In my case, buying the Holley HP EFI Universal Retrofit kit has a BIG cost savings. I saved around $500 per kit buying that way rather than piecing those components together. The wire harnesses, throttle body, billet pressure regulator, sensors, and ECM alone add up fast.

a modern 410 sprint has about 925 hp. Biggest change has been moving the throttle blades up high in the intake runners. I have seen mechanical injection setups modified to use EFI injectors. I think it's hard to beat the old school injection. Sprints have been on the leading front of max power from naturally aspirated 410 ci engines for yrs. The comparison would be cool!!

Definitely understand where you're coming from. I went the more elaborate route on mine. I went with better fuel pumps, aeromotive stainless pre-filters with SS elements, and aeromotive post-filters. I actually saved money on the intake manifolds - kept them and machined them myself (they flow a lot better than the edelbrock and holley versions anyway). All the fuel lines and rails are bigger than the Holley stuff. I wanted my system to be as high end as possible, but also wanted to be ready for the next time I have a nervous breakdown and get the upgrade itch for superchargers.
