Sequential Multiport EFI

thanks guys , The reason I started this thread was to learn and I'm not hung up on anything really , I understand the basics are the same and it's going to cost for a turn key setup , I 'll look into the Holley setup before I comment , the sequential part of the equation is more what the suppliers are selling not my wanting sequential , I would like to get the setup with the most control over whats going on I just don't know enough to start buying bits and pieces to cobble together a system myself . I am using the eddy proflo2 as a reference point since it claims to be complete including a distributor and fuel pump , they even have a sump setup that eliminates the return line to the tank which seems like an interesting solution to having to drop the tank and run new lines.
