The typical CFM requirement for a big block vehicle like your 454 truck for a fan is 3,500 to 4,500 lbs.

The part # D16934 can pull 4,000 CFM so it would fall within the range required. This is the highest rated electric fan system we offer so it would be the best option we have. As long as the dimensions of it match the available room you have and the radiator this would be a great option.

This fan setup measures 31-3/8" Wide x 15-3/4" tall x 3-1/4" deep. Since you have 3-1/2 inches between fan and AC pulley this setup would give you 1/4 inch of clearance...
