I am here to draw upon the wealth of mechanical knowledge on this forum to help diagnose my brothers chevelle. I don't know much about that type of engine.
I believe the engine is a 400ci that has been destroked to 377ci. It recently started flattening the spark plug gaps. He doesn't think the rods have stretched because they are supposedly high quality. It doesn't sound like the crankshaft is moving around or anything. He's a mechanic, neither he, his boss, nor anybody else he's asked has been able to figure it out. |

Is the transmission an automatic?
On some of the older 3 speed automatics there is a vacuum line connected to the transmission. It is possible to pull transmission fluid into the engine through this line if the modulator fails. |
