    Default Best Single Carb Intake For A Stock BBC

    Howdy,

    I am looking to upgrade the factory intake on my stock BBC with one of the numerous single carbed intakes choices on the market. I was thinking of going with an Edelbrock AirGap RPM intake as I heard some good reviews, but am wondering what experiences you may have had with this and any other single carbed intake that’s available. Also, does anyone know of a link to a BBC intake shootout perhaps?

    The boat is a 1993 Caliber 1 Tracer (18' Eliminator Bubbledeck) and the motor is it's factory stock 97 hour old Indmar 454 with a 750 Holley 4160 carb. It will run approximately 65 mph with the stock motor, rideplate, and Place Diverter. I have not GPSed it yet but I have passed my friend's boat quite quickly as he was doing exactly 59.8 mph on the GPS.





    Thanks in advance!

    If you're happy with it, why do you want to change it?

    Everyone will have a different opinion, if it was my boat I would run a Weiand Team G single. Jets operate at a higher RPM get some good flow up there.

    I am happy with it. I wanted to show how happy I am with it by buying it a new intake I think the new intake will give it that nice finishing touch while hopefully also gaining a few horsepower or even just broadening the power band. I don't think any of us can leave things alone.

    Just the intake I swear! Ok maybe roller rockers and a MSD. Oh and don't forget the droop and loader! That's all I promise!

    'Cause he wants 'more happy?

    This id kinda old school and automotive related but we used to weld a 1" this plate to the top of an edelbrock performer and machine it for an 1150...one a 454 with a medium size roller they pulled like a sob from 2800 to 7800..and even fuel milage wasn't that bad it ya could keep from spinnin it

    Here's what I went through when I had a fairly stock BBC on a previous boat. It came with a Performer 2/0 but I changed it out for a Torker that I had laying around.....no change.
    I changed the Torker out for a Team G single plane....gained 100 rpm.
    I was like you and heard a lot of good things about the RPM Air Gap so I picked up a used one for $100.00. Swapped out the Team G with the Air Gap and gained 200 rpms.
    I did try different sized carbs and the best all around for my set-up was a 750 vacuum secondary. There wasn't any difference on the top end between the 750 VS, a 750 DP and an 850 DP. The big difference was in fuel consumption so I just stuck with the one that got the best mileage.
    The engine had stock large oval port heads along with log exhaust, tached out at 4800 from the 4500 it had with the original set-up.

    Default intake

    Your on the right track with an air gap intake. If, you gain any horsepower your only talking a few, and you'll barely see the change in rpm's. I'm guessing your seeing 5,500 +/- rpms, and you don't need something that will breath to 7,500 rpms, it will just not happen.

    RPM Air Gap. I have ran mine for three years. I wish they made one for a tall deck.

    they make spacers, so you can run any bbc intake on a tall deck.

    Thanks everyone for your input.

    Cas, your detailed comparison was just what I was looking for. Thanks!

    Looks like I need to find myself an AirGap now!

    Pony,
    It might be a good idea to pull a valve cover to get the casting # off the head to see what you've got before you go out and buy. Hopefully they're at least large oval ports

    That is a good idea. I will try and get to them this weekend. It would be a nice surprise if I found they were HUGE rectangle ports!
