Description

Add some spunk to your motor with a TWS Motors cam kit. If you're still running an OEM cam, it is likely worn and robbing you of power.

Our cam kits are all specifically ground to suit your needs and application based on the selection you make during checkout. If we do not have something we think fits the needs of your car, we will have one specially ground, at no extra cost. 

  • We only use high grade camshafts, made from the best materials. Sourced form the USA and UK.
  • Comes with the Cloyes double roller timing chain
  • Cam will be faced based on vehicle and engine size
  • Our lifters are made in the USA and are made to the highest quality in the industry. Don't be fooled by cheap imitations.
  • Camshaft upgrades are worth 10-20hp and 10-20tq depending on other modifications

How to Guide (Lifter Prep, Preload Settings, Cam break-in Procedure) PLEASE READ:

Cam break in procedure (Summary):

  • Be sure to soak lifters in mineral oil. See link above for more details.
  • Be sure to setup lifter preload correctly. See link above for more details.
  • Fill engine with break-in oil. We use Driven racing oil break in 10w40 or Royal Purple break in oil, which can be found at your local auto parts store.
  • Break in motor for 20 minutes at 2000rpms. DO NOT IDLE MOTOR DURING THIS TIME.
  • If you purchased a 14CUX chip, please stock chip and MAF for break in. Change out to TWS chip and MAF after break in.
  • Change oil after break in process. We recommend 20-50w or 10w40 with zinc or zinc additive. Valvoline VR1 20-50 for hot climates or Driven Racing 10-40 for warm climates. NO SYNTHETIC OILS
  • Check oil after first 500 miles. (checking for oil level, fuel smell in oil, shininess in oil (metal))
  • Change oil after first 1000 miles.
  • For 14CUX, GEMS or Bosch vehicles, we recommend you follow the initial break in procedure, followed by a quick 5-minute drive, shut off the car and let sit for 15 minutes, followed by a 15-minute drive. This will allow the ECUs to adjust appropriately.

If you are building a race motor or forced induction motor, heavy duty valves springs will be required. Please call +1-508-880-5448 and press option 2 to discuss the details or email contact@twsmotors.com 

Fits:

  • All Triumph TR8s
  • All Defenders up to 1996
  • All Range Rover Classics
  • Any distributor equipped Rover V8
Warranty
Due to the many things that can go wrong in the start up process we do not warranty any camshaft that is not put in/broken in by TWS. Please follow the break-in procedure listed in the listing.

    Performance Cam Kit

    Posted by Martin Glennie on 16th Mar 2025

    Really good guys to deal with. Thoroughly worked through my requirements and very detailed to provide the best possible cam profile.

    Better than I expected.

    I am very pleased with the performance of this camshaft kit. Since it was my first time with this type of engine upgrade I was unsure. However, Woody was very descriptive and explanatory. I can really tell the difference in the lower and mid range torque. My Range Rover is more responsive and seems like it has more power available at cruising speed. Thanks a lot for making this a pleasant experience. Douglas

    Nice cam

    Posted by Darrell Walker on 22nd Oct 2013

    Took Woody's recommendation for the best grind for my car (basically stock 3.5 FI engine with headers, daily driver). Cam arrived quickly, installed easily, and is running great. Not sure how much is due to removing the old, worn cam vs. the new spec, but very happy with the improvement. Engine pulls strong @ 2K in 5th, old cam required a downshift, and where there didn't ever seem to be a point in going over 3.5K with the old cam, it now blows through to 5K, with some grunt left.
