I'm assuming macDad has stock Merc manifolds so I entered small-tube headers with mufflers and compared the cams from there. Yeah, you can get some really impressive numbers by manipulating the exhaust but the process I used was to compare cams using the same factors in the other categories.

B.T. that's correct. I'm amazed at how close the DD numbers are as compared to actual corrected dyno results though. My own supercharged 509 (I only ran one on the dyno) was within just a couple horsepower and torque throughout the chart.
tmdog, these are all big-blocks we're looking at on this particular thread but the small-blocks I've run through the DD have looked pretty good too.

I put my new setup for my small block into the DD2000 and it spit out 571 hp at 6000 rpm and 526 lbs trq around 5000 rpm If memory serves me right.
Sorry back to big blocks.. I've been trying to drive crazyhorse nuts

If I put up my specs Crazyhorse would you sanity check my hp/torque results? I am getting over 500hp and 550ft-lbs of torque with my parts on dd2000 and that seems high. I've felt like I made an error somewhere, but not sure.
Let me know and I will post them.

Believe me, it's not that hard to get 500 hp out of a 454. We do it with all Federal Mogul parts, even the camshaft. Sure, post all the info and I'll run it through. be particular with cylinder head info, compression ratio, carb and intake design. Cam data needs to have all the opening and closing event timing, as well as lift withthe rockers you'll use. Don't forget exhaust.
