I found a full harness and computer from a 88 Chevy 1/2 ton 350. It has
everything but the O2 sensors. I was told a 4.3 throttle body will work, but
I bet I would need bigger injectors.
TO make a long story short, does anybody know of a site that lists
everything I need to do to my 85 K10 350V8 to convert it over to TBI?
The parts are cheap but won't last long. Just need to get some info before I
plop down the cash.
Really, all you need are the injectors, all of the sensors, the computer and
calpack.mempack and you should be good.
4.3 TBIs are just like 5.7 TBIs, but you will need the larger injectors.
You'll also need a 5.7 chip and calpack/mempack I believe, though the
computer module itself is identical.
So basically, you're better off getting everything from a 5.7 because
purchasing the right parts might end up negating the savings on the 4.3
ECMs may be the same -they may not be. On my '90 K1500, the ECM was
completely different. I didn't even have a calpack or whatever it is
called. All I had was one main EPROM and a blank spot where it appeared the
second may have been placed in some applications.
Check part numbers before making a decision on this.
The computer and harness are from an 88 silverado 350. The throttle body was
from an 88 astrovan.
The problem lies in the sensors. He doesn't have them. Motor is gone. Just a
complete harness and computer. I was under the impression that I didn't
necessarily need all of the sensors and the computer could be programmed to
run without them.
Also, can you run a standard 4 or two barrel intake or must it be
specifically for a throttle body? Do they make adapters from one to the

You MUST have all of the sensors and you MUST have the proper TBI intake.
If you can't find an available TBI intake, buy an Edelbrock or
something...might as well get a little more performance out of it.
