What's in the Box

Speedway's Street King Ford C4  transmissions are completely remanufactured with heavy duty clutches, special shift kit, and 12" torque converter. Street King C4 transmissions are rated to 550 hp, so they'll work great behind your high-output 289, 302, or 351W small block.

  • Handles up to 550 HP
  • 2200-2400 rpm stall 12" torque converter
  • Firm, crisp shifts from Kevlar bands and H.D. clutches

  • Billet 6061 T6 Aluminum Pro Shift Servo - extends clutch and band life
  • Improved Lubrication Circuits - reduced heat/prolonged life
  • Chrome steel transmission pan
  • Requires a 164-tooth flexplate (not included). Transmission has a one year warranty.

The C4 transmission number 57426101 will not bolt up to the flathead V8’s but Speedway offers a kit number 91028906 that includes everything needed to mate the two including the transmission. We also offer the same conversion with an AOD transmission number 91028907.

Unless your 1987 302 has been balanced different from factory specs it requires the 50 oz. weighted flexplate such as number 57518320-50.

These are designed and fit the small block Ford V8 engines including the 289, 302, and 351 Windsor. They will work behind other engines that accept the C4 bellhousing pattern. Compare your engine to the optional transmissions available for that application. You may want to contact Street King to see if one is offered for your 2.3.

The transmission does come complete with bell housing. Torque converter is listed as 2200-2400 stall and 10 ¾” bolt pattern. It requires the 164 tooth flex plate and also the block plate number 91029012 for proper torque converter alignment. For other specific questions please call and speak to a tech

B&M 70265 Super Cooler Polished Aluminum Transmission Oil Cooler
(Part #20070265)
                        

The last thing you need in the middle of a race or a road trip is to have a transmission or engine go south because your oil cooler can't keep up. B&M's SuperCooler oil coolers will keep your transmission or engine cool and running in your time of need. They're made of lightweight aluminum, with an efficient "stacked plate" design. Multiple cooling paths give them the cooling capacity of larger fan-and-tube coolers. And, because they have a low pressure-drop design, there is less oiling-system restriction.

100% brazed construction provides superior strength and minimum overall size. Stacked fin and plate design is 33% more efficient than the same size tube-and-fin cooler.

Measures 4-1/2" x 11" x 1-1/2" thick with female 1/2 NPT ports.  Cooler efficiency rating of 7,500 BTU.
