Re: Bolt on efi?
 

Sequential fired tpi with a stable computer sounds pretty cool.. The fact that many of the sensors haven't change muched shows that these old systems were pretty ahead of the curve back in the day.

Re: Bolt on efi?
 

It does sound very cool, way ahead of the older batch fired TPI system. The sensors all interchange for 96-02 Vortec 350, 305, and 4.3L. Looks like I'm going to get a Vortec harness and 0411 PCM to attempt this.

Sorry I went a bit off topic there. I will start a new topic soon once I have a prototype together.
