shaker vs aar hood on big hp engine

[AUSAAR]

Gday everyone.
ive heard the shaker hoods can be a restricion for high hp engines. but i cant find anywhere what point they start to bring the power down. my current build should produce somewhere around 500fwhp but id like to go for a stroker with roller cam one day so id like to build everything to take 700hp. height might be an isssue for me but i will have to get my engine into the bay and do some measurements before i know that. has anyone ever tested the airflow through a shaker bubble. with no hot/cold doors and no grilles. has anyone opened up the holes in the shaker? and does the aar hood have any limits.
thanks in advance.

This may not be a direct answer to you question but - Although SHAKERS do have lots in the WOW factor dept. They can be a PITA if you got lots to do under the hood. Trust BIGS on this one!

My friend had an SS/D hemi Cuda he was looking for every single hp he coul dfind , he tuned the engine on a dyno with O2 & found about 40 hp  until he put the shaker back on , then it went right back to where he had it tuned , the AAR would be my choice

have the shaker for looks, but under the hood have a ramairbox, with snorkels going to front of engine. You'll be ramming cold
air for max power.

I have seen a barracuda w a "shaker" where the bubble was bolted under the hood for looks. And sort of a back yard ram air box. I'm sure he runs cooler under hood temps than I do.

I also would go with the AAR hood as you will probably want a tall intake for max HP.  I struggled with keeping my stock hood with my 500HP stroker and although I would probably make more HP with a taller intake, i did not want to lose my dual snorkle stock hood.  The AAR hood would give you more room . . .

sounds like aar is the way to go. running a tunnel ram but converted to efi so i should be able to loose a fair bit of height there

You can remove the brackets under the dual snorkel hood, that are above the carb, for more room. Not sure
how much it will weaken hood. I did it, and seemed to be no problem.

Are you racing?

I would go w/what looks better and your preference.  You won't lose HP until you get up past 4000 RPM.  How often are you up there?

Also, what year 'Cuda you got?  I'm not a fan of AAR hoods on 1971+ cars.  Nor am I of Shakers on '72+ cars.  My $0.02.
