Re: block question
There are casting numbers on the drivers side rear of the block, they will give you a vague idea.
One peice or two on the rear main?
Drilled/milled for roller lifters? (looks like it is.....)

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
