RECESSION BUSTER CAMS FOR 2V 3V 4V

All Bullet cams are custom ground and can take 2-4 weeks after order is placed, we do not shelf stock any Bullet cam spec.

If you have us do the cam degree to a set of Bullet cams you will need to budget in 4 weeks total MINIMUM before you see your cams.

Bullet Cams were found inside 7 modular engines that won their class championships, and set 5 modular world records in the 2008 race reason alone.  You may not have heard of them but you see cars using their cams covering over 50% of the fastest modular lists on the forums.  We worked extensively with Bullet to develop these new proprietary profiles which utilize the latest technology for the modular engines.  They are designed and optimized for the unique airflow characteristics of both stock and ported heads.

Please read the detailed explanations below before choosing a cam.  These are not your typical off the shelf one size fits all cam lobe like the other guys.  The lobes are designed for specific duty be it on the intake or exhaust and/or if the application is naturally aspirated, blower, or turbo.  They have very aggressive install centerlines and asymmetrical lobes which make their specs very different than typical cams you are used to seeing.  Duration is important in determining a cam's suitability but just as important is the installation location (centerline) of the lobes.  This is something that many other modular cams have not done properly, and hence you usually don't see it listed in their specs.

If you have any questions about what is best for your combination please contact us.  We have learned what works and what doesn't, and its sometimes different that what is discussed in the forums and magazines. 

We have found (the hard way) that most all other 2V cams on the market have unacceptable intake valve to piston clearance.  Our 2V cams are designed with a minimum of 0.035" of intake to valve clearance for 4.6 engines with PI heads with stock pistons.  While that sounds small it is a safe spec for this engine.  We found 0.000" - 0.005" when we actually measured the other guys cams, and many cases of bent valves. 
 
Don't become a bent valve statistic!
 
All 2V and 4V cam specs are rated with a 1.80 ratio rocker.  The Ford rocker is actually a variable ratio and 1.80 is closer to reality in these lift ranges.  Thus our 0.550" lift spec is a true 0.550" lift in the engine rather than the 0.545" you find from some of the other guys.  These lobe designs are the most aggressive that can be made with the stock Ford rocker system.

Cam bolts
Flat rate shipping of $10 on all orders to lower 48 states!

New OEM or ARP cam bolts for either stock or aftermarket cams.  ALL of the aftermarket cam suppliers have stopped including new bolts with the cams we have found.  Stock cams 99 and newer use 10mm bolts, stock cams 98 and older use 12mm bolts.  All Bullet cams and most aftermarket cams use 12mm bolts.  We give you the options to get whatever you need.

2V Cam gear kit and parts
Flat rate shipping of $10 on all orders to lower 48 states!

OEM Ford cam gears, spacers, washers, and bolts.  You can get either a new kit or a used kit.  I have never seen a worn cam gear myself, and the bolts are good for more than one reuse.  If you have a 99-00 Mustang or any 2V truck you need this kit to install any aftermarket set of cams.

2V Cam Degree Service
Flat rate shipping of $10 on all orders to lower 48 states!

It doesn't matter who ground the cam the advance/retard degree is off spec 90% of the time.  We offer a complete cam degree service for those interested.  Please go to this page for more information.  While it is better to degree on your own engine, it has been found that our service is usually within + or - 1 degree of what you will find on your engine.

 

PI 4.6 NA street strip cam detailed specs

4.6 PI motors with stock pistons has severe intake valve to piston clearance problems.  If using the stock heads only the Torquer, Stage 1, and Stage 2 cams will fit safely.  All larger cams require either modified intake valves and/or piston notches.  These are street and mild strip (less than 7000RPM) cams designed for 4.6 engines with PI heads and all stock pistons.  If you have a PI headswapped NPI engine, this is where to look for your cam.  For larger cams than this please see the next listings.  The exhaust duration is made shorter on PI head NA cams as the exhaust port be it stock or ported is highly overactive compared to the PI intake port.  All of these cams can use the stock valve springs.  We recommend the OEM plastic PI intake, Bullet, P-51, or HPS for these cams.

 

PI 4.6 NA street cam choices
PI 5.4 NA street strip cam detailed specs

These are street and mild strip cams designed for 5.4 engines with PI heads.  All of these cams can use the stock valve springs.  5.4 PI motors have much more freedom with designing a NA cam as the piston to valve clearance is a full 0.1" larger than a stock 4.6 PI motor, so these are slightly different than their 4.6 counterparts.

