Clutch fan or Straight Blade only????
Hi Guys,
Finishing up the restoration on the 67 Firebird 400 /TH400 and thinking for a street car approx 330HP with stock radiator and shrould what would be the best fan assembly to use to keep it COOL. A fan ( 4blade 5blade 15" 17" ?? ) straight to the pully or a clutch fan (what size) and 4 or 5 or 6 or 7 blade .. thanks for any input. |

I'm running an 18", 7 blade flex fan from a '69 Caddy on my '67 GTO which is stock. Pulls a ton of air, is quiet, and runs cool. Running a 19.5" clutch fan with a Hayden clutch on my '65 GTO and it runs cool and works fine. Whatever you run, use a 7 blade fan that is at least 18" in diameter to pull enough air through the core.

Running a 7 Blade fan from a 76TA that had was an Auto and had AC. That with a Hayden HD fan clutch has served me well. Along with a 180 stat. Gerry

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
