Norris Performance Camshaft, Grind #407S - Type 1 Engines

Norris has been making performance VW cams since the early 60's, and are pioneers since the very early days of VW racing.  To this day, they make some of the very best cams around, matching them to almost any VW engine configuration. We're proud to carry a full selection of these cams in stock, and can special order even more for specific racing applications.  From bone stock, to all out drag racing, we have a Norris cam that matches your exact needs.

All Norris cams are manufactured from the highest quality proferal billets, and will work with 40HP engines, single port 1600 or dual port 1600 based builds.  All Norris cams require the early "flat" style cam gear.  Each cam comes with the three correct bolts to secure it to the gear.  We have several different cam gears available as an option that match these cams well  The USA-made aluminum cam gears work fine on most any application, except engines that are equipped with dual valve springs and revved higher than 6000 RPM's.  For the more mild applications, EMPI cam gears will work fine, too.  If you want the utmost in performance, steel straight-cut cam gears work excellent on any engine and any RPM range.  Since they are straight cut, they will eliminate the thrust load on the cam bearings, freeing up some power and minimizing wear.  Straight-cuts do make a very distinctive "whine" sound, which some people really like, and others don't.

Norris no longer makes lifters, we recommend using quality Scat lifters, as these have proven to match these cams very well.  We have two different lifters that we use to match them.  The standard lifters work great for most any application.  The lightweight 75-gram lifters also come with an oiling hole in the center that lubricated the camshaft.  For racing applications, using a lightweight valve train and this extra oiling will help keep things working well together, particularly at higher RPM's.

Lobe centers are all ground at 107 degrees for maximum power in the low RPM range, all the way up to whichever power band you choose the cam to match.

#407S - THE "MID-PERFORMANCE STREET & OFF ROAD"  CAM - This cam is another favorite of many "Old School" builders.  This cam is designed to be used with 1.1:1 stock ratio rockers, but can also be used with 1.25:1 rockers for even more lift.  We recommend solid shaft improvements on the rockers, as well as HD single springs.  If revving past 5500 is desired, we recommend dual springs and/or shimming the HD single springs to match. Chromoly pushrods are a good idea, as well.  This is a high lift, fast ramp cam, which makes gets the valve up quick, and keeps it there longer.  This creates big power and a great power band.  Idle will be a little lumpier than stock, so we recommend setting idle at a minimum of 1000 RPM's.  Works best with big valved heads, and even better with ported ones. Displacements of 1776cc or larger are recommended.  Works fantastic with 1835cc or 1914cc with the right components, and even better with 1904cc or 2054cc.  This is still considered a "mid-performance" cam, having smooth driving characteristics.  Great to beat the rice-burners at the drag strip, run in your off road car, or beat your buddy to the next light.  Buckle up and prepare for sprited driving.
