buddy of mine has a 91 s10 blazer with a tbi 350 it has a older style 350 with a aluminum intake with an adapter for the throttle body
problem is that it will run on the 4.3 computer that the truck came with but it wont idle and runs fine and pulls strong, when he puts a v-8 chip in the 4.3 computer it idles fine but backfires out of the throttle body when you get more than half throttle, today he put a whole computer and chip out of a 92 silverado with a 350 and it would hardly even run and move what could be going on
this motor has no egr and a little more cam in it hardly noticeable
