theres no way you could go wrong with an rpm II and stroker. that gets my vote.

[TheBocSez]

Save yourself some cash and get the Typhoon.

[95 GTS]

RPM II or a Holley systemax II

When are you going to get heads and cam ?

[Lifted78Chevy]

thanks 4 the info, ....just sooo many diffrent intake manifolds out there hard to get the right one......have read good stuff on the eldebrock intake so might go that way.....thanks 4 yalls input

[Lifted78Chevy]

ok going with the trick flow rated between 1500-6500 for 511 bucks.....this open up my stroker a lil bit over the stock crap i hope.

If I were buying a manifold for your combo , I would get the RPM II or find a really nice ported Cobra intake for it (I'm talking something big) . You could also get a Typhoon and have it ported to your heads on the engine as well .

[Aerocoupe]

Stock Cobra upper and ported lower. I don't think you don't really have the heads or cam for a Holley Systemax II or Edelbrock Performer RPM II. Do a search on this over on the Corral and you will find several guys running a 347 storker with the Cobra intake. I had one and it was great up to about 5500 rpm. My new combo was too much cam and head for it so I moved up to the RPM II. You can use the RPM II with your combo but you will loose bottom end torque. TMoss is probably the most qualified on the Corral to answer this question so do a search with TMoss and Cobra intake. Should get you a bunch of reading. Another thing to consider is reving a hydraulilc roller cam over 6000 rpm. This is starting to get into the area of a solid roller cam. I know there are people out there doing it but some have had problems as well. Just something else to think about and research. Talk to the cam builders as they will let you know what intake matches your current head cam combo but don't get mad if they say to change heads or cam.

ok sounds good......i just want to get better flow because my stocker is crap.....i don't take the motor over 5500rpm so i want a good intake that flows great up to 5500 rpm...heads do need up graded...has a b cam which ain't great but better than stock.

[thesource]

Another option is to have a stock intake ported by Thumper racing . It would flow good numbers and still appear stock . Personally I'd pick up a used Typhoon and spend the cash getting it ported . I know a guy that could do a really nice job on it for you .

[Lifted78Chevy]

well u know what they say don't spend the cash on polishing a turd its still gonna be a turd.....so no cleaning up the stock junk.

If I were you I would be looking for a cam heads and intake. The heads are going to be a big restriction. Good used heads and intakes are comonly availible. The B303 is not the greatest cam, but it will work and will work a lot better if you get some better heads and intake.If you stick with the B303 I would get a set of 1.7 racio rockers. As for heads the Twisted wedge heads are a good choice for the money and can be stepped up to work with about any combo you build in the future. The high ports and canfields will do the same. There are many other heads out there that will work. Since you have a 347 the increase in cubic inches will have many advantages, such as it will be much easier to make compression. So heads like the Dart Sr. will work well with their large chambers and ports. If you only had a 306 the big darts are not a good choice because they will lower your compression too much for a natrally asperated combination unless you buy some dome pistons. You should have gotten better heads and intake before going for more cubes. Since you have the 347 short block I would start looking for a good set of heads. As for buying a set of 351 or other stock heads. I would skip that idea I have found that by the time you get a set of larger valves,replace the guides,possible seats,screw instuds,machine the spring seats and a resurface. You have spent more than many of the aftermarket heads cost and the head you have will not flow what the aftermarket head will. Also many people install or try to install 2.02 or larger valves in stock heads, this is a waste of time and money, the heads will not flow enough to make use of a valve larger than a 1.94 and anything larger than a 1.94 will be shrouded by the combution chamber and will reduce air flow. I would not go larger than a 1.84 valve in stock head personaly. Then you get into needing to port the head that will make the head cost as some CNC ported aftemarket heads such as a AFR. I bought the Twisted Wedge heads on my car years ago, they were used, I only paid $600 for them. There is a company in China that is making copies of some of the Edlebrock heads. I think it may be the same company that makes the Typhoon intake, it is also a copy of an Edlebrock intake. I have seen these heads for sale in the $600 range new in the box. I think there are two versions, one is a copy of the Victor Jr the other is a copy of the Peformer or possibly the Peformer RPM. You can regularly find TW heads and GT40 Y and X heads and sometimes Peformer heads for less than $800 used. As for the intake for a milder engine possibly the Typhoon. The Cobra/GT40 are possibly the best intakes to use if you do not plan to go over 5500, they will make more power than most up to 5200. I you want more RPM and power the Performer RPM II is a very good choice. The TFS street heat is a good intake but the RPM II is better. The TFS Track Heat is a good intake if you plan on using a large set of heads and healthy cam and the Holley Systemax is the intake to use if you make a lot of power, but I would not use it unless you are making in the 400 hp or more or you are going to boost the engine. I you want a good combo that will make lots of power be streetable and have a strong low and mid range I would get a set of TW heads and the Performer RPM II and a Crower 15512 or 15513 cam with a 75mm TB and a 80mm MAF and some 36 lbs injectors and possibly a set of 1.7 rockers. Then when you have the money have someone that knows TW heads very well do some mild work on them they will need a little chamber work and some mild port work then they will out flow most of the more expensive heads.

Typhoon Intake...Pics - Corral Forums

Offer him $225.00 shipped and spend another $150-175 to get it fully ported (upper and lower) . It will out perform the TFS intake out of the box and still be cheaper . If you want to jazz it up , go have it powder coated after the port work is done to it .

I would also ditch the E7's and the cam as well . That's small even for a 302 . With a 347 , I'd look at some ported Gt40's or used aluminum heads and a decent size hydraulic roller cam like a TFS stg 2 or even a Comp XE282 . Add some 24's if you don't already have them and let it rip .

[Aerocoupe]

I just sold my Cobra upper and lower (ported by TMoss), 1" spacer & bolting, stock bolting, six gaskets, and the vacuum lines for $350 shipped. Be patient and a good intake at a good price will come your way. I really suggest you talk to someone who knows a bit about camshafts i.e. Ed Curtis or Buddy Rawls and see what they recommend for what you already have so you can maximize these components. If you cannot get what you want from the current heads, cam, and recommended intake see if a cam and/or head change will help.

That Cobra intake would have been a nice intake for this setup !!! I agree with you about the custom camshaft . I am doing my very first custom cam for the 408W I am building . I use to always use something that sounded close and sometime its worked out very well and sometimes it hasn't . I am using a guy names Shaun T. out of Austin on this engine I am building right now and I'm hoping for good results .

I would say as far as Fords go . Jay Allen is probably the best in the business but he comes off as a total dick so I didn't use him for this reason .
