Hi, Anyone know where I can get NEW pulleys for the 400m. After 35 years of use mine need to be replaced. I am having a hard time finding stock pulleys since support for these engines are limited. I know there are aluminum pulley kits for this engine but I want to stay away from them since they are over price and will wear out faster. Do any other ford engines share the same pulleys as the 351/400. I know that the 302/289 has good parts support so would I be able to piece together different pulleys from other engines. I am in need of a Crank pulley, P/S pulley, W/P pulley, and Alternator pulley.

Thanks

 

Do you have factory A/C. Is the alternator single or double belts, does your truck have (or had) an air injection pump?
And last but not least, what truck do you have, year, model, 2/4 WD? Truck serial number (last 6 digits of the VIN)
The reason I need to know all this stuff is:
There are 5 different crank pulleys, 3 water pump pulleys, 2 alternator pulleys, and 5 power steering pulleys. If your truck is 4WD I need the s/n to look up the right power steering pulley.

 

No factory A/C, just the under dash heater, alternator has single belt. Not sure if it ever had an air injection pump. The truck is a 78 F250 4WD.

Whenever there is a numeric 0 or an alpha O in the part number prefix, its often entered into inventory incorrectly so I search both ways. Thats why there are a couple of pulleys that I list with the two different, but same, numbers.
Also, on the pulleys that I listed with an engineering number, that number should be stamped on the pulley. If you see a different number let me know what it is and I can cross it to the correct p/n.

 

Some great info there Mike.
seems like a thank you is in order from the OP
