I have a 92 & 94 s-10 blazer, one has TBI and the other is CPI, the 92 is TBI, I want to put the 94 motor in the 92, but I have to switch intakes so I can keep the TBI which the 92 is set up for, here's the problem! under the intake of the 94 there is a shaft the looks like it runs off the timing gear, when I set the TBI intake on, the shaft hits the bottom of the intake when I rotate the crank....Does anyone know what this shaft is????

No WAY

The balance shaft balances the engine.
