WOW!

440 4-spd:

??

***** 4bbl & 6bbl w/3.55s & non-A/C (A36) =
2998956 26" radiator + 2863216 7-bade 18-1/2" dia. fan + 2806070 torque drive clutch fan + 2998326 fan shroud (the big $$ same as max cooling/HEMI parts)

***** 4bbl & 6bbl w/4.10s (A32) =

Some Superbirds are an exception to the above numbers, during production of the Superbirds they changed from the 216/070 to fixed fans on some engine/trans combos to aid airflow/cooling due to the small grill opening.

I would like some more 70 B body 440 4 speed owners to chime in on this topic. My 70 GTX 440 4 speed with A33 axle package does not have the torque drive fan listed on the build sheet. It has N51 maximum cooling noted but does not have N65 Torque drive fan on the sheet. I am under the impression that all 70 440 4 speed cars came with a fixed cooling fan versus the fan clutch. I look forward to hearing more on this topic.

I stand corrected ......216 fan and 070 clutch it is. Here is a snap shot of the codes on my 70 GTX 440 4 speed with A33 axle:
