N45 | Hi Capacity Fan |
N65 | Torque Drive Fan |
N51 | Maximum Cooling |
That's interesting but makes sense. Not just slightly wider but slightly more pitch as well. My friends super bee 383 auto with a/c came with the 216 fan. we thought because of the a/c was the reason for the slightly wider fan. It came equipped with 3.23 open rear .Thanks. Learned something new.Here's what I found in my manual for a 1970 340 4spd Dart............
Fan 2863 215.......18 x 2 1/4 pitch torque drive clutch (no thermal spring)
Fan 2863 216.......18 1/2 x 2 1/2 pitch torque drive clutch, if equipped with 3.55, 3.91, or 4.10 rear axle ratios.
That's all I've got.
