    Default Replacement for R 84018-1 Marine carb

    I can't find this number on the entire list. What the heck? It's a 1991 Chevy 350 Kodiak marine engine and I want a direct bolt on replacement of my old carb. Anyone have any ideas what the cross reference would be for a new one?

    Call Holley Tech Service (Link) for carburetors that aren't in their numerical listing.

    Hi. I have a .030" over 454 engine, GM Performance aluminum heads, roller tip rockers, GM Performance intake manifold, not sure which cam, 750 Holly carburetor, 80508-1, THY350 transmission, 3.25:1 gears.

    I'm getting terrible gas mileage. What can I do to the carburetor for better mileage? Thanks!

    Hi Guys, I just purchased a '69 Camaro with a 454 and a Holley carb. I'm in Australia, the engine was fully rebuilt in the USA, I have limited History on it, as I got the car through a wholesaler. I'm not a mechanic and have limited knowledge. Can I please have some help? I assume the carb is 4 barrel double pumper, possibly a 750, I can see that there's a metering block missing, and the choke has been removed, and appears to be held slightly open with some wire. The numbers on the top are 8R 8026, there's R 37 on one side, and it's stamped 3310-10 on the front, then 2784 below. I really want to know what I have, also if I need to replace parts, or even upgrade it. The car runs fine, however it's running rich. I can send pictures if required. Thanks.
