Try running this combo for me!!
 

598" BBC (4.600 X 4.500), naturally aspirated, 10:1 compression ratio, Dart 355 Pro 1 CNC heads, solid roller cam 264/270 duration at .050", .711/.721 net lift on 114 + 4 installation. Carb is a 1500 CFM Holley Dominator, exhaust is full runner header like a CMI Tube Top with 32" runners and full MSD ignition. Intake is a match ported Dart single plane.
Thanks,

You need to post the cam timing events for us to run the program.

Here are the .050" cam timing points with the cam installed on 110*. IO 22 BTDC, IC 62 ABDC, EO 73 BBDC, EC 17 ATDC. Do your dyno programs actually have Dart 355 CNC ported heads?
Thanks,
Craig

Here is a screen shot of the pics on heads Wette Vette. The airflow file is really a necessity from my limited experience because heads make such a huge difference in results.

My program shows 700 to 765 depending on the eff. of the heads. My program doesn't have the 355 cnc so I used ported 360's for the higher number. Peak was in the 55-6000 range.

I have the Dyno 2000 and think it needs more specs stored in the program so that the user can jump around with different actual mfg part specs without entering alot of info. BBB
