    Hello,
    I was recently given bad advice by Edlebrock to purchase a #2186 intake for this 1960 RB 383. Too narrow. Edlebrock is not at all familiar with this RB thing... Surprising. Can anyone tell me what intake I can use to convert this motor to a 4 bulb? And where to find/who to call?

    Most 383's are the B (or low B) family - except that one or two odd year 383 RB.
    The RB family uses a wider intake. I'm assuming they sent you a 383 B intake.
    I believe you can use any intake intended for a 440 (which is in the RB family). All RB intakes should interchange, all B intakes should interchange. Hopefully someone else can confirm.

    What is the 383 on, or originally from? V67 is right, 2 different 383 engines were built during the first 2 model years of that displacement.

    You might find a good manifold at a Mopar-specific (or old iron) junkyard. I've also seen them at swap meets.

    2806301 was the part # for 4-bbl intake manifolds for 383 and 440 engines for the 1968 and 1969 model years. You might look at a picture of one online, and see if it has the same bolt pattern as yours. Note that these were for the Carter AVS carburetors. The AFB manifold would be different.

    That can’t be. In 68 and 70 the 383 was B and the 440 is RB.

    There was a "RB" 383" in 59 &60 only. It had a 4.031 bore and a 3.75 stroke. The regular 383" engine was 4.25" bore and a 3.375" stroke.
    LB and RB intake manifolds are not interchangeable. Both have the same bolt pattern but the "RB" is wider. Heads are interchangeable.
