3005 swap to 350
One little simple question, if I dump in a rebuilt 350 outta a IROC Z28 from an 1989 I have to upgrade my gauges too right, cause now the car is capible of more than 115.

Nope, you can leave the speedo the same. The 145 units bolt right in though, and you can take out the odometer roll thing and swap it so you get the correct mileage readings.
