- Price: By way of explanation, there are two separate castings that are used to make the different versions of the intake adapter, the medium riser casting and the high riser casting. The high riser casting is heavier and more expensive.
The standard medium riser adapters use the medium riser casting; the price for any of these adapters
(part numbers
13000 through 13099) is
$569.00.
The high riser casting is used for the later Blue Thunder medium riser heads, and also for all the high riser variants; price for any of these
adapters (part numbers
13100 through 13199) is
$689.00. If you are purchasing the #13101 high riser manifold that allows the use of a 351C
intake manifold, you will also require the #
13201 port plates; these are machined together with the intake adapter to make the 351C intake
fit. Price of the port plates is
$125.00, in addition to the price of the intake adapter, for a total cost of
$814.00. If you just want one of the high
riser castings to use as a base for a sheet metal intake, the port plates are not required.
Pricing for the
tunnel port version of the adapter is
$779.00; the tunnel port version starts with the high riser casting, and
is more expensive than the high riser version because of the added cost of adding the tubes in the tunnel port adapters. Also, the
tunnel port adapters are only available with straight-through ports; after looking at trying to make a 351C intake work with the TP port
location, it just doesn't look practical without a major bend in the ports. So the tunnel port adapter would be useful for building a sheet
metal intake manifold, or possibly for adapting a Pontiac Ram Air V intake to the FE tunnel port engine.
All these intake adapters include the machined manifold casting, the large machined access cover plate, the smaller machined road draft tube cover plate, O-rings to fit both of these removable plates, the water bypass nipple, and 6 allen head bolts required to install the intake adapter.
- Terms: Payment can be made via Paypal, Visa or Mastercard, money order, or personal checks drawn on US banks. If you send a personal check we will hold the intake adapter for 7 business days prior to shipment. We ship to US destinations via UPS, and international destinations via the US Postal Service. If you are outside the US, you are responsible for any duties and taxes due when the intake adapter enters your country.
- Delivery: The intake adapters will be shipped within 3 days of receiving payment via Paypal or money order, and within 7 days of receiving payment via personal check. Shipping charges are figured individually for shipment via UPS in the United States, and via USPS for international destinations.
- Returns or Refunds: We will do our best to ensure the quality of these parts, and work with anyone who is not satisfied or unhappy with this purchase to attempt to rectify the situation. However, because of the small percentage of people who abuse return and refund policies,
FE Power LLC sells these parts AS IS, with no warranty regarding fit and finish, and no returns or refunds available.
- Options: There are several part numbers of the intake adapters available; see the description and photos below.
Part #13001 adapts the standard 351C 4V intake to the FE.
Part #13002 has the FE ports coming straight out (rather than curving in to fit the 351C intake), so that a custom intake manifold like a sheet metal intake can be made starting with this intake adapter.
Part #13003 has a starter hole only machined in each port location, for anyone who wants to do their own porting work on the manifolds.
Part #13004 is the same as #13003, except that there are no machined port openings in this adapter.
Part #13006 is for a Yates style 351C intake, like the Edelbrock 2991 or 2863.
Part #13101 is the standard part for high riser intakes. Please note that in order to make a 351C intake manifold work with the high
riser adapters, a 3/4" spacer plate is required (described below).
Part #13103 is for the later Blue Thunder Medium Riser cylinder heads and a standard 351C 4V intake.
Part #13180 is the standard part for the tunnel port intakes.
For part numbers 13002 through 13004 above FE Power also has available, for $125.00, a pair of 1/2" thick aluminum flanges that bolt to the manifold, and can be used as the starting point for a sheet metal intake. These flanges seal to the intake adapter with O-rings that are included with the plates.
For the intake adapters designed for use on high riser heads, such as part #13101, a 3/4" spacer plate is available for $125.00/pair that will allow a 351C 4V intake manifold such as an Edelbrock Torker or a Weiand tunnel ram to bolt onto the intake adapter. These spacer plates are also available with no ports machined, for use as the starting point for a sheet metal intake. The plates seal to the intake adapter with O-rings that are included with the plates.
For the intake adapters designed for use on the tunnel port heads (part #13180), 3/4" spacer plates are also available for $125.00/pair, for use as a starting point for a sheet metal intake. These spacer plates have the round tunnel port ports that match up to the intake adapter already machined, and seal to the intake adapter with O-rings.
IMPORTANT - Every 351C intake that we have looked at requires some modification in order to be used with the intake adapter. The front rail of the 351C intake needs to be cut away so that it doesn't interfere with the water jacket on the intake adapter. This can be done with a hacksaw and/or a die grinder, or you can ship your manifold to FE Power and we will machine it to fit. We charge $85 per manifold for this service. Currently we have programs in place for the 351C Performer RPM, the Edelbrock Torker, and the Weiand tunnel ram. If you have a different manifold that you want to use, we will be happy to develop the programs to modify it but this will add some time to the process. Needless to say, modifying a 351C intake manifold to work with this intake adapter will make the manifold unusable on a 351C engine.
Also, the Yates style manifolds must have their flange surfaces machined thinner in order to work with the #13006 intake adapter. Again we offer this service for $85.00.
Finally, if you have any special options that you would like for your intake adapter, such as a change in pushrod hole size or location, or no pushrod holes at all, we will be happy to try to accommodate your request; email us to discuss.
Please feel free to email us with any questions on these adapters, or post them here if you prefer. You can contact us via email at jayb@fepower.net
The photos below show the #13001 intake adapter. The adapter shown in these photos has not yet had the thermostat housing holes or water pump bypass tube hole drilled and tapped, and also does not show the center cover plate and road draft tube cover plate:
The photo below shows the 13003 intake, which is delivered with machined starter port openings:
The photos below show the 13002 intake, which is delivered with FE sized ports coming straight out of the adapter. The second photo shows the manifold from the side, so you can see the port configuration. The third photo shows the 13002 intake with the port plates installed. These plates are available as an extra cost ($125.00) option for this adapter, as a starting point for a sheet metal intake. The fourth photo shows the plates themselves; on the side of the plate that bolts to the adapter, there are O-rings to seal the ports, so that no gasket is required. The O-ring grooves are spaced farther away from the inboard side and top of each port, to allow plenty of room for porting.
The photos below show the 13004 intake adapter. This adapter is delivered with no port openings whatsoever; it is basically a blank canvas for port work.
The photos below show the 13103 intake adapter. This adapter starts with the high riser casting, and is designed to work with the later style Blue Thunder medium riser heads. These heads have larger port openings than a standard medium riser head, with the roof of the port raised and the port widened. The high riser casting is used to make this intake adapter, because the standard medium riser casting does not have enough room above the Blue Thunder ports for a good seal to the intake gasket. Also, due to the width of the port in the Blue Thunder head, the intake pushrod holes are moved towards the center of the engine by 0.250" on these adapters. Note that for these adapters some porting work in the roof and the floor of the port will be required for best flow.
