I call into question the accuracy of DD2k. I took an atricle off chevyhiperformance.com called Cylinder Head Flow-Bench Database. Under the Edelbrock Performer head they had a 355 engine they said they dyno'd at 420hp and 440 ft-lbs of torque, using the Edelbrock heads. After typing in the specs of that motor, including the flow numbers from the heads, the exact cam specs, CR, Manifold, etc. DD2k only gave me 368 HP and 392 torque. That is a whopping underestimation that gets me big-eyed about other motors I have dialed up on the program. Has anyone else had this kind of miscalculation with the program as bad as this?
