    Default 1999-up LS-1 fuel pump , good for 500 HP? Atomic compatible?

    I have ordered my tank / pump combo from Rock Valley Antique Auto supply, and they use an LS-1 pump in their system, I am unsure if that is a broad statement or if there is a whole family of LS-1 pumps for many applications. They did ask me about power output and line pressure requirements, but they seems unaware of the exsistence of the MSD Atomic system. I told them possibly 525 with my 451 stroker and probably around 60+ psi on the rails, is there any reason I could not run this pump successfully?

    It should as long is it isn't a stock F-body or Corvette pump. Those only supported about 450HP before they started falling off in pressure.
