    Default intake/carb

    intake/carb? Im changing my intake manifold from stock to a elderbrock rpm air gap .my question is the stock manifold had a carb spacer and it wont fit on the new manifold should I just ditch the spacer ?or should I get one that fits?also am I going to have to tune my carb for this new set up?

    Carb should be close, ditch the spacer. New intake is looking after the spacer for you. Like anything do a run and check things out.

    Seems most people run a spacer. How come they don't make an intake tall enough so you don't need one?

    I'd stick with the space, even if it's only to isolate the carb from engine heat.

    Several do, Dart and Brodix( single plane), but a spacer for heat isolation is a good ideal.

    Running a 1" 4 hole or actually a Super Sucker 1 1/2- 2" could give you an additional 12-15 ft. lbs and 10-12 hp up to 6,000. The Super Sucker will help down low but will you feel an additional 15 ft lbs in your boat up against the impeller ?????

    yea I think so , haven't used the super but was thinking of ordering a couple . I have always found an open spacer to be worth at least 50 rpm when running continuous flat out against the impeller , on a std. height single or dual plane . must be making more torque

    I was thinking of the 1/2" super sucker under a single 1050 Dom. Turning 7400 in a hydro. Looking for more out of the hole.

    If stock was a cast iron quadrajet intake and your carb is a Weber or Holley squarevore, than that spacer is actually an adapter. Throw out the adapter.

    Use the carb direct on the intake.

    If you up the hp with cam/cyl heads and turn more than 5k I'd run an open 1" spacer.

    ========================

    I know Super Sucker's very well. I'm WD and two of them are mine. LOL.

    They are best for single plane intakes.

    More to it than this, but that's the generics.

    if anyone has questions please feel free ask. Phone is easier to help with the myrad of different engine combo's out there.

    I havent tried yet, but I have read that the RPM airgap responds well to a 1" or 2" open spacer...

    On my 2004 Engine Master's Engine we dropped the plenum divider another 3/4" and used the Super Sucker spacer. It's design seems to get a better signal to the carb. It's a good combo of a 4-hole and open spacer.

    In any case I'd drop the plenum divider 1/2-3/4" and put a spacer on it open or otherwise it will out perform the stock form.

    A few I've tried over the years:


    We did 78 pulls on the Engine Masters Engine in 2 day's. My friend Geoff Mummert ended up making an anti-reversion spacer out of a solid 4-hole spacer that really helped the engine come on at 3,000- 3,400. When we were at the competition we were talking to other builders and we were all talking about the reversion problems we were having. We told them about the spacer Geoff made and what do you know 1 year later Jegs started making a spacer just like what we told a few people Geoff did. I'll see if I can find a picture of the Jegs spacer.

    Yes it can.

    Usually if the carb is too small (common with dual plane intakes) and/or the engine would make more power overall with a single plane intake.