 

PI 5.4 NA street cam choices
PI 4.6 and 5.4 NA street strip race cam detailed specs

For 4.6 applications all of these cams require intake valve notching of the piston and cams larger than Stage 5 will require exhaust valve notching as well.  Aftermarket springs are required at this point.  Street/strip and race only engines trying to shift no higher than 7000-7500RPM should use the OEM plastic PI intake with these cams.  The best power gains will be found with either the Edelbrock, Logan, or TFS intake with these cams, but the RPM will start getting up there.

 

PI 4.6 and 5.4 NA street strip race cam choices
NPI NA street strip and race cam detailed specs

NPI heads have different needs than PI heads so we offer NPI specific cams.  NPI heads have much more piston to valve clearance than a PI engine, this allows more freedom in camshaft design.  They have more restricted exhaust ports so the exhaust duration is made longer to compensate.  The 525 intake lift cams will work on stock NPI heads, the 550 lift version will need raised retainers on the intake valves or other modification to work.  The Stage 3 and larger require upgraded valve springs.

 

NPI NA street strip and race cam choices
PI - NPI Blower/Nitrous cam detailed specs

Once under heavy boost and/or nitrous the various heads and shortblocks need close to the same cam specification.  The larger big bore, stroker, and 5.4 based engines can use the next size cam bigger than a 4.6 based motor.  If you look closely the exhaust centerline has been advanced considerably to help blowdown the cylinder and release as much heat as possible.  Stage 1 and Stage 2 cams can use the stock springs, all larger cams require upgraded springs.

 

PI - NPI Blower/Nitrous cam choices
PI - NPI Nitrous only cam detailed specs

Stage 1 and Stage 2 Nitrous only cams are designed for the stock plastic PI  intake and up to a 150 shot.  Stage 2.5 and larger Nitrous only cams are designed specifically for the Edelbrock intake and nitrous use up to about a 250-300 shot.  Higher nitrous levels than this usually require more exhaust lobe advance (wider LSA) to blow down the cylinder more at a cost of some NA power.  We can make the LSA wider for no additional cost if desired.  The Edelbrock prefers a very early intake opening point, slightly tighter LSA, has a raised plenum that is not prone to fuel puddle, and allows the use of the popular Holley 4150 sized nitrous plate system when combined with our custom intake elbow.  This is one place to be more conservative than normal when it comes to cam sizing.

 

PI - NPI Nitrous only cam choices
PI - NPI Turbo cam detailed specs

Stage 1 and Stage 2 Turbo cams will work with the stock valve springs up to about 8lbs of boost.  Above that aftermarket springs are required.  Our Stage 2 Turbo cam has made 700RWHP on the stock plastic intake with a single 70mm turbo and 22lbs of boost.  This is one place to be more conservative than normal when it comes to cam sizing.

 

PI - NPI Turbo cam choices
TFS NA cam detailed specs

The TFS 2V heads are slightly different with what is needed for a cam grind. Even though some of the cam specs are the same as the NPI/PI specs these cams are ground specifically for TFS heads.  TFS prefer durations closer to a NPI head and valve lifts closer to a PI head.

46PI TORQUER 215/213 525/500 108/112 110

Will give good low and midrange torque increase.  Good cam for stock torque converter Crown Victoria/Marquis/Town Car, Thunderbird/Cougar, and trucks.

 

46PI STAGE 1       - NATURALLY ASPIRATED 220/218 550/500 110/110 110

Max effort cam for Crown Victoria/Marquis/Town Car, Thunderbird/Cougar, and trucks with the stock torque converter.  Should be used with the PI intake.  Good cam for automatic Mustang with stock rear end gears.

 

46PI STAGE 2       - NATURALLY ASPIRATED
225/223 550/500 110/110 110

Max effort cam for stock PI heads, 5 speed or 3000 stall torque converter recommended.  Crown Victoria/Marquis/Town Car, Thunderbird/Cougar, and trucks should have the torque converter changed.

If you have a PI head swapped vehicle with stock valves still in it, this is the cam for you!

 

46PI STAGE 2P    - NATURALLY ASPIRATED
225/223 550/500 108/108 108

Advanced intake lobe version of the Stage 2 cam.  This is the cam to use if you are willing to remove the cylinder head and replace the intake valve as it will give more midrange torque than the Stage 2 with no loss of top end power.  PTV is very tight with the stock valve and this cam, you only have about 0.005" of clearance with the stock valve and piston with this cam.  With the modified intake valve you are safe.

