NEW ROUSH YATES BELT-DRIVE TIMING GEAR FOR FORD WINDSOR-BASED ENGINES

Written by Moore Good Ink


belt drive assemblyMooresville, NC: It’s no secret that most popular pushrod-engine racing technology, regardless of venue, is rightly born of the rigors of NASCAR racing. Timing gear is no exception. In the late eighties, the dry-running, cog-belt-driven system rose from timing chain failures that frequented NASCAR racers during 500-mile contests.

Ostensibly developed for the Roush Yates 358 cubic inch (NASCAR, ARCA, Craftsman Truck Series) and 436 cubic inch (WSORR and TORC off-road series) engines, its new cog-belt system is a precise link between camshaft and crankshaft, tough enough to endure 24-hour races such as Daytona and Le Mans or a full-season of circle track competition. Further, the system enhances any engine based on the Ford Windsor cylinder block.

Years of service are assured simply by replacing the belt at recommended intervals (before every race, yearly, or as abuse dictates). Besides producing less friction and being more durable than gear- or chain-drives, the Roush Yates system offers race and high-performance street engines a number of advantages:

1. Adds external accessibility and adjustability of the timing gear itself, which can be advanced or retarded (up to 25 degrees overall) during dyno testing and tuning. No need to remove the front cover of the engine or drain the coolant system

2. Eliminates harmful harmonics to guard against valve train instability

3. Provides billet aluminum upper pulley for additional strength and features cogged-tooth configuration

4. Supplies heat-treated steel cogged-tooth crankshaft pulley for strength and reliability

5. Accommodates both dry-sump and wet-sump oiling systems

6. Features upper vent ports for cooler-running belt assembly

7. Furnishes all Grade 8-spec fasteners for strength and protection against most metallurgical failures that affect fasteners

  1. Will the Roush Yates timing belt system be long-lived for street and highway use? Hope to increase fuel mileage in my Ford F250 1973 360 Fe engine. It’s due for a ring and valve job soon. Any wisdom is appreciated as every little thing helps.

    • From Todd English of Roush Yates: Good morning Curtis – this belt design is suited for racing applications and may not meet the challenges of everyday driving. I am also not sure if it would even fit your FE engine. Nonetheless, thank you for your kind inquiry.
