Hello all, I took a look on this site and found willpower and wildcat intake manifolds, but wasnt able to find where to get them. Does anybody have a webpage or phone #. Or know where to look for a used single plane carby manifold for the early rover V8. I was told by a friend of mine that torque power might make those????? I looked on their site and found nothing. Waiting for e-mail back from them. Any help would be greatly appreciated. Sincerely, David 67wickens@sbcglobal.net 213 792-6270
David,
The manifold you mention was originally made by Huffaker and was effectively copied by Harcourt in Australia and as far as I know they are only available from Wildcat and JE Developments in the UK. but you could try Faxing Harcourt to see if they still actually make them.
Be interested to hear of another source as they are not cheap at £360.00 but obviously cast in small numbers.

ask for Bill Laney... Remember they are 17 hours ahead of you.. so if you call from LA at 7pm it will be noon the next day where he is at..... you will need to do an International wire transfer from your bank into his....
Tony,
Maxwedge are apparently the manufacturer of the Willpower intake and a web search came up with a price of $650.00 AUS so not much difference in price although oyu exchange rate might be more helpful.
Of the three manifolds, Wildcat, Harcourt or Willpower I don't think there is a lot of difference as they are all based on the original Huffaker as far as I can find out.
Kevin.
Keep an eye out in Australia. I got mine from Triumph Rover Spares in Adelaide:
http://www.triumphroverspares.com.au/
They just so happened to have one laying around. I got it for $150 but it took $100 to get it to the USA. In hindsight though it was worth it. I stayed up late at night to call them after emailing a couple times. I just saw a pic of it in their part specials section. They could come across them now and again though. Mine had been modified for a spread bore carb. It's a Hardcourt BTW.
Good luck man! Also peep the AU ebay...

I don't believe that is the case. I have both a Willpower and a
Huffaker here. They are different intakes and performed differently
in my flow bench testing. The Huffaker has Buick 300 sized ports
and requires an external thermostat. The Willpower has ports
slightly larger than a Rover/Buick 215 and has an integral thermostat.
The Willpower can also be ordered with injector bungs. The Willpower
is apparently the same as the Wildcat intake, though.
Here's a previous post I made after testing the Huffaker and Willpower
intakes:
After the heads were ported, I spent a little time evaluating a couple of
Rover V8 single plane intake manifolds on Dave McLain's flow bench in Cuba,
Missouri. I wanted to know which of the intakes would flow best when bolted
to the ported 1964 Buick 300 aluminum heads. The two intakes tested were a
Huffaker:

http://www.bacomatic.org/gallery2/v/hidden/dan/dan-cars/album10/album13/Huffaker_bottom_side.jpg.html
and a Willpower:

http://www.bacomatic.org/gallery2/v/hidden/dan/dan-cars/album10/album13/Willpower_2.jpg.html
Note the Willpower intake pictured is not the actual intake tested. I've
not yet taken pitures of the intake we tested but it differs from the one
pictured in that it has EFI injectors bungs in each port but the injectors
were not installed for these tests. The Huffaker has larger ports which
better match the Buick 300 heads:
http://www.bacomatic.org/gallery2/v/hidden/dan/dan-cars/album10/album12/Buick_300_Huffaker_ports.jpg.html
The Willpower has smaller Rover-sized ports but has a better radius on
the end runners than the Huffaker. An end port and a center port of the
head were first flowed without an intake attached to get a baseline, then
flowed with the intake bolted in place. Also, a Holley 780 carb body
with the throttle plates at full open was bolted to the intake to
represent the pressure drop across a carb or fuel injection throttle body.
I'll be using an EFI throttle body later but have not purchased it yet.
When the heads were ported, they were tested on a Superflow bench at a
28" H2O pressure drop. The head had a clayed intake radius but no exhaust
pipe stub was used on the exhaust. Those numbers are shown in the 2nd and
3rd columns. The 4th and 5th columns are the same head flowed on Dave's
bench which has a 10" H2O pressure drop. The numbers were converted
mathematically to 28" to be on a consistent basis. Note the numbers are
somewhat lower than those of the 28" bench. We're not sure if this due
in part to the conversion or is simply bench-to-bench variation. In any
case, it doesn't influence the results of the intake manifold tests.
On both single plane intakes, the center runners are short and straight
while the end runners are long and curved, so one center port and one end
port were tested. The Huffaker was bolted to the head and tested first,
followed by the Willpower. The results are shown below and are best
viewed in a non-proportional font like courier:

