Here is a link to Head Flow data. You will have to input it into the program and then save it to your hard drive for each head that you want to model.

What other files do you want? I have a Cam Disk with lots of cam files, but not all. My Cam Disk came with Dyno 2K. Others I input the specs and save to the hard Drive.

Wow how accurate is this thing because I am getting some impressive numbers for both HP and Torque. Should my cam specs be set to “seat to seat” or “@.050” I am putting in the lift at valve measurement in. When I put in the seat to seat I get some Nice numbers, but when I put in the “@.050” setting I get numbers that seem very low to me. I have read the help section that came with this program but it does not seem to be all that helpful LOL. I can post a link to my dyno file if you would like to see it.

I have been trying to reproduce the numbers from the Hot Rod mag build. I come up short in both torque and horsepower. Of course I don't know what their head flow was, or what kind of intake manifold they used. Also I can't simulate a 'Y' pipe into a single flowmaster either. The best that I get is 368 HP @5000 RPM vs their 380@?, and 427 ft-lbs torque@3500 RPM vs their 468 ft-lbs @? RPM. Overall I think Dyno 2000 gives me a fairly good simulation of this motor.

Here is an explanation of why you get different results between Seat-To-Seat timing or 0.050 timing.
The Dyno2000 will simulate camshaft
motion for both Seat-To-Seat and
0.050-inch cam timing. However, the
internal simulation model requires
seat-to-seat event timing to accurately
calculate the beginning and end of
mass flow in the ports and cylinders
and must derive seat-to-seat timing
from 0.050-inch figures. Unfortunately,
this cannot be done with high accuracy.
So, whenever possible enter
seat-to-seat timing to obtain the most
accurate simulation results.
The Hot Rod build cam spec is @0.050, so my simulation has that error. I should try to estimate the seat-to-seat timing and run that.

Here is the link to my .DYN file, alod in there will be 2 other cam choices that IO might use, they are bigcam and small cam.
