FWJ you should check out the MSD forums or contact MSD themselves. Atomic "1" supports 650hp with a good enough pump. I had one on my Pantera running 640hp and it was pretty good. Excellent starting, hot or cold, ~20mpg on a 1,500 mile trip including track time. I set the regulator to 55 psi, I think. I used a Bosch 044 pump and set non-pwm with regulator, idle at 900rpm with 17in vacuum at idle, no problem with power brakes. I moved the Atomic to a Mustang and works well there also. You will need to run with timing control to get the full advantage.

Here are a couple of old threads. https://forums.holley.com/foru...ndard-kit-to-high-hp
