DurangoBoy, don't get pissed with the our low hp estimates. I know I prob would have in your situation, just realize that if you want 400+ wheel hp, and that's your goal (not a fun torquey DD) than you might want to consider putting your project on hold till cash permits some more aggressive parts. Because come dyno day, I hate to say it, but you'll likely be disappointed. Either step it up or install some juice along with your new powerplant. But for a DD, I think your setup is pushing the comfort zone as it is.
When HotRod tests these cookbook engines, they test them at the crank, with no accessories, with gigantic open headers. And after hours and days and weeks of tuning, they make some pretty impressive numbers. Numbers that you will never see.

Stock 400 rod 5.5 inches. Pluses- quick low end torque.
Negatives -weaker than 5.7, not good after 4,500 and heavy piston side loading.
