Making a little more progress with the 461. EFI is a Holley HP system. While not the cheapest solution, I like the Injector Dynamics LS style injectors. These are the shorty ID725 high impedance injectors mounted on a Torker II EFI intake, ported to match the heads by Dave at SD Performance.

Fuel rails are Edelbrocks.

I fabbed up some stainless standoffs to raise the fuel rail slightly higher to accept the 48 MM (O-ring to O-ring) injector height. No changes needed to the intake.

I also added a 1.5" Wilson spacer under the throttle body, this buys me some additional plenum volume, and raises the throttle body high enough to let the linkage clear the fuel rails.
