I belive you have to get your Prom burned for that. A custom prom is in order.
What do you wanna do to your car?

Why would these mods require the removal of the 9th injector?

Kinda what I was getting at.
Those look like some mighty nice mods you are planning. The cam seems a bit to high though.

well, im lookin to open up the 305 a bit, and i figured that if im gonna have the motor apart for a bit ill remove the extra injector, i wasonly lookin at it because if the 89-92s didnt have it there might be a restriction with it but im only tryin this instead of switchin over to the 89-92 set up

The 9th injector is only there to squirt a little extra fuel in during cold starts. In 89 it was eliminated & the ECM was reprogrammed to provide the extra fuel via the standard 8 injectors. There is no performance advantage in removing it since it is not a restriction, it was only done to simplfy things since they often went bad.

Street and Performance makes two pieces to block it off. One plug for the rails ($15) and one plug for the injector ($5).
