oddly obsessed with big scoops on little Mustangs

65 coupe,351w,C4,Big Boss 429 hood scoop,8" 3.40 TracLoc.

My guess is the D1ZZ9424G is the equivalent of our Boss 351 intake
with whatever carb pattern the Aussie XY Falcon GT came with. We had
Holley pattern intakes and Motorcraft 4300D spreadbore patterns.
The Performer 4V intake is practically the same height and carb cant
angle as the stock Ford dual plane but I wouldn't call it an improvement
over the Boss 351 intake. If anything, the Performer is a step backward
with smaller ports than the 4V heads. Here are the A and B measurements
(in inches) of some 351C intakes I've measured:
A B
Edelbrock F-351 & Performer 2V/4V.......3 1/2.....4 3/8
Weiand Xcelerator 2V....................4 3/16....5 1/8
Holley Strip Dominator..................4 5/16....5 3/8
Blue Thunder............................4 7/16....5 3/8
Ford aluminum 4V........................3 1/4.....4 3/8
Offenhauser 360 4V......................3 1/2.....4 1/2
Weiand tunnel Ram.......................9 1/16....9 3/8
Weiand tunnel ram base only.............6 1/4.....6 1/4
Weiand tunnel ram top only..............2 3/4.....3 1/8
Motorsport A351 (Roush).................6 3/4.....6 3/4
A331 (Edelbrock version, not Roush).....4 3/8.....5 5/16

Your best bet for a step up would be the Blue Thunder dual plane
high rise which is based upon the old Holman Moody part but it's
an inch taller than a stock Ford intake.

I've got a Holley carb pattern Boss 351C intake here. If you could
find me a Willpower single plane intake for the aluminum Rover V8,
I might want to do a swap..

There's a DIZX-9425-FA on ebay at the moment, but its not listed in the Dan Jones tech article... nearest number and description is the "Ford 351C 4V intake (p/n D1ZX-9424-FA)
- high rise single plane aluminum intake with Dominator flange
- available over the counter"
I imagine its taller, but the piccy doesn't look it?
ANyway... a willpower single plane for a rover V8? I'll ask around... we got a 4.4 litre version of the Rover down here in the Leyland P76 so theres bound to be some interesting bits around...

Not that loser again :-)

Yup. Are you after the spread bore version or the Holley version.
The spread bore fits only the 4300D Motorcraft carb and will not
mount a Thermoquad or a Quadrajet (different bolt patterns and
bore spacing).

That was an over-the-counter single plane intake. I think Ford ran one
on the Pantera they ran at LeMans but the intake doesn't seem to have
been used much. The circle track guys used the Bud Moore mini and
maxi plenums and the street guys ran the Holman and Moody dual plane.
The DIZX-9425-FA intake looks a lot like a Weiand Xcelerator 4V.
I've got pictures of most Cleveland intakes if you need to see something
specific.

> I imagine its taller, but the piccy doesn't look it?

It's not as tall as a Strip Dominator but I've never measured one.

Willpower makes similar intakes for the Rover and Leyland P76.
I need the Rover version. The Leyland P76 has a taller deck.
The specific version I'm interested in has injector bungs cast
into the runners. It's still a 4 barrel carb intake but the
bungs can be drilled for injectors or nitrous nozzles.

Yes indeed.
