Back in the day when I started the project ( 15+ years ago ) it was going to be a fast Sedan. Nowadays they make tons of Sedans that most likely will run circles around whatever mine might have become.
Kewl beans. I fought with original Cadillac EFI back about 15 years ago also. Tried introducing a controlled vacuum leak in the line to the MAP sensor. Tried screwing around with ECU reference voltage. Tried increasing fuel pressure by carefully squashing the pressure regulator in a shop press with some large sockets as fixtures. Yes I'm crazy. Nowadays there's Megasquirt. 4L80E too.
403 is a kickass engine. Largest small block.
