Product Description

Beehive Spring Kit for FE Ford

Max Output II Beehive Spring Kit

Fitment: FE Ford w/ 3/8" Diameter Valve Stems.

Here is the long awaited Max Output II Beehive Spring kit for FE Ford with Hyd Flat Tappets.

With their 1.70/1.72 ratio rockers, FE engines can produce a lot of lift, even with mild cam profiles.

We custom tailored this kit to work with hyd flat tappet cams in FE Ford engines.

Good up to .650", these beehives fit right onto the stepped spring base Ford used on so many FE engines.

This is a big deal because no other supplier has put the effort into creating beehive kits for FE Fords.

Proud to say, these are an Alex's Parts exclusive- made up to our specifications. We looked at the various beehive springs currently available from all the cam companies and non of them were suitable for this application so we went ahead and had PAC produce them for us.

        Questions & Answers:

  • Q- How important is it to measure valve spring installed heights?
  • A- Setting up installed heights is important for the following reasons:
  1. Measuring installed heights will assure the intended seat and open loads are achieved.
  2. Builders who want maximum performance will always measure their installed heights and add shims as needed to get the installed heights as close as possible to the target spec card included.

 

  • Q- Will this kit work with 11/32" stem valves?
  • A- Negative, this kit is indented for FE Ford running valves w/ 3/8" stems. (Stock stem diameter)

 

  • Q- How close do I need to get the installed heights to the target height spec?
  • A- As close as you can with a tolerance of minus .015" to target height. In order to improve installed height accuracy and if it's possible, it's wise to set it up around .005" on the low side of the target height. Once the engine is run, 10 degree retainers/locks will seat further into the retainer. This is a natural process, retainers and locks will seat and as this happens, the installed height will increase a very small amount so it's better to lean on the lower side of target height.

 

  • Q- Will I need an installed height micrometer to set up the installed heights?
  • A- Yes, in order to properly set up installed heights, a height micrometer suited for beehive springs will be required. It must also be capable to clearing Ford's stepped spring base. The mic must contact the same surface as the spring.

 

  • Q- We have a beehive installed height mic which we used on another application- will it work on my FE heads?
  • A- That depends on the brand and model of the mic. Some height mics are designed for beehive springs and LS Chevy heads or for aftermarket heads with a large flat spring base. Mics for such applications will not clear the raised "step" on FE Ford heads.

 

  • Q- How can I determine if the beehive mic we have will work on an FE Ford?
  • A- Just measure the opening (bore) on the bottom of the mic. If the inside diameter measures 1.025" or larger, it should work.

 

  • Q- Can I measure the installed heights with a machinist scale, snap gauges or calipers?
  • A- Negative, this is not a viable option for the following reasons.
    Calipers, snap gauges or a machinist scale will only work when the measurement is taken parallel to the valve stem and not at an angle. Since the heads stepped spring base is bigger than the retainer, these tools are not useful for this application.

 

  • Q- My existing installed height micrometer has a stepped top surface which the beehive retainer enters into and contacts the bottom of the step below. The readings I'm getting are .150"+ more than my target installed height. Whats going on and how do I deal with this?
  • A- This condition happens when an installed height mic designed for larger diameter retainers is used with a beehive set up. On common "cylindrical spring" installed height mic's, the shape of the top of the mic is intended to clear the first step used on bigger retainers. Most beehive retainers are too small for Std installed height mic's and will fall into the counter bore which produces an inaccurate measurement.

 

  • Q- How do I determine if the top side of my mic will work with a these beehive retainers?
  • A- Just measure the inside diameter of the topside of the mic and compare it to the OD of the retainer. The retainer must sit on the top surface of the mic and not inside its counterbore.

 

  • Q- Do I need hardened shims?
  • A- Yes. Std shims are too soft and will break down during use. Std shims should not be used because as they wear down, fine metal particulate will contaminate the crankcase oil.
