DD2000 or Drag2000 simulators are pretty much identical where as just about the only difference being that Drag2000 requires data on the actual car.

 

What someone would need is just about as much info as you can offer:

 

1)Displacement

2)Compression of your choice/needs

3)Fuel type (racing or pump)

4)Cylinder Head Chamber Volume

5)Intake/Exh.Valve Diameter

6)Street Ports/Racing Ports or Stock Cyl.Heads

7)Street Exh.Manifolds/Mild Headers/Racing Headers

8)Turbo/Supercharger or Normally Aspirated

9)If Turbo/Superchrg. then what boost/intercooler

10)If turbo/superchrg. then what efficiency of turbo/superchrg & intercooler

11)Camshaft of choice; spec's can be "Seat to Seat" or "@.050" Spec's".

 

Now you know why a cam's tech line will ask so many questions; everything effects the airflow of the engine which is relative to the intention of the car's purpose.

Gearhead240z,

 

Does your 400SBC have the 400's crankshaft also or has it been destroked: what is your crank's stroke?

 

Also what pistons do you currently have or are thinking about? Any Valve Reliefs and if so how many and what are their cc's, Dish cc's or Dome cc's?

 

I may be out of town the latter part of this week; I'll try to keep tabs to respond to your answer here-so bear w/me if I dont respond immediately after your answer. Just wanted to let you know if I dont respond immediately that I'm not ignoring you. :cool:

labrat,

those # seem pretty strong...i hope i can get that out of the engine....thanks for the reply

 

kevin,

i am using the 400 crank in it still. the pistons i am using now are federal mogul H107CP's it is only advertised as having a .100 dome so the exact cc's are a mystery to me.

Dome's, Oooh(?) :( Dont think I'll be able to help you; unless you can call the mfg/vendor selling them & ask for the cc's for your .040 overbore...then we will be able to play w/the numbers.

 

Till then, the only way of knowing is by cc'ing them w/one in the bore; the ole fashion way. So sorry.
