i just did an engine swap to a 408 stroker motor everything is good but the idle. i was wondering if anyone knows how i can run the car with a good idle for now without tuning.

good idle on a stock tune with a 408 isn't going to happen. what you can do to crutch it for now is open the tb blade more to bring the idle rpms up. you may also have to drill the bypass hole larger.

He's right. I personally would not drill the bypass hole. Find a way to keep the TB blade open a bit more. Get to a tuner.
