RE: Chevy or otherwise, makes no difference.

All water-cooled engines have a coolant bypass either interally or externally. It works the same on any Chevy as it does in an FE since the design intentions are exactly the same. If your trusted mechanic is doing this to small or big block Chevys, Mopars, or Ramblers, he's just as wrong and as big of a dumb-assed Bubba as you're going to find.

The purpose of the bypass is as noted -to circulate the water in the block for a faster, more even warmup thoughout the entire engine. It also has a secondary purpose -to keep the engine from doing a China Syndrome. If the T-stat sticks, the temp will come up gradually and give you enough time to note the problem and get yourself off the road. Without the bypass, no coolant is circulating and the engine will go into a near immediate meltdown.
