    Question What intake do you use, and why?

     



    It's getting hard to choose an intake with so many on the market now, so I want to know what you guys use and for what reason, and if it makes you any HP over a stock iron intake.

    Thanks.

    I changed to a edelbrock dual plane intake over my stock 305 because I had the engine bored .060 over and it made about 40 more Hp at the engine along with new pistons and a larger carb and headers.

    the boring .060 has little effect on power. intake choice is based on usage & application. John

    Stepside Let me rephase my post. I had my engine bored .060 installed new cam, pistons,rods,rockerarms, etc. and not liking the stock intake manifold, I went with an performance intake and a larger carb. Hows that!

    I have a BDS #8026T for my BBC. I went with it because my 1071 BDS Blower fits on it so good. HE HE HE
    "More power than the stock intake" .... haven't got it runnin' yet but I'm guessin' ... YES

    Correct me if I'm wrong: Along with a weight savings-(cast iron vs. aluminum)-aftermarket intakes generally will have better flow characteristics than oem jobs. You can get a single or dual plane intake. Single plane intakes are generally used for power farther up the rpm scale. Dual plane intakes generally work better at street usage rpm-showing better low rpm torque.They are much easier to drill for NoS WOOOOOPPAAAAAA

    Agreed Tech, so the application will depend on what kinds of demands your going to put on your engine?
    In other words if you just putt around town listening to tunes, the stock one would probably do. If your going to have your foot in the car alot going after the local squirrilly mustang owner you will need more fuel boost?

    I have another question, to you stepside 37, what is the purpose of boreing out an engine if it adds little hp? Doe's it not add chamber volume thus more fuel for ignition? I don't understand.

    Hey fast chevy, do you also have a motorized covered wagon? I think I saw a show on TV with your rides.

    Brick, generally boring an engine is to make the cylinders round again. if the engines cylinders are worn, & you bore it out to correct the problem, the power youll feel is from the fesh tight pistons/rings & cylinders. but if you had say for example a good running low mileage 350, took it apart, bored it .030 over & put in new replacement pistons, you wouldnt likely notice any gain in power.
    even on a fairly healthy 1hp per CI street performer,youll only see 5-6 HP gain per .030 over bore.
    alot of aftermarket intakes look like stock standerd 4 barrel intakes, but generally aftermarket dual plain intake make more power above 5000 RPMs than most stock intakes do. John

    IUse the factory aluminum intake cleaned up-for now. Somehow, i got an aluminum intake with an olds small block! Not, its not for a smaller engine either. After cleaning out the water runners and cleaning the intake routs, i got a nice sharp response. Since im broke, it will do for now.

    Covered wagon?

    Anyway, I've herd that the Edel Performer is not any better than stock, not that I was going to buy one.
    I'm thinking the Edel Air-Gap and the Weiand Stelth are the best dual plain intakes for the money. I could be wrong though.

    What about cold starts? I've got a iron intake with a ram-air setup and no heat stove, and it takes 15 min to get warmed up on a cool day. longer on a cold day.

    Fast depends on what stock intake your comparing it to, & what the purpose is. If your comparing it to the stock LT-1 intake of the early 70s, than no, it isnt any better. if your comparing it to your typical 4 barrel intake on most cars & trucks of the 70s & 80s, they are better. The differance is most noticable over 5000 RPMs in most cases. a typical 350 Chevy in stock form made power to about 4500 RPMs, so the stock intake worked fine, if you bolted a Performer to that stock 350, you probably wouldnt notice much, if any change.

    I'm not compairing anything, I just wanted to know who's using what and for what reason, just like the other thread on hotrodders you were wondering about. Which in fact is turning into a very interesting and informitive thread.

    I guess you guys over here just ain't much fer talkin.

    The Edelbrook does perform better than stock cast iron. It along w/a Carter or Edelbrook carb is a good alround combintion. Not for the track....for that I have a LS6.