 

46PI STAGE 2.5    - NATURALLY ASPIRATED
228/226 550/500 110/110 110

This will need modified intake valves to work with the stock pistons.  In comparison to the Stage 2P cam this would be the cam to choose if you are more concerned with 5000-6500 power and are willing to lose some torque below 4000RPM.  This cam should be used with long tube headers.  This is the cam that was used in our 300RWHP 2V combo.

 

46PI STAGE 3R   - NATURALLY ASPIRATED
233/230 550/525 112/110 111

This is a retarded intake centerline version of the Stage 3 NA cam.  Doing this allows this cam duration to be used with a stock piston and modified intake valves with our minimum recommended clearance.  This is the largest NA cam we offer than can be used with a stock piston with the 4.6 PI head.  In comparison to the regular Stage 3 NA this will have reduced midrange torque, however you can fit this one without a piston notch.  Higher flow fuel injectors and long tube headers are recommended.  Mild to rough idle.

PI - NPI Blower/Nitrous cams detailed specs - $599 a set

Here is a FAQ on the 2V cams for the detailed questions

Once under heavy boost and/or nitrous the various heads and shortblocks need close to the same cam specification.  The larger big bore, stroker, and 5.4 based engines can use the next size cam bigger than a 4.6 based motor.  If you look closely the exhaust centerline has been advanced considerably to help blowdown the cylinder and release as much heat as possible.  Stage 1 and Stage 2 cams can use the stock springs, all larger cams require upgraded springs.

Here is a FAQ on the 2V cams for the detailed questions

Stage 1 and Stage 2 Nitrous only cams are designed for the stock plastic PI intake, stock valve springs,  and up to a 150 shot.  Stage 2.5 and larger Nitrous only cams are designed specifically for the Edelbrock intake and nitrous use up to about a 250-300 shot.  Higher nitrous levels than this usually require more exhaust lobe advance (wider LSA) to blow down the cylinder more at a cost of some NA power.  We can make the LSA wider for no additional cost if desired.  The Edelbrock prefers a very early intake opening point, slightly tighter LSA, has a raised plenum that is not prone to fuel puddle, and allows the use of the popular Holley 4150 sized nitrous plate system when combined with our custom intake elbow.  This is one place to be more conservative than normal when it comes to cam sizing.

STAGE 1    - TURBO
217/213 525/500 109/119 114

This cam is designed specifically for 70MM and smaller single turbo systems, and will help with quicker spooling and lower the turbo lag.  It is highly recommended to replace the valve springs with this cam and any turbo system over 6PSI.  This is a good cam to use for a single turbo street car that you want the least amount of lag possible.

 

STAGE 2    - TURBO
222/218 525/500 110/120 115

This cam is designed specifically for 75MM and smaller single turbo systems, and will help with quicker spooling and lower the turbo lag.  It is highly recommended to replace the valve springs with this cam and any turbo system over 6PSI.  With a stock plastic intake the shift point will be around 6500RPM, with the Edelbrock it will be around 7000RPM. 

This is the cam that was used in our default 600RWHP combo.

 

STAGE 2.5 - TURBO 227/223 525/500 110/120 115

This cam is designed specifically for 65MM - 80MM single turbo and dual smaller turbo systems that want higher HP and will trade some lower end lag.  Modified intake valve required for the 4.6 PI.  Aftermarket valve springs required.  This is the cam for 7000-7500RPM shifts.

 

STAGE 3    - TURBO
230/226 525/500 110/120 115

This cam is designed specifically for 75MM and larger single turbo systems, and dual turbo systems.  This is a higher RPM cam and will have more low RPM turbo lag than our Stage 2 and Stage 2.5 TURBO cams.  This cam is intended for use with ported heads, aftermarket intake, and higher 7500+RPM builds.

 


 

TFS specific NA cams - $599 a set

Here is a FAQ on the 2V cams for the detailed questions

The TFS 2V heads are slightly different with what is needed for a cam grind. Even though some of the cam specs are the same as the NPI/PI specs these cams are ground specifically for TFS heads.  TFS prefer durations closer to a NPI head and valve lifts closer to a PI head.  TFS also advance/retard differently than PI heads with the same cams, one head will advance slightly and the other will retard.  You should definitely cam degree all cams for TFS heads.  You can use the stock lighter spec TFS springs up to 7500RPM NA, above that higher seat pressure springs are highly recommended.

The stock cam phaser will allow up to 50 degrees of cam timing retard at cruise for a small gas mileage increase.  This lessens the available cam size you can run in the engine and is the weak spot when higher spring pressures are used.  While they are only recommended with our Stage 1 cams, they are required for all Stage 2 and higher 3V cams.

 

 
SV Series 3V cams are designed to be used with the stock valve springs.
