Hurricane EFI manifold too big?
I've got a 355 with an RPM Airgap and carb right now with Vortecs. I'm converting it to EFI and planning to build a 383 in the future. I already bought some AFR 195s that I'm going to put on the 355 for the time being, so I need a new intake anyway and might as well do it all in one shot for the 355 and worry about the 383 later.
The Hurricane EFI manifold looks huge. Am I going to lose torque vs the dual plane carb setup at this displacement? Same question goes for the Edelbrock Victor E and Accel manifolds I've been looking at...but they don't look as massive as the Hurricane.

Re: Hurricane EFI manifold too big?
Cam in the current 355 is a Comp 280H flat tappet (230/230 .480/.480 110). I am going with a new roller on the 383 build...and a tighter LSA does sound really nice. haha
So there should be no issues with a speed density tune either?

Woody! I'm here on recon too! I have been reading that the single plane disadvantages go right out the window with EFI. There is a sticky above that has good info on the single plane intakes.

Re: Hurricane EFI manifold too big?
I have run mine on 2 setups, both 400" motors in my turbo car but part throttle driving it acts like any other.
One setup was mild, just a 195cc head and 233 cam. Very torquey. Drove great despite low comp and 2.73 gears! No real loss of power that i could feel with the single plane. Felt no diff than the hsr on my high comp 383.
Current setup is huge 245cc heads and big 246 deg cam. Figured id see a lazy bottom with this heads cam setup. Nope. Feels even stronger than before.
Single plane willl give broad curve like hsr since runners are somewhat similar in length.

I'm running that exact intake because my Holley wouldn't cover the 1206 ports of the AFR 210 heads.
The intake looks huge due to the air gap design. It's 6" tall, and the runners are a little longer than a miniram.
The Victor is actually smaller, shorter runner, which technically would mean it would be for higher up in the powerband.
Single vs dual doesn't matter on a DRY application like port EFI, since your not relying on a vac signal to the carb. However runner length does matter for effective powerband.

Re: Hurricane EFI manifold too big?
Well, yeah...huge as in the runners look massive. And I know huge runners on heads mean less torque. Maybe EFI is the cure?

Re: Hurricane EFI manifold too big?
I haven't noticed any torque loss with the single plane. In my opinion, it's right there with the MiniRam although the runners are slightly longer with the single plane and therefore build better midrange. Another benefit is the air distribution. Very easy to tune and a very stable idle. This was not the case with the MiniRam. Hood clearance is not a problem even using a 1" carb spacer, 1/2" air cleaner spacer and Spectre cold air kit.
BTW - I bent the crank in my 406 and am pulling the motor and selling the intake if interested.

Re: Hurricane EFI manifold too big?
they have 2 size of the Hurricane intakes
the Hurricane, and the super Hurricane (for 420cid and up small blocks)
im going to swap my accel proram out for one of the super Hurricane intakes (can even get it polished) for less then the accel.

Re: Hurricane EFI manifold too big?
I don't think the regular hurricane comes in an EFI ready version. Both "Coast Performance" and "KMJ" usually have good prices on these. The one I used on My cousins car was polished, and I noticed that the prices for the polished version can vary by well over 100.00.
The airgap under the plenum is quite big and you should be able to hide most of your wiring under the plenum.

Re: Hurricane EFI manifold too big?
yes the super Hurricane is all set up for EFI. you get there rail set, for like $229, it has all the lines fittings and even a EFI reg. (i heve mine) but even from summit all this set up runs polished for just under/at $560.
JUST THE ACCEL PRORAM with rails ran $505 when i paid for it..
just want to ask pp ON monday a few things..

The super hurricane and procomp is the same casting. The manifold pictured above is actually the procomp, which retails for $168.

Re: Hurricane EFI manifold too big?
Seems like a good bang for the buck. My non polished victor was a touch over 300 bucks but it can be ported to 1207 easily. My cam guy doesnt seem to like the victor single planes but they do seem to work from the cars i have seen run them.

What throttle body is this? It looks like you almost could have gotten away without the carb spacer.

Re: Hurricane EFI manifold too big?
ya know i like the polished look..so i can look past its made in China Stamp! but at the same time the ports have to be cleaned up to even fit a felpro Gasket...(saw one today)
and my US made intake, Looks like it was made by felpro...for the fit and finnish of the ports...
but i do like the looks!
1. no vac ports..Not a 1.
2. needs port clean up to work with felpro gaskets (if you care)
3. big made in China stamp on bottom (cant see it when on car)
4. ?

