[Gmecm] Chevy 350 Carburated to TBI / TPI?

[Aphelion79]

Ok another couple of questions I have for the setup:

I was wondering if the TBI systems used on the '87+ Truck 350s were fuel 
only, or did they control timing as well? 

On the GM 151 4cyls I've had experience with they used a computer 
controlled timing curve (basically the same idea as a vacuum advance, 
I.E. the computer has NO idea where the timing is in relation to the 
crankshaft)  I also know of other types of engines using complete timing 
control where the use of a crankshaft positioning sensor / knock sensor 
is used...

Also, for an O2 sensor, do you need one for each "side" of the engine? 
(Where as my previous knowledge is I4 and I6's, I only have one exhaust 
manifold! =D )


Also these systems are all OBDI, because to my knowledge OBDII didn't 
start up until 1996?  (Dunno where I got that year from, but for some 
reason it comes to mind, lol.)

Thanks for the support everyone!
