Adjustable Holley 2300/Rochester 2G Two Barrel Carb Adapter

awesome product.

Perfect fit, and adjustable.

I have purchased many of these adapters.

Used on small block Chevy's, demolition derby cars. I like it because the studs bolt into the aluminum plate, the adapter part isn't stressed like cheaper adapters that crack.

Great adapter

Use on sbc demolition derby engines, stronger than pot metal adapters that crack, able to use Holley or Rochester carbs.

Good product

Very nice

Yes would buy again

Worked fine had to 5 the bottom plate to miss EGR plate on the 350 Chevrolet intake

Would buy again. Hardware included fit as needed .

Good quality product, Effective in balancing cylinder temps.

racing parts

For racing and all working great

Adapter for corvair

I have an adapter to fit a single four barrel carb on a Chevy corvair I plan to use the adapter from speedway to place a 500 cfm two barrel on it. I don't know if it works yet because I haven't used it yet. But i will let you know.

Good for adapting a Holley 4412 to a 4 b

I have purchased and still use two of these adapter plates to mount a Holley 4412 onto a stock SBC 14096242 intake to meet local Street Stock racing rules. This is the cast iron copy of the Z-28 High rise manifold. The plate works well for this purpose but you may need to modify the outer slots to make them wider. Example: to mount this plate using ARP 200-2401 studs instead of the provided Speedway 13560 studs onto the 14096242 manifold, I had to machine the slots out to allow the plate to fit over the studs do to dimensional interference caused by the slots being too narrow and/or off center to the SBC stud mounting holes. Note; this may be an issue only on this exact manifold and/or only when using the ARP studs, but this has been my actual experience. I purchased my two adapters 5 years apart in time and had to perform the same modification to both. It is a good product, but don?t be surprised if you need to modify it slightly to work on a stock SBC manifold.
