I have a 1990 Chevy and I just rebuilt my 78 355 and made it full injection and now it does not want to ideal after I adjusted the rockets and set the timing. I think its something to do with the t.b.i. how do I adjust the ideal on the full injection?

SOURCE: rebuilt engine valves not adjusted.1970,s model

this is easy depends on how many cylinders ,say a six pot ,this has 12 valves ??correct, so what ever you adjust must add up to 13 ,right so with number 12 down number one is up with a gap so adjust it 12+1 = 13 ----11 down adjust number 2 ,,11+2=13 easy
a four cylinder has 8 valves witch add up to 9 ,number 8 down adjust 1 this adds up to 9 ,now nothing could be simpler

There is some adjustment. But you may have something else going on. When the tilt gets old the pivot pins get loose and the holes get egg shaped. If this is what is going on then you might me wasting your time.

The float inside the tank needs to be replaced. or one of the wires has a small short in it.

There is no adjustment for a 96 camaro. It has coil packs, the computer adjusts it to what it needs. Why are you wanting to adjust it? Is it not running right or just trying to tweek power?
