Holy smokes! My son was describing this to me  a week or two ago. The carbon fiber one seems to be of most interest. Who makes these??

I found them on speedway motors in the hot rod section...pricey but its fun to imagine. I was looking for shorties.

Hmmm..... The silver scoop sitting on dual carbs, although pricey, comes as a kit (all inclusive). The info  associated with kit says the carbs come with manual chokes. The installation instructions (PDF), however, indicate that the scoop can be used with carbs w/ electric chokes (which we're most interested in). But, unfortunately, they seem to only be selling the kit with the manual choke setup. I didn't see another vendor selling this kit.  Am guessing a kit with dual carbs with electric chokes would be well beyond our price tolerance.

 

I'm thinking that the fake carbon fiber example sitting on just a single carb (with electric choke) of our choice might be our best bet to keep costs in check.

 

Thoughts?

I post up weird ideas all the time, ask anyone...lol!
I think its a cool idea but its expensive and other than looks I don't know that the cost is worth the gain (if any) in HP and I'm not sure if a tunnel RAM is good for HP or torque? Marty may know being a hot rudder...?

Definitely a cool idea in the looks dept. Here are two from Summit that might fit the bill for less. I'm sure ebay would have something even cheaper......

 

Will await the word on functionality from our hot rod guru.

Did you guys happen to see this? Announced at SEMA on Monday.

http://www.atomicefi.com/

supposed to be a super-easy EFI upgrade for carbed engines (didn't see anything in the thread that made me think you were looking, just thought it looked like an interesting option for an SBC)

Take a look here too - http://www.alsblowers.com/sc510.html

And here - http://www.up22.com/scoopw2.htm

I wouldnt count on the scoop really adding any power over a traditional round air cleaner assy.  If you want power make sure to use a good filter and maybe a style that helps to straighten the airflow, like on my Camaro below.

I wouldn't use a tunnel ram manifold, that's all for high rpm HP gains.  Depending on the stats of your SBC I'd use either a dual plane or an "air gap" style single plane manifold.

My experience for EFI on old school motors is to stay with a carb.  The 427SBC above is a monster with a carb.

I've had fuel injection on - 383SBC, 502BBC, 638BBC and all of them were eventually removed and replaced a carb.  This included systems from GM, Edlebrock and F.A.S.T.

Plus if you have any sort of cam, in my experiences, the EFI takes out a lot of the lumpy idle and the top end.

Now on a new school LS6 motor I had - EFI was wonderful!

Hmmm...has anybody seen any cost estimates for the Atomic EFI?  Wonder what they're going for?

 

I think a forward facing scoop in the back, sitting up between the seats, would look pretty neat, but if it negatively impacts HP - not so interested. I'm curious as to whether a scoop adds any protection to the filter from the elements (rain)?

The scoop wouldn't really hurt your HP, I'm just saying don't expect huge HP gains thinking there will be some huge ram air effect.

What intake manifold are you planning, or have you even gotten that far?  What are the specs of your SBC - 350? 355? other?  CR? Cam? Heads?

350, 30 over Flat tops, Vortec heads (already modded for dual springs and increased valve lift) Crane cam (numbers at home... mild) GMPP fast burn manifold.

Be careful when selecting the headers for those heads as they have a D shaped port.  Ever try to put a square peg (or d shaped) into a round hole? 

My buddy's 383 has the vortec heads and no one checked the header style when making the selection.  He's is very frustrated because to correct will require everything new from engine to x-pipe, all custom too.  Just sayin

I'd also run the carb GM recommends, period.  We are on the 3rd system on my buddy's vortec 383 and it's still not right. (1st - fuel inj; 2nd - quick fuel carb; 3rd - holley carb).

since you are talking about headers. don/t buy any that have less than 3/8" flange plates or you will have leakage issues.
