Hello from WI.

[Avalanche]

I'm new to EFI conversions and I have a big project with hopes of finding help here. I have a 1986 Chevy
4x4 that I'm swapping in a cadillac 500 motor and a 4L80E transmission. I am converting the 500 to TBI from
a chevy 454. I have the throttle body and adapter. A brand new engine wiring harness for a 1992-1995
chevy truck. Some of the sensors. A cadillac engine to chevy transmission adapter. The PCM I think I need is the 16197427 to control the tbi and transmission. I know there's more parts I need but it's a start.
Hope this site can help me with what to do and what I need. Thanks

Sounds like a cool project! Thanks for checking in here but need to start another thread in GM EFI section with above information and we will start sorting through it and help you get going!