Despite the smaller runners, the Willpower is the better flowing manifold.
The center ports on both intakes are quite close to the head flow but
the Huffaker end ports are not as good. I think it would be worthwhile to
port just the ends of the Huffaker intake end runners with a better radius
to see if the flow loss could be recovered. There's a slight drop off in
flow as lift increases on the Willpower intake that may be due to the small
port size. The Willpower could be ported to a larger size but given how
close the intake is to the bare head flow, it's probably not worth the
trouble. The worst flows are at 96%. As a point of comparison, we've
recently flow tested a couple of (non-Rover) dual plane intake manifolds
and they were in the mid seventy % flow range (unported).
The exhaust-to-intake flow ratio on these heads is excellent. Dave thought
a bit larger itake valve, at the expense of exhaust valve size, might make
more power if it were practical. During our tests, a 4" diameter tube was
used to simulate the effects of the cylinder wall. To see if shrouding
might be a problem, the tube was moved around (closer to the valve) but
little effect was noted.

Maxwedge is the manufacturer of the Willpower intake as well as the Wildcat version for the stock rover heads...
The Harcourt and Huffaker are both different manifolds as well and neither are being manufactured anymore.

Want to insert a table into your message? I set up this message board to allow some HTML tricks.
Here's a big hint what the proper syntax for a table would look like...
With a little cutting, pasting, and some very minor editing, this:
Quote<table border="3">
<tr> <td></td> <td>column 1</td> <td>column 2</td> <td>column 3</td> </tr>
<tr> <td>row1</td> <td>A</td> <td>B</td> <td>C</td> </tr>
<tr> <td>row2</td> <td>D</td> <td>E</td> <td>F</td> </tr>
<tr> <td>row3</td> <td>G</td> <td>H</td> <td>I</td> </tr>
</table>
...will create a table that look like this:
<table border="3">
<tr><td> </td><td>column 1</td><td>column 2</td><td>column 3</td></tr>
<tr><td>row 1</td><td>A</td><td>B</td><td>C</td></tr>
<tr><td>row 2</td><td>D</td><td>E</td><td>F</td></tr>

</table>
Other HTML commands can be used to change alignment of data within the table cells, etc.
does anybody know max-wedge performance e-mail address??? Also curious,, These manifolds(Willpower etc) do fit the 215 and the 300 or is there a difference??? Thanks, David
The willpower manifolds do fit the 215.. and a 215 block with 1964 Buick 30 heads..
it will not fit a Buick 300 without adapter plates... They are too wide.
You can try to contact Bill ...williaml@hotkey.net.au
Wow, Almost exciting, got my "Wildcat" 4bbl. manifold today."No charge" for machining debree" left in manifold. I figure because they were soo rushed to fill my order...over 4 months. All 24, "top hat liners" also arrived. Problem there is,all must be bored aleast 3.75" to clean-up. Best I can hope for is a, "very warm place will freeze over", before I re-order. Anyone want a new , manifold they don't have to wait 4+ months for? I'm beginning to see why we declared independence so long ago.LOL.-almost. roverman.
Art,
Was the manifold direct from Wildcat, does not sound like the sort of service you would expect from Ian Richardson?
kevin.
Art, You got 24 liners? I like the 3.75" bore though, even if you have to do it. It makes a true 300 then!... Ok I've got issues.
Can you post a pic of the Wildcat intake?
Greg
Got my Willpower intake from maxwedge performance in Australia in just a couple weeks... Good casting. no machine shavings..
(http://www.usfamily.net/web/hoffbug/Willpower%201.jpg)
Water neck not included..
Kevin, Yes Ian. Not the type of service I was expecting. Nic, you've got issues? I've got 24 "oversize" liners and I'm not even a super-senior! Pic for manifold-not easy-I'm ninethumbs. Looks just like manifolds posted in forum, except for 'debris and age-spots". Has thermostat cross-over but no injector bungs. I will install sleeves with, "Loctite Sleeve Retainer"-anerobic. Most of my blocks are "pink", so , bore-out old sleeves and definately visual and sonic test. Block filler on"killer"motor. Happy HP. roverman.
Tony, Thanks for the contact info. Dave
Roverman, Did u say u r selling the manifold?? Dave
Bill Laney [Max Wedge] in Sydney OZ makes Willpower manifolds which is same manifold sold in U.K. by Ian Ricardson under his company name of Wildcat. Bill Laney also makes a V- shaped cast adaptor similar to factory BGTV8 but better flowing, to take 2 S.U carbs; manifold can come with cast lugs on inlets to be drilled out for injectors;and adaptor plate is available for putting on a blower. There is also wider version of Willpower manifold to go on Aussie Leyland P76 4.4. v8 , saves adding spacer plates to Rover or Hardcourt manifolds, not sure if this will fit Buick 300.[ i have a Huffaker on my BGTV8 and Willpower on my Leyland P76 4.4 v8.]
Steve.. I had forgotten about the P76 intake!... I wonder if it would be a direct swap onto a Buick 300?
I found these pictures on the web. from a site in the Netherlands....http://www.roversd1.nl/sd1web/index.html

