I bought a 1964 thunderbird in major need of tlc and have been happy working on it an getting her in good shape. I will be rebuilding it's 390 V8. since i have it down to the block my question to the board is what should i replace with new parts. i am not trying to make a speed demon out of it but i do want it in very good working order. the engine on a whole was in good shape but with the years and miles on it a complete engine rebuild is kind of a do it now or later. i don't just want to throw another crate engine into it but i do not want to replace it with the same bad goods. let me know what y'all think. i could use the advice......thanks
