Dominator EFI ECU and distributor

Thanks for the suggestions.
The 4150 throttle body looks like a good idea, but, I am not sure about cfm. They seem to often be around 1000 cfm, would that be too much? The guys running the MSD throttle body setups tell me that cfm does not matter that much with injection, unlike with a carburetor, however, I am just not sure.
For the fuel rail, I was thinking that i would have to get generic fuel rail and drill it to the appropriate injector spacings.

The injectors are a bit of a mystery to me. What sort of flow would be appropriate? I am not building a 1000 hp engine, so, I was thinking something that is the same as an OEM V8 would work best. Any suggestions?

For modifying an intake manifold, I was thinking it would be best to mount the injectors at about a 45 degree angle, does that sound about right? Maybe a 30 degree angle would be more appropriate?
Here is an example from a Jeep inline FI conversion, Moses Ludel's 4WD Mechanix Magazine - Jeep CJ Inline Six Stroker Rebuild - Moses Ludel's 4WD Mechanix Magazine, HD Video Network and Forums.

The crank trigger is a possibility, but, I have to do some research to better understand how it would work.
