Advice on intake setup

[Knanthrup]

I\'d like to get some advice from some of you experienced guys out there on what intake setup to go with. I realize that single and dual plane have different purposes of low and high end power, but what\'s the better choice in your opinion? Which one is more wise to go with for a truck application like ours for street and strip use?



I\'ve mostly been looking at Edelbrock intake manifolds because I have heard good things about them and I can get away with 10% above cost phttp://www.s10v8.com/images/smilies/smileJap.gifs through my work... then again I can get other brands too but Edelbrock is a larger dealer. So anyways I\'m browsing through their options and I\'m trying to decide on the setup. If I go dual plane then it\'s probably between the performer series and RPM series. I want to emphasize that this thing needs to pass emissions so I don\'t want to stick myself in a bad position. Anyways would it be wise to go with an air-gap model or would just a regular performer be just as good? Should I get an RPM series or would emissions be a problem?



Then if I go with single plane I\'d be looking at the Torkers or the Victor jr. I have heard people hail the victor intake but it sounds to me like youd have emissions problem out your rear but maybe I\'m just misinformed.



Alright so on top of this all I need to figure what carb to run. From info I gain here and there I assume a good size to go with is a 750cfm carb. Now...brands... Is Holley worth the money?, they seem to be marked a little higher than others. Is is good to go with edelbrock from the top up for the value and performance or is that a bad idea? Either way I just want a good setup and I will need a choke, preferably an electric if it isn\'t too complicated.



Ok so I\'d just like some more opinions and suggestions because I have no experience with this. Please keep in mind I\'m on somewhat of a budget and performance value is my key. I\'d appreciate any input I can get, thanks!

i have all edelbrock on my truck and i am very happy with it.. check out their performace packages to get the most outa ur motor! for ur emissions i dunno about that one, hopefully someone here will know . i don\'t have to worry about emisson testing yet anywas , goodluck with it thou!

RPM AirGap

I run a Performer RPM with 1\'\' spacer and a holley 750 with an electric choke. Your intake choice should be in the same RPM range as you cam. Dual planes work better for bottom end and midrange power, a single plane works better for high RPM power. I\'m running a 292 duration 480 lift cam that works from 3 to 6,000 RPM. I love my holley, would never go to anything different. As for emmisions, i don\'t know what type of laws you have there.

i have a wieland stealth with a 1\" spacer and a 600 holley w/electric choke.

i like the victor jr. intake myself. i ran it on a 350 stock bottom end with headers and it was a very torky motor compared to the stock intake.

rpm air-gap w/ 750 edelbrock

[Knanthrup]

I just want to start out by thanking all of you for your responses.. it really does help me a lot!



So you RPM air-gap people seem happy with your setup. This will probably be on the top of my list then. Has anyone had experience with emissions testing using that intake? I\'m just curious cuz I\'d hate to waste a few hundred bucks and find out I\'m stuck with useless parts.



Also If I went with the RPM air-gap and 750 carb what would be your suggestions for a good cam? What brand would make a good value? Lift and duration? I\'m hoping to not spend over 300 bucks... and the less the better. Keep in mind I don\'t want something too radical..well I do but I can\'t because of the above mentioned reasons. Thanks again!

The RPM AirGap is not emissions legal it doesn\'t have an EGR valve. You\'ll need a Performer or similar intake, but if you live in a hard emissions state then you\'ll need to convert to fuel injection for an engine of equal or newer year and have all of the smog stuff on it.

[Knanthrup]

Well the original engine was carb\'ed so i don\'t have any doubts that a carb\'ed engine can pass. It\'s just making the right decisions on what to buy when putting it together. There is no way in hell I would go through the trouble of making is fuel injected... for me it would be way too complicated, expensive, and I\'m just not smart enough to do it right http://www.s10v8.com/images/smilies/icon_smile.gif . I guess I might have to go with the more moderate stuff to be on the safe side but I\'m sure I will be able to work something out one way or another... even if I have to go through emissions with it set all the way lean running on alcohol.



Oh and I couldn\'t care less whether it\'s considered emissions legal or not - as long as I pass and they don\'t have a fit if they look under my hood.

I think catalytic(did I spell that right?) coverter would help.

[Knanthrup]

yeah, i do plan on running cats, hopefully that will do a lot of the work in itself... then maybe add a cutout for all the times where i want to let loose http://www.s10v8.com/images/smilies/icon_smile.gif

Im running a Victor Jr. intake with a 750 Holley. It all depends on your cam size, compression, converter, gears, etc. The key is trying to match the components. With my set up, I knew that I wasn\'t building a torquey engine and I matched everything to RPM band. Everything initially starts between 3000 and 3500 and shuts off around 7000. Thats why I went for the Victor Jr. because I believe it has a 3500 to 8000 band.

I\'m running what most of you will have never heard of..a holley street dominator. An old

manifold but works great with what I have in the engine for a combo. I also run what you guys will think is junk for a carb....a Quadrajet!

Yep! I love it cuz it gets great mileage and has the extra punch when ya stand on the go pedal. It is the 750cfm model and has been tweaked alot.



You need to put the motor together as a complete unit not just as one part here and one part there. It doesn\'t work! Trust me I\'ve been building engines longer than most of the fine people here have been driving...25 +yrs.



Call Comp cams help line for the cam and do alot of asking around to your local machine shops as to what works for them. Also com cams can help you with most of your questions.



Good luck on your search cuz a bad choice on the manifold can really suck.

I once destroyed a 350 in a 76 Nova SS that I salvaged everything but the short block from. The engine passed all emission tests when it was together. I now have a newer short block that I installed the old parts on. Among the old parts is a Torker single plane intake and a Holley 750. They worked great for me, too bad the rods didn\'t hold up.

it\'s hard to beat the edelbroke preformer and rpm perfprmer...they have great low end power and high end power with great driveablely and the rpm have a power range from 1500-6500 and the preformer is from idle-5500...i belive that they a 50 states legal....

[Knanthrup]

Well i know the performer itself is emissions legal but I\'m pretty sure the performer RPM is not. I guess I\'ll end up going with the Performer which shouldn\'t be bad, I was just trying to get the most performance possible within emissions standards.