left to right: 3 Intakes, P76, Buick 300, Buick 215
Hard to tell but from the pictures the P76 manifold it looks just a little wider than the Buick 300 manifold?
Anyone know for sure?
It would be a little wider. The P76 has about a 17mm taller deck (~.675") and the 300 has about a 9/16" taller deck. (exact figures are available if you do a search) The 340 is ~1-3/16" taller.
Jim
The wider Willpower manifold for a P76V8 could be machined by a good engineering shop, i'll ask Bill Laney and report back.
I got a response from Bill myself..
Hi Tony
P76 manifold valley width is 8 ¼"
Buick valley is 7 ½"
Rover V8 valley is 7"
I can make the Rover manifold wider by casting extra metal on manifold flange to suit Buick 300.
This means there will be no spacer plate required.
Valley plate will be cast and added to seal valley to block.
It will be purpose built to suit Buick 300 motor.
I will e-mail pic when I cast in approx. 4 weeks.
Regards
Bill
That was quick. You know, once he does the 300 intake it's a very small step from there to the 340 intake. Nobody makes one of those at all, and it shouldn't be hard to make it suitable for use with the new TA heads. Think of that, a light weight 340/350 cu.in. motor with performance alloy heads and a single plane intake that is a straight swap for the 300. I know they will be getting several sets of those new heads in Australia within the next few months. Tony, would you care to suggest that to him? There is an active Buick performance group who would probably jump right on that, in fact I have heard some of the 350 guys say they would build a 340 if they could get an intake.
Jim
JIm.. I think the manifold port sizes would work OK on a 300.. the problem with just widening that manifold is that the port sizing would probably be too small for a 340... Even the Iron 300 heads are larger than the Aluminum 300 heads.. The problem with this type of custom stuff is that the average enthusiast just wants to buy a bolt on item from a T/A or a Poston... and at Small block Chevy pricing to boot..
Its too bad a Poston or T/A couldnt buy a dozen or so in either size ( Buick /Rover 215 and Buick 300) From Bill and offer them up on a trial basis... Only these guys would know if there is enough of a market to justify casting up a larger port manifold..
The distance across the valley on the 340 is 8-13/16", so a 1/4" spacer per side should come pretty close to making the P76 intake fit... if there's a 4bbl one available. That'd take care of the 340 with alloy 300 heads, but as you mentioned, the TA heads have larger ports.
Jim
Yes, the P76 manifold is wider than the Buick 300 manifold. I know for sure.
Greg
To recap,Bill Laney- MAXWEDGE is still making Rover v8 single plane manifolds , as well as for P76, and now also making new single plane manifolds for Buick 300 this month. to contact Bill ,email [williaml@hotkey.net.au]. I'm lucky as only live few minutes from Bill and can pop around to see his latest manifold.
Steve, why don't you ask him what it would take for him to do one to match the TA-Performance heads to the 340? Ian at Triumph-Rover Spares will be getting two or three of the first four sets of those heads (by year's end - they are now being machined) and several guys stateside have expressed an interest in a 340 based build-up if they had an intake. I'd be happy to pass the information along to them.

Size is OK.... but.....
P76_340_2.JPG
Port size is not so OK... It would work fine with 64 Buick 300 heads. Not so much with the later ones or the TA heads...
Greg
Bill Laney ''Maxwedge'' told me he will look at TA performance heads to make a new manifold if and when he can get a hold of a set.At moment manifold for Buick 300 is been made, contact Bill on williaml@hotkey.net.au.
Thanks Steve, I'll pas the word along.
