    Default Single Plane Rat Intake Manifolds-Which one?

    Which one of the single plane BBC manifolds is best for a N/A 496 v drive lake cruiser motor? Alum. Rec. port heads.(310cc runner) I hear a lot of guys saying they like the DART manifold. Is this because it has a smaller plenum that helps boost carb signal at lower speeds 2000-3500rpm? Does a Dart manifold belong with Dart heads and a Brodix Manifold with Brodix heads?-etc. -Or is it back to just the best optimum combo of parts for the job at hand?

    The Merlin has the beter midrange of he two, especially with a dominator carb. Up to 6200 rpm or so the Merlin is defenitly better. TIMINATOR

    Dare to be different, if it turns out great you can claim you planned it that way.

    What is going to be your all out max rpm on this, 62-6400?

    From what I've seen and heard, the Edelbrock is goign to have the overall power advantage, especially on top, followed by the Dart. I had heard in the past that Dart heads were made to work with their intakes, (or vice versa). I'm not sure how true that was, or if it was a rumor started due to a lot of mis matching (poor machining) going on. Just about every aftermarket intake is going to have it's differneces, and so are heads, as far as fit and physical compatability.

    Max Rpm 6200-6400. -design parameters with the goal of a mid range motor with lots of torque.-not a top end screamer, yet not a barely warmed over stocker.-I posted this subject hoping to spark some discussion about the theory that goes into intake selection. After some original research, I was under the impression that a mid range motor would respond better to a tall dual plane maybe with a cloverleaf spacer.(ebrock airgap RPM) -Now after several conversations with knowledgeable people, there is a belief that the larger displacement motors (500"+) seem to like a open plenum single plane. Is this simply just because of the large volume of the cylinder coupled with free flowing ports? Or piston speed with a stroker crank? -Sorry to be so full of questions, but I'm trying to learn so I'm not just throwing together a bunch of parts together.

    Pretty much yes to your questions...Single plane open plenum intakes are a little less responsive in tyeh midrange on non-stroked, under 500" big blocks, but get into the larger displacements and srtokers, and you're exactly right. Increased piston accelertion along with displacement make those intakes work much better overall. It's all based on signal to the carb.

    are we talking highway motors or jetboat millsb/c last time i check a jet could give 2 f-s about midrange.but some will argue that point also.so if you argue this point, when was the last time you had to build rpm in your jetboat

    single plane on a jet boat all day

    im sure the wilson edelbrock vic will beat all the others.but it will also break your damn checking accountlater travis

    The computer dyno stuff I have ran with single plane over dual the single plane is better thru the entire RPM range from about 2500 on up over the duals. But the question was which single plane intake.... how about the victor jr for most boat stuff as its peak is not 8 grand like a lot of the others, and not many of us take a boat to 8.

    how about some consideration for the Edelbrock Super Victor or the Team G or the Weiand Stealth??...just my .02 cents
