Ford Small Block Application Info

Short Waterpump

Short waterpump (SFM) pulley systems are a good choice for applications where there is a minimum amount of room between the engine and radiator. This combination is 1-1/2 inches shorter than the long waterpump kit. Requires the use of a reverse rotation 94-95 mustang waterpump and timing cover and electric fuel pump.

Waterpump/Timing Cover Kit:  Ford Racing #M-8501-A50 (1994-95 Mustang)

 


Long Waterpump

Long waterpump (SFL) pulley systems are the same length as factory Ford standard rotation systems and will fit most applications. Must change to a reverse rotation waterpump, but most 1970 & up timing covers will work. Works with electric or mechanical fuel pump.

Waterpump:  Ford Racing #M-8501-C50 or equivalent (1986-93 Mustang)

Timing Cover:  Ford Racing #M-6059-D351 or 1970 & up equivalent

 


Which Waterpump and Timing Cover Do I Have?

Use these pictures to identify which waterpump and timing cover you have. As always, there are exceptions to this illustration. Particularly, some late model Long Waterpump timing covers may have the fuel pump boss either blocked off or not there at all. Don't hesitate to call us if you have a question.

Block Accessory Hole

Most 1970 and newer blocks have an accessory hole on the passenger side of the front face of the block. Most older blocks do not have this hole. Our standard kits have a bracket that bolts to this hole, but we have an alternate bracket that bolts to the ground strap hole for blocks where this hole is not present. There is no difference in price, we just need to know if this hole is present or not.

Boss blocks including the new Ford Racing Boss block have an unmachined boss and no drilled and tapped hole. To make matters worse, the ground strap hole has been moved on this block so our alternate bracket will not fit. The best solution for Boss blocks is to grind the unmachined surface as flat as possible and drill and tap the hole for our standard bracket.


Additional Notes

  • Kits are designed for use with electric cooling fans. If you need to run a mechanical fan, we can make modifications to the waterpump pulley. Also, if you use a mechanical fan, remember that this kit uses a reverse rotation waterpump, so make sure the fan is a reverse rotation fan.
  • When using Concept ONE kits in older Fords with the radiator inlet on the passenger side, lower radiator serpentine conversion hoses are available for some applications or custom hoses such as Cool-Flex® can be used to reroute the radiator hose.
  • Ford 90° thermostat housings are recommended
  • Typical rack & pinion units used in the aftermarket are the Mustang 2 (less common) and the Fox Body Mustang / Thunderbird racks (more common).  Mustang 2 racks generally need to run in the 800-900 psi pressure range.  Fox Body Mustang / Thunderbird racks (NAPA part number often used - 22-203F) generally run in the 1100-1200 psi range
