I have 468s with Weiand team G single plane intakes with Nickerson 830 carbs. Would I have better performance with dual plane intake??Also rec.heads and S-M exhaust.

Not enough performance change to justify the cost. I would say maybe a 10-20 lbs increase in mid-range torque and little to nothing on the top end.

The Team G is a good manifold. For the rpm's the boat runs, a single plane is the way to go.

Depending on your pistons, cam etc, unless you're running like a pig down low at the moment, i'd say if it ain't broke, don't fix it.

The rect port heads need to breathe and the Team G will do that. If you're lacking low end, try an HVH SS Carb spacer, they're cheaper than a new manifold.

If it's all good now though, leave well engough alone.

You will gain low and possibly mid but top end will suffer. You wont be happy trust me.

the carbed hp500 uses a singel plane manifold.
