No really looking to buy one, just have messed with a knock sensor on my engine and had difficulties with a good location.
Something interesting though. I do own a new design vortec 3000 4 cyl. Maybe a 2008 model. It has all the good bells and whistles.
One piece rear seal
individual intake ports
Injectors bungs cast into head
Location on driverside of block for knock sensor.
Crank position sensor
4" bore
This engine still shares our head block bolt pattern and front cover.
