350 = 5.7L, 305 = 5.0L, or if you have some block numbers I can run them.

105

should be a white emission label on plastic radiator cover under hood that says 5.0l or 5.7l. If it is destroyed or motor replaced, I look at harmonic balancer on front of crank shaft. If it is about an 1" wide it is a 350, 2" wide it is a 305. Also there are numbers stamped on a pad in front of the driver side head, that can be googled. Could be on passenger, side if older motor.
