Stock Cobra intake

02 281 GT · Feb 23, 2010

I'm having an AFR 185 headed, 11:1 c/r 347 built this summer, and I was wondering if I would be seriously restricting my power up top if I stuck with the stock intake. Even if I had it port matched to the heads?

I would think the best thing to do would be what I did on the other stang. I had the cobra lower and upper fully ported and polished with the upper being cut open runners ported and welded together again.

There are better intakes out there, but the Cobra intake is a decent piece. Depends on what you are looking for.

I believe it's Tmoss who ports intakes for us Stang nuts. As I remember, it's the Cobra lower that is the restriction, not the upper. So port matching the lower to the heads would be your best bet.

I have a stock Cobra intake on my 331 stroker with AFR heads and all the goodies. My tuner said the engine could def have better HP/TQ numbers but the intake is holding it back- acts like sucking air through a straw.

I'm happy with it, it is more for show anyway.

I think it is too small

Port matched would not flow as much as a full on port job

Even fully ported ... I have to think it would choke a 347

I agree, but if you are willing to sacrifice 15-20hp to keep the stock intake, it will work. You really can't port the cobra intake too much.

I'd mainly just like to stick with the stock intake because I like the stock look. That, and it would probably be cheaper just to port match the lower to the AFRs. If I don't stick with it I'll probably be going with the Edelbrock Performer RPM II.

The answer is definitely yes. You'd have a 210cfm intake on 260cfm heads so you'd be losing a fair chunk of power. Even porting the Cobra won't be enough so I suggest you go for an aftermarket intake.

Hi
It pricey but you could have it extruded honed it is pricey but if you like the stock look it would help a lot.

Just another option.. I'd like to see a comparison ... some dyno numbers before and after. Maybe next year
