413 Wedge
The other thing about any RB out of a "truck" is it might be a med/ heavy truck engine such as 413-3. These are easily identified by the "high" mount water pump and WATER PASSAGES into the fronts of the heads, which light duty/ car/ HP engines don't have. These engines do NOT use an exhaust heat crossover, but rather HAVE COOLANT in those passages. Many have a water temp probe in the exhaust manifold between the middle two cylinders on one side.
Basically what you have there is a crank and a block. Watch for 8 vs 6 bolt cranks as well
Below notice water pump casting connects to ports in the front of the heads
Below notice the water temp sender in the EXHAUST MANIFOLD. This is a water / coolant passage
EDIT Also notice the exhaust uses a different bolt pattern and will not accept "normal" B/RB header flanges
