I finally located the numbers struck onto the block and there were 2 sets of numbers.
They were stamped onto the passenger side (facing front of motor) on a ledge just infront of the valve cover.
It reads like so:
C5A146997 V0507TJH
From the info I could find after searching online I got the 2nd portion semi decoded from this site
http://www.thedirtforum.com/gmcastingnumberlocations.htm
V= Flint Plant
05 = May
07 =Day
T = Tonawanda Assembly Plant
but the JH part I couldnt find info on the site listed above
This site mentioned the suffix code on this page
http://www.nastyz28.com/gm-chevy-codes/chevy-engine-codes-suffix-7.php
but there were 2 entries for TJH and the years were 73 and 76, both showed a 350 type so I am pretty sure its a 350 but from what? Maybe it doesnt matter a bunch but as I try to get the transmission figured out it might be handy to know.
The 1st set of numbers "C5A146997", what is that exactly?
There was also a number on top of the engine right in front of the distributor
88766954
GM8
Trying to learn what these numbers are referring to and to double check my research and ask the pros here.
