I have one on my 290 with a 500cfm Edelbrock, it was a low end game changer compared to the stock 2 barrel intake and 500cfm Holley.

I just have remembered that I have a square-bore Offy intake. Great, another choice. Maybe I'll have to do an intake comparo.

Dual Port or divided single plane 360? The Dual Port has a 4 hole carburetor pad. The other has 2 and is divided side to side, with a notch.

I had the standard square port.

I have had both the dual port offy and I have the 360 equa-flow which I think is more on par with the r4b maybe a little more top end power than the r4b in fact I will say it does have more. But for low end torque the offy dual port is the way to go IMO.

I'll have to check the one I have. I think it's two with the notched divided, but not positive.
