I have had my car for 2 weeks now. It has the stock 5.0 and a five speed transmission. There has been a lot done to this car except to the motor. I was reading about ignition timing on these cars and read where the factory set the timing at 10 degrees. So, I get out my trusty timing light, unplug the spout wire, hook up #1 plug wire and crank her up. To my suprise, the timing was on 0 degrees! I have no idea why. I thought the car felt a little lacking as far as power. So I bumped it up to 14 degrees and filled the tank with 93 octane. HolySmoke! I have a new car now! lol. No pinging either! If you haven't checked and changed your timing from the factory settings, you are missing out on some free HP. Just saying!
