also.. look on the pad in front of the passenger side cyl head for a stamping there as well...

if the engine block has not been 'decked' or surfaced, the numbers should be there.. it will give more specific details on the build date and location of the engine...

a little info on that....

Engine ID Code Example: V0101CLJ - (V = Plant, 01 = Month, 01 = Day, CLJ = Engine Suffix Code) I have more suffix code info if you need it
Another example: T0830CTY - (T = Tonawanda, 08 = August, 30 = 30th day, CTY = 1970 396 Camaro, 375 hp, 11.0:1, TH400)

Code Engine Plant
F Flint (Motor)
S Saginaw Service
H Hydramatic
T Tonawanda
K St. Catherines, Ontario (McKinnon Industries Canada)
V Flint (Engine)
M GM of Mexico

Casting Date
Small block casting date is located on driver side rear of block on flange forward of bellhousing. Big block on the right side of engine above the oil pan rails.
Casting Date Example: E038 - (E = Month, 03 = Day, 8 = Last digit of model year (1978)).

Month: A = Jan, B = Feb, C = Mar, D = Apr, E = May, F = Jun, G = July, H = Aug, I = Sep, J = Oct, K = Nov, L = Dec

I have more info if you need it....

hopefully you still have the stamped #'s on the front of the block... it will give you waaaay more info than just the casted number on the back...
