I have a 454 with vintage a/c, 27" x 18" x 2" core radiator (brass). i have a crappy flex fan with no shrowd. gets hot in stop and go traffic. switching to an electric pulling fan. what cfm is neccasary? is there a such thing as too much cfm. is a 16" with a "claimed" 3900+ cfm enough? help??

coldknock 's right put a shroud on it. You can still buy original fan shrouds or Summitt has universal ones. Get you a new fan with a clutch for A/C applications and ride.
