Product Details

The COMP Cams 7138-10 Keyway Adjustable Billet Timing Set is precision-engineered for Ford small block 289-351W engines from 1965-1988 with crankshafts that have been machined 0.010" undersize. This high-performance timing set features CNC-machined billet steel construction for maximum strength and durability in demanding applications.

Key Features:

  • Keyway adjustable design allows for precise camshaft timing adjustments in 2-degree increments
  • CNC-machined billet steel sprockets for superior strength over stock stamped components
  • Designed specifically for 0.010" undersized crankshafts (reground cranks)
  • Fits Ford small block 289, 302, and 351 Windsor engines (1965-1988)
  • True roller chain construction for reduced friction and improved timing accuracy
  • Includes heat-treated steel components for extended service life

This timing set is ideal for engine builders working with reground crankshafts or performance rebuilds requiring precise valve timing control. The adjustable keyway system enables fine-tuning of camshaft timing to optimize power delivery and engine performance without the need for offset keys or bushings. COMP Cams billet timing sets are a proven upgrade for racers and performance enthusiasts demanding reliability and precision.

The website would not link to PayPal using Firefox browser. So after switching to another browser, I was able to complete the order. The power window switch I ordered arrived 1-day ahead of the advertised delivery date. It works like a champ.

Easy, but wondering about shipping time to my house

Make sure this liner is for a 6 and 1/2 ft bed. Very satisfied with the product,better than expected. Thanks

Only thing that could be done to improve is I would like to know the estimated shipping time

Shipment was quicker than I thought and the product was just as described. It was cheaper than else where. Thank you Autoplicity

Easy, Great Price!
