1965 Elky. http://65elky.g-rock.net/misc_images/gm_30.jpg There is a "30" on the left hand side of the GM and block main casting number. What does "30" stand for? http://65elky.g-rock.net/misc_images/misc1.jpg Two sets of "dials" or something. What do these mean? http://65elky.g-rock.net/misc_images/misc2.jpg In the timing cover area. "512 32" "020 509" "010" Please click on the links above to get the best view of what I am talking about. Again, thanks for any input into this. - ---- Graham Wooden, R.H.C.E.
