Pontiac V8 Water Pump Modification Tip Video V8TV "Routy" 69 Firebird
http://www.v8tvshow.com/69firebird - The Pontiac 400 V8 engine that we're
using in our 1969 Firebird project called "Routy" came to us completely as
a rebuilt long-block with all new parts inside, but we were charged with
the task of doing the final assembly and detail work. This time, we're
test-assembling the brackets and parts on the engine, and came across a
great tip to help keep your Pontiac V8 engine running cool.
