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.

Ill sell you my TKO600 complete set-up !
