    Well, I almost had to buy another motor? Running hard on the street and bumped the shifter into neutral. I watched the tach rev b/w 5500 and 6000. I thought I was going to spin a bearing or watch a piston fly out of the hood. Did I mention this truck has a turbo? Yeah, when I let off it was hitting 4 PSI on the down slope. I ran the motor later on and it seemed to run fine. I guess I just got lucky! I know not to do that any more.

    Scary, nothing I hate more than a motor to free spin at 6000 rpms. I hate to say it, but I had an old Muuustang 67. I did the same thing with that motor on the track and was less fortunate. I had to rebuild. Did get a 13.5 out of it. 289 s are strong motors when built right. They rap up so fast, but not much on the top end. Anyway, the 6.0L is good as far as I can tell. Doesn't miss and idles smooth. I guess I was just lucky

    This isn&#39;t very good, the engine should have blown so you&#39;d have an excuse to build a built engine, LOL, jk, glad everything is ok&#33;

    To be honest, 6,000rpms isn&#39;t very high at all. When I had my 6.0L in my truck, I&#39;d hit the limiter very ofter at 7,000rpms towards the end when the trans would randomly slip on the topend end, never missed a beat. The yellow truck that is always getting stuff, has a high shift point as well, it&#39;s all stock. Another HD just left here with 10psi sts we setup and it shifts at 6,000rpms, still running strong.
    I bet these engines can take 7500rpms and not break. Ask vv8 hahahaha&#33; I&#39;d put money down on it that 8000rpms is possible, I don&#39;t know how many times, but at least once and live.

    Anyone want to try it out LOL?

    If I had blown it, I have my eye on a 6.0L out of an Esc. Caddy. A guy at work has one and is thinking of selling it to me. 345HP stock. It has less than 10,ooo mls on it. I bet Allen could really make this baby run. Maybe I&#39;ll put it in a old 69 Camaro or 60&#39;s stepside pickup. The possiblities are endless.

    Thanks,
