Okay, i installed a 91 350 TBI in my 91 S10 which came orginally with 4.3 TBI. I kept my ESC box from the 4.3. Would this cause any problem with my motor? I have noticed a rich condition, and am not sure if this is causing it. Also, is there another spot to install the knock sensor exept for the stock position? my motor mount is in the way of installing it i the correct spot.

thanks

I used my ESC module from my 4.3. I haven't had any problems with it.

Also, the Astro V8 conversion motor mounts look alot like the S-10 mounts. I didn't have any problems with the location tho. I put mine in the passenger side.
