The Bible does not explicitly state the number of years between the Flood and God's call to Abraham. However, we can estimate the time using the genealogies in Genesis.
* Genesis 11 lists the generations from Shem (Noah's son) to Terah (Abraham's father).
* By adding up the ages at which each patriarch had their first son in that lineage, we get an approximate timeframe. This is subject to interpretation as there are different ways to understand and translate the ages given in the genealogies.
Based on the Masoretic Text, the traditional Hebrew version of the Bible, the time from the Flood to Abraham's birth is estimated to be around 292 years. Abraham was 75 when God called him (Genesis 12:4). So, the time from the Flood to God calling Abraham would be approximately 367 years.
Some interpret the genealogies in Genesis 11 differently. The Septuagint (Greek translation of the Old Testament) and the Samaritan Pentateuch have different numbers, which would lead to a different calculation. For example, using the Septuagint, the estimated time would be longer.
