what intake would u choose to pair with AFR 165 heads for a street car?

can u please explain where the power band is on that head

i am thinking GT-40 intake or the new BBK SSI, can someone please tell me where the bbk intake makes its power?
but please feel free to leave info about other heads

thanks for all your help

Cobra, GT40, BBK, or Edelbrock. The Performer will most likely make the most peak power. The Cobra/GT40 is comparable on top, with a tad more down low. I think the BBK flows comparably with the GT40. I know it supposedly has good lowend oomph. But, I'd go with the Edelbrock. More than likely you're gonna have enough lowend to satisfy you and your tires, but 2nd,3rd,etc. full throttle runs will be better with the Edelbrock.

Well you asked what I would choose so heres my opinion. I would use an rpm II or a holley with a custom cam designed to make power from 3000-6500 and respectible bottom end. But thats me, I like power.

If you were keeping the stock 6250 limiter, i'd use nothing less than an rpm.

Since you own a '94 I would suggest you maintain as much low end as possible because the 94 & 95 weigh a bit more than our 87-93 cars

I assume you are gonna stay with the stock engine displacement (302ci)?

Well with a 302 and 165's, you are probably gonna run a good, but emissions acceptable cam, right? It sounds like a daily driver car to me.

In which event I suggest the GT-40 ... it looks the best (IMO) and you won't lose any low and mid range power ... plus it pulls a lot better up top compared to the factory intake.

You gotta ask yourself why this is the intake that all aftermarket street pieces are compared to ... well, because it is a real good runner and will support up to 400 flywheel horses n/a

Also I imagine you are going to run a 24lb injector? ... in which event there is no need for an intake which will support tons of air flow.

165's are an idle to 5800 rpm head, unless you get them with the upgraded (stiffer) springs to allow the engine to rev higher with matching parts.

Grn92 suggests the RPM intakes, but those intakes favor a bit more top end at the expensive of bit less bottom end power .... plus most of the time street cars are driven in low and mid range anyway ...

I have an RPMII on one of my cars and it works really well, but the car has a 331 (which pulls more air) and is well matched on it's speed parts.

The BBK I have never seen in action, but when tested (in 5.0/SF magazine) on a 302 with 165's it had an erratic power curve ... the writer felt it needed more airflow ... and so when they strapped it on a 347 the erratic curve went away and it did really well making top-end power ... but they still called the GT-40 the best all-around intake of the test for a street car.

If I may paraphrash Ed Curtis "I use a Performer with 165s for street because it outperforms all other similiar design intakes".

I'm using a plain jane GT40E (Explorer) intake on the AFRs. ANYTHING other than stock will make gobs of power with those heads.

Eventually I will bolt a holley systemax on there after the bottom end and rev that bish to 6500...

But for now as mentioned before, an idle-5800 manifold is what we need because we drive the cars on the street.

do u think i should swich to 24# injectors?
do i have to? cuz i have dont have that much money wouldnt i need a new MAF? and if so what size would u think i would need?

if i could i would like to just do the heads and intake and then save up for injectors and the rest of the intake like tb maf filter and stuff like that

Rick 91GT · Jul 27, 2005

Edelbrock Performer would be my first choice....

You dont HAVE to switch to 24s but the chances of your A/F ratio being safe will be slim with ~15 year old injectors. My friend has AFR HCI combo and runs stock pump and stock injectors, he has all kinds of A/F problems though.

I suggest getting a set of 24s with a 73 or 75mm C&L MAF. all that shouldnt be more than $350.

www.jdsperformance.com sells the 73mm MAF and I got my injectors on ebay slightly used but still in great working order.

I would also get a fuel pump, modding cars isnt cheap man but there are some things you cant skimp out on and fuel delivery is one of em...

Good luck.

GT40 or an Edelbrock are my suggestions. As stated before you really want to keep your low end as much as possible and those would be the best choices.

Only one choice in my book. FRPP GT40 Intake

Would retain the most torque where you need it most on the street (down low) by a significant margin (20+ lbs-ft @ wheels) and get you with in 7-10 hp of the best you could hope for on the top end.

Complete, total IMO...........

See this thread http://forums.stangnet.com/showthread.php?t=546405&highlight=intake+shootout Particularly post #11. Average hp AND lbs-ft across the bowerband goes to the GT40. The Performer is behind the GT40 for both hp and torque. That is not better in my book. It's worse.

Also in post #10 I put the peak numbers. The GT40 delivered a lot more torque down low where you need it. Mind you those numbers are on a 342, but the differences in power hold up to a 302 as the same magazine I pulled those numbers from ran those same intake on a 302 and the results were the same withlowe r numbers due to fewer cubic inches.

the GT-40 intake looks like what i am looking for

even tho i like the look of the bbk one, i think i herd that i would need a different hood and i dont know if there is an elbow made for that intake for my 94?

I read most of that in the magazines already

What I like is how someone put up flow numbers in one post and said the Edelbrock had the best average airflow .

My point to that is: It doesn't matter how much air your intake can flow if the car is a dog ... has no throttle response and some guy with a lower flowing intake runs better times at the track too.

Flow is nice to know as a reference, but doesn't determine output or how a vehicle with certain varying components will respond

The Performer or GT40 need lower intake work to flow to the full potential of those hedds - and professionally done, they will not loose any low end.

Some times these magazine tests make me wonder if they are making certain products out to be better than they are. I know that type of stuff takes place, but we really don't know what is true or not. I would listen to what an experienced engine builder or racer like Ed Curtis had to say. He seems to know what works, as he has many wins to his credit. Either intake would be good for a street car. Check my sig for my mods. I am very happy with my combo, (just need gears to put it all together). If you are looking for max power I would get a Performer, and have it ported by a professional like Ed or TMOSS. I know from experience that TMOSS does great work.

Professional means porting them to maintain a constant flow volume throughout the runner ... and runner to runner.

Unprofessional means you gots yourself a Dremel and you gonna make dem holes bigger.

I'd go with the Edelbrock. AFM did a intake shootout. It scored highest for HP and tied for 3rd in TQ. But you couldn't go wrong with a GT-40 either. Get the best for the dollars you can afford to spend.
