The OP was talking about dual EZ-EFIs, which is a bunch of money. Heck, one of those is a lot of money to me.

Holley's controller is multifunctional and I believe will run port EFI for less than the price of two EZ-EFIs. But I could be wrong. On the Race Engine board, check out Monte Smith, he works for Holley and will be the best one to talk to.
