From the dyno numbers I've seen on carbed mod motor setups, they make some nice peak numbers but area under the curve is sacrificed.
Definitely interested to see your results with the same amount of nitrous.

Using a 1" - 1.5" Wilson Manifolds tapered carb spacer can help the area under the curve. I have not seen any Carb Mod Motor dyno tests using this tapered spacer yet.
In the MM&FF Dec 2007 issue, a 4.6l DOHC intake dyno test was done on every type EFI & carb intake avaliable for this motor. It's a very good article and very interesting. A Sean Hyland 405 hp built motor was used that has ported heads & stage 1 cams and 1.625" primary Hooker Headers. With the factory EFI intake setup it produced 408hp. The Sullivan with a 750 Holley produced 436 hp. Like you were saying the area under the curve is way down. Not the choice I would go for a street machine.
Jeff Chambers got me thinking a little while back when he was talking to me about possibly going carbureted. Then when I ran accross a new Sullivan 1-101B intake for $500 shipped, I jumped on it. For the track, I like the idea and am willing to give it a shot, especially with the nitrous on this setup and backing it up with a Liberty Gears modified/face plated TKO 500.
