I changed my plug wires today and wanted to see the top speed performance. I got up to 125 mph on a Texas staight away. Everything seemed OK. I slowed down, turned around, gunned it and it got up to 70 fine, then it wouldn't go over 90. I slowed down and kicked it in again, and again nothing over 90. I then slowed down by coasting and heard a little rattle while slowing down. It got to about 65 and I pressed the gas a little to keep the speed. I heard some more rattling. My oil pressure was fine and the water temp was fine. I shut the car down, put it in nuetral, and coasted to a stop. I put it in park and started it again and it was making an aweful racket. It was a HARD KNOCK and also LOUD HIGH PITCHED NOISE. I called roadside assistance and got her towed back to the Auto Hobby Shop at my Air Force Base and one of the guys that work there think it's coming from the top of the engine, like from a SC bearing. But, my friend thinks it's a rod bearing knock.
With what I described here, what do you guys think? I'm sweating it here, and wishing I weren't SO FREAKIN' CURIOUS about top speed (which I still didn't get to, it still had some in it but my friend told me "OK, that's fast enough!!!!!). I never went into redline the whole time. At 125 it was only about 4000 RPMs. Please help with any advise.
