Which maxwedge intake for 500cui stroker?

[spocksbrain]

Hi guys,

i’ve a 72 Barracuda and my goal is a 500cui stroker (base 440 rb) with 500rwhp, in the moment equipped with the 727, means I’d need around 630hp on the dyno. The car should be built for street and will see the strip only a few times.

I decide to take away the 906heads/rpm-intake/770 holley and want to go for maxwedge with
the EZ1-cnc’d/???/850or 950carb.

I’ve two issues:

• I’m looking for a nicely working mw intake. When looking through some moparmusclemagazin articles I assuming that a dual plane intake would be fine for my goal, because don’t will high rev all the time, where the single plane intakes usually have advantages

1.Edelbrock Performer rpm
The Intake:
Edelbrock #7193
Type:
Aluminum Two-Plane Four-Barrel
Rated rpm Range:
1,500-6,500
Max hp:
610.2@6,100 rpm
Max Torque:
590.2@4,000 rpm
Avg. hp 4,000-6,600 rpm:
555.9 hp
Avg. Tq 4,000-6,600 rpm:
:555.4 lb-ft

2.Holley street dominator
Pls note: mmm figured out after the test that this intake has been modified
And is not “out of the box” like the rpm intake
The Intake:
Holley 300-14
Type:
Aluminum Single-Plane Four-Barrel
Rated rpm Range:
Idle-4,800 rpm
Max hp:
636.0@6,200 rpm
Max Torque:
598.2@5,000 rpm
Avg. hp 4,000-6,600 rpm:
572.5 hp
Avg. Tq 4,000-6,600 rpm:
571.1 lb-ft

3 INDY RB

no data

4. MP P4876337 single plane, but if someone recommends this one also to work fine in lower rpm-ranges… why not?

no data

If you'd see another intake should be the way to go... pls let me know!:happy7:

• hood clearance (if needed will go for drop-base, 2” air-filter). Right now the rallye-hood is installed, and the new combo should fit in there. But I’ve also an eye on the shaker-hood. Would that bring some 1/10 of an “ ?

Would be great if you could give me some ideas about these topics…!

I think the only dual plane intake with the larger Max Wedge ports is the Indy dual plane .
The Holley Street Dom is an awesome intake for street use & could be ported to increase size closer to Max W

@Chryco

yes, you are right!.
It will go eigther way ICH 440-2D or 337.
They were compared a while ago and the single 337 behaved on a 572 even a little better than the indy.

I think 630HP is going to be tough to make this engine streetable.

single-plane intakes don't give you a lot of lower-end torque numbers and those big-port heads also won't contribute well in the lower RPM register.

So I wouldn't go with max-wedge ports.

I think if you get serious roller cam (but not too radical), Performer RPM intake, 850 vac. sec. carb, ported Super Stealths or EZs (non-maxwedge) heads and get compression close to 11:1, you should be getting close to 600hp and be streetable.

Hi ragtopdodge,

you are right, driveability is a good point.
I'll do some reseach on yor advices and the combo you suggested is cool.
I found a video on you tube and got in touch with the guy to ask how he did his project, because i think throttle-response is awesome

I think that a max wedge intake conflicts with your wanting a dual plane for low and mid range power. Max wedge was tuned to peak at 6500 RPM.

I have driven a 500+" 440 with Indy Max wedge port heads & Intake , it is very drivable & responsive given the extra CI
