It's a normal 440 with the Edelbrock ProFlo XT EFI manifold and fuel rails. Megasquirt EFI computer with full sequential injection and spark. No distributor. Crank position sensor is from a Taurus, cam position sensor is from a 6cyl jeep and the rest are generic GM except for the Innovate O2 sensor. The throttle body is an LS style that was slightly modified for the manifold. Coils are from a GM truck and injectors are from a Ford van. It's sort of a Franken-FI.
It runs/drives well and is really smooth. I still have some minor initial start up and idle tuning but I'll get back to that next spring.