The radius of the corners is not the same as the felpro 1206, but neither is my AFR 210 heads. If you hot it out to perfectly match the 1206, now you have to grind your heads too..

Mine fit a felpro 1206 almost perfectly... The only thing I cleaned up was a little casting flash inside the runner.

The smallest AFR heads i use are the 220's.and they fit the 1206 with out having to do anything. the intake i have now needs almost nothing, just a touch if anything. no casting to clean up
all that work was done be the Maker...helps out alot
below is what the felpro 1206 gasket fits like..intake gasket can move down maby 3mm.at time of install.. needs no work to speek of.
below.what mine looks like at this time (world prodcs. Motown /accel ProRam) SUMMIT $505.95..PRICE DROPPED TO $489.95 I seen. only 1 Vac port..the uper plenum. fits my elbow. almost 1 to 1.
might just Pick one of the polished intakes up. at $200 Thats cheap...to do a side by side. and pick the one i like..and send the other one, i dont like, back..

Re: Hurricane EFI manifold too big?
How is the port match from the AFR 195s to the Hurricane EFI intake? I have heard that head ports bigger than the intake are acceptable, but intake ports bigger than the head ports are a big no no.

Re: Hurricane EFI manifold too big?
yes the US Motown intake will take no work, just bolt it on. if you want to use 1206 felpro gaskets.
all the runners have no casting flash/crud
nice and smooth.But for over $400 what would you expect..lol
has for the Chinese intake the ports look to be Diff Sizes also..or is it Just me.
yes that could be fixed also.(less work then Polishing!!)lol
below is what the felpro 1206 gasket looks like on my AFR 220 Eliminator Heads
100% CNC worked.
the gaskets are a bit small top and bottom. It's a simple fix. and i think the 1207 gasket might be a bit Big. (ill grab a set and see)
this is has close, in the out of the box bolt together, that Iv seen. for the ricky race intakes and heads..Now just add 15lbs of intercooled boost! and the big sticky Tires, and you could have a OK street car!

Re: Hurricane EFI manifold too big?
Funny you mention that. I got the 195s used and they are supposedly comp ports, but a call to AFR said there is no way to be sure by decoding them. I guess I'll have to grab a gasket and see.

Nope. Not Eliminators. 91038 195 HV is what is on the head face. What would be the intake valve diameter if they are comp ports?

Re: Hurricane EFI manifold too big?
What did you pay for them ?
The 195 eliminators outflow the old 195s with comp ports, and the 195 elims with comp ports flow like a 210 head. If I recall, I think the old 195s peak at like 260cfm.

Re: Hurricane EFI manifold too big?
Those are the old odd 195s. If I recall, they had fitment issues with some manifolds because the port is raised. I know early HSR's didn't cover the port, and I suspect the older holley singleplanes would have the same issue.

I probably paid too much at $900. I assumed they were Eliminators because the engine I bought them off had less than 1k on it. However, I'm the third owner of the heads. The port issue has me a little worried too, because these have already been surfaced and I cc'd them at 60cc.
Can you figure out how tall the ports are from the bolt centerline?
What do they actually measure for h x w ?

Re: Hurricane EFI manifold too big?
You might have paid too much. I sell Elims in for around $1350.. But if they work they are still better than most off the sheld alum heads in that size, so maybe it wasn't such a bad deal.

Re: Hurricane EFI manifold too big?
Yeah, I know they are not Eliminators. They have an A on the side and not an AFR.
anesthes, any thoughts on the port measurements?
I like the clean look of the Hurricane manifold with no logo and the tall runners, but if it will be too much for these heads I'll go with an Accel setup I found used for a good price.

The "hurricane" manifold sold on ebay is 99.9% sure to be a procomp casting, and will say so on the front. (see image). They are same manifold, made in the same plant, some go to procomp, some go to pro products.

Re: Hurricane EFI manifold too big?
How about the port sizes on the Accel or Motown EFI intakes? I've been searching used setups and I found one of each for good deals. The Accel comes with the DFI computer & harness and the Motown comes with no electronics or wiring. But for either one I can wire them up with standard OBD1 stuff.
