I just put a 2000 vortec 350 moter in a 1990 chevy truck with a TBI.I got a new intake, do I have to do anymore mods to make this set up work and run top shape thanks

HUGE goals..

Do you have the entire engine wiring harness and appropriate engine control module?
As well as the proper throttle control linkage?

Plumbing the coolant and exhaust could be another major hurdle.

Let us know your progress.

Thanks I will see how everything works out for me

If you are using all of your old linkage, wires, etc. for the TBI then you should be fine as long as the relative location of things have not changed. I.E. the water neck is in the same location and pointing the same direction. You are basically just using a long block and putting the old fuel and ignition system in place on the new engine is my assumption. If this is the case you should be fine as long as all the bolt hole for your accessories line up.
