FED no longer offers dyno or Spintron testing to the public.

The intercooler within our Iceman Intake Manifold is rated up to 2,000 Horsepower.

You can only use GM style LS7 rockers, or custom Jesel and T&D shaft rockers.

Any intake that was designed to fit the stock platform with work with the F-series.

This all depends on your combo and how well it’s built. It could be 50-150 hp.

There are several options depending on your build. Make sure to explain your goals and combo to your salesman so they can properly guide you to the correct components.

Yes, we offer titanium intake and exhaust valves and we offer an Inconel exhaust upgrade.

Yes, we offer mold star 90 or CHE copper upgrades.

This is block dependent and you will need to consult the stud manufacturer of your choosing.

These heads are designed to use a LS7 style header due to the bolt hole locations. We also recommend a header of 2” primaries to work best.

Standard Tapered Seat spark plugs.

You must check pushrod length with a checker on every set of heads with your desired lifter to insure proper pushrod length.

Torque your heads to the correct torque specs of the head bolts or studs your using.

Use Wallaceracing.com and use their compression calculator online.

35-60 rwhp

The seat angles depend on the head and the application. This is also proprietary information.

This completely depends on if there in good condition. Only upon inspection can this be determined.

This will depend on the material the valve has to work with. If there is enough margin to work with then there’s a good chance we can adjust the angle correctly.

Depending on the thickness the deck starts at it could be up to .150 but in most cases .050.

We recommend Cometic or Felpro for all your gasket needs.

This will be discussed with your salesmen to determine the right combo.

This is a conical cut in the combustion chamber that has a certain angle applied from the edge of the bore to the center of the cylinder. This prevents fuel from being trapped in the quench area and slows the burn to allow for a wider tuning window and serves to prevent detonation.

Yes, we can angle mill your heads, but this will also require the head bolt hole to be corrected and the intake flange to be corrected.

We sure do, we do a lot of high-end custom work for very specific classes with very particular rules.

We recommend a minimum of .080 intake and .120 exhaust but if you’re a professional engine builder you can run them to your desired comfort level.

This will depend on the combo, RPM, and cam. Please ask your sales associate.

Our Billet intakes can hold 75-100 PSI.

Depends on the combination and gains will vary.

Yes, they are but they’ll need fitting to adapt them correctly.

You will not need gaskets with our intakes, they use rubber O-rings to seal.

Depending on the intake some are built for 90mm and some for 102 or bigger.

Yes, we do!

Usually, we can unless the manifold has been modified previously.

This all depends on the application. Talk to your salesman for more information.

This depends on the spring kit. Most of our hydraulic kits are good to .680lift and our solid roller standard kits work to .900 lift. We can also spec custom kits to meet any needs necessary.

We spec custom cams for most of our builds, or you can call Steven at Cammotion for advice.

We sell lots of custom cams to suit all your needs.

Lash can be checked hot or cold and the numbers will vary. You need to check what the lash recommendation is for your cam. Then you’ll check lash when the cam is on the base circle, you’ll check the Intake lash when the Exhaust valve is just opening in the cycle. Then you’ll check the exhaust lash when the Intake valve is closing.

This is a question for your tuner, engine builder, etc.

LLSR stands for Low Lash Solid Roller. This just means the lash required to use this setup is very minimum and allows for minimum valvetrain adjustment.

We build prototypes and then we test them on the engine dyno. After we get the results we’re seeking we’ll give the products to other shops to do real-world track testing. We also use CFD software to help us design the best product possible.

We use MAZAK, HURCO, CENTROID, NEWEN, and Rottler.

Some of our products are available on our website or you can also call us directly. We have a lot of dealers around the world that you can also use the find a dealer on our webpage.
