ls1 intake swap Ok i have 5.3 in my `67 chevy ll all stock tune only emissions part tuned off of computer.I just got ls1 intake with no injectors/rails.I`m wanting to use the ls1 intake with the 5.3 rails and injectors and throttle body,seems it would keep the swap easier. The injector wiring on harness and fuel/return line would hook back up.My question is would i need to get my computer retuned with the new intake being the only difference?Thanks for any help or suggestions.

You could bet by with your present tune, but thats the least of your issues.
The truck injectors and rails will not work on the LS1 intake, without a bunch of work. It would bea lot less work to change the plugs. If you have the 4 point steam vent pipe, there is a good posiability that it will not fit under the intake. If you're running the truck accessories, you need to relocate the idler puller at the alternator and most likely will need to use a differant belt
