Let's clear a few things up - Your car a 3rd Gen. Is the "350" you put in the car an LT1 engine?

From the sound of your other very hard to comprehend post, you swapped in a Gen 1 "350". Hence questions on the setup need to be posted on the correct forum.

I already moved your first post about the engine problem from "Drivetrain" (where it didn't belong) to "3rd Gen/L98 Tech". You have to post things on the correct forum, or you are never going to get any answers.

I'll move this one to the correct forum too.... but you need to try and post things in the right place.
