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.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
