Ok I believe it's a accufab upper I have to look I know the tb is accufab but not sure of the hat bought it from a board member so gotta follow up but knowing it's a kb accufab power plate helps
Doesn't look like my Precision. I have one of every upper plenum ever made for the Turbo Buick. Unless it's a older Precision that I've never seen. Someone correct me if I'm wrong.
Jason hit me back they are percision how old or new I don't know he said the raised boss in the back driver side is there because precision makes the throttle body sit higher so you can run a 4 inch up pipe without any issues
