I was concerned the thread may be construed as a sales thread but really didn't know what I needed to know to decide what to do with the engine. My son has a very nice 67 notch survivor 273 2bbl, I was keeping everything in case he wanted to upgrade to some of the HP components but he finally decided it should stay as it is. He also has a 69 notch that we are heavily modifying for a Gen III 392. I'm going out of town for a few days, will think about the advice and probably make a decision by the time I return. Thanks again for all you thoughts and advice.
