350 TBI - something is not right

My truck has a 90 350 tbi. Hedders, dual exhaust w/crossover pipe, torque cam, edelbrock intake, stage 2 chip, newer fuel injectors, new wires, plugs, Fireball coil, low temp thermostate. My question is what would be the Ideal timing setting? I have it at 0 degrees right now. I had it at 4 degrees and didn't notice much of a difference. Some guy at a local shop said to keep advancing it til it ticks and glugs and then back it off until it doesn't under load. He said 8 degrees but won't that really mess the computer up, since it advances and retards it accordingly? I just want to make it run as powerful as possible. Could I put 454 tbi injectors on it? Will that mess the computer up?

Re: 350 TBI - something is not right

I'd do that but my truck was in a front ender before I bought it. The rad support was changed and it has no emission sticker. (gives me an excuse for having hedders and bottles with no catalytic) But like I was saying should I just leave it at 0 degrees?? If the temperature of the motor is too cold will it make the motor run less powerful and burn more gas?

My 87 350 TBI says to set the timing at 0 degrees, remember to unplug the advance wires when you time it! It's an engine code K, BTW. I think these were all the same into 91?
