Camshaft STREET 11.0mm Lift Mild Performance Increased
[SA425]
$395.00 $348.00

STREET PERFORMANCE

This is a great street performance upgrade for all Weber and Spica cars. Our #425 11mm cams are similar to the factory European 1750/2000 performance profile with the same  good lowend torque, better midrange and a lot more top end.  Duration 245 degrees @ .050" lift.

  1. A pair of these 425 Cams is a smooth step up from the stock cams, and brings the engine power a pleasant boost by raising the torque curve mostly on the low end.
  2. ALTERNATIVE SETUP:
  • Substitute our 11.0mm #425 cam on the exhaust side.  For street performance with emplasis on low end performance.  Mid-range will be about the same with both. 

FEATURES:

  • Bolt in with no clearance issues with any piston. 
  • Use our basic VSS12 performance valve springs
  • Our cams have super durable lobes that are first hardwelded before precisioon regrinding.
  • To minimize lobe interference with follower bores with high lift performance cams, the base circle is undercut to 1.030."
  • We strongly recommend upgrading to VSS12-1 springs for 11.6 and 12mm lift cams.

All new and reground cams should be installed with new followers.  There is risk of damage with old followers. Unfortunately, there are inferior quality followers on the market and we can only guarantee satisfaction with Spruell Motorsport followers. 

CAMSHAFT EXCHANGE CORES REQUIRED

Sorry, but we are no longer able to fill customer camshaft orders without exchange cams in hand.  Even after we upped the core charge from $50 to $75, very few cam cores were returned  -- NO EXCEPTIONS.  ADD $65 FOR SET OF FOUR FOLLOWERS.
