The R/W and McQuillen 2x4 manifolds are the best High Performance units out there. The A Bruneau Performance single 4 manifold, Speed-Port 7000 is the only High Performance 4bbl made at this time. If you want more go to Hogan's manifolds and get one built. Then modify your hood.

What carbs will the new intake accept?

Monk,
Stock carbs inline or Holleys sideways.
You might have room to drill for others but this should cover most of the market.
Thanks for inquiring.

The manifold looks Great Carl. In my opinion, you have done a great job tackling the task and providing the manifold to us consumers in a very professional manner. :appl:appl:appl

Now I need to work on finding a 6-71 Blower, I never thought I would head that direction.................:crazy

Manifold looks great Carl. Do you guys have any HP numbers to compare say the 881 to the Edelbrock dual 4 to your manifold? I would be curious what gains could be expected with it.

There is room on the pads for the bolt pattern but it would be very close to the Holley sideways pattern.
It could be done , better if you plugged those holes first.

Would love to hear of any performance comparisons :).

Well that other fella from down south claimed it was worth 100HP more over the 881 :dunno

It depends on what you put it on. A mild 409 inch engine won't see that type of gain but, a 470+ inch engine with a big roller, extensive head modifications, etc could definitely see 100 hp increase. All depends on what the build dictates.
