I do not know what to do. My 350 runs like a champ never whimpers or whines, but is obviously tired and old. All the smog stuff has bit the dust, vaccum tubes are god only knows. The carb is a mess. The motor mounts are broken I am at the limit of my basic tune up knowledge. I am planning a few long drives, moving and it will become my day driver. the engine has well over 200,000 on it and i fear that it might bite the big one. Should I rebuild, by a new crate, or tuff it out and put new intake/carb type stuff on it? i can not do any of the major work myself( appartment/no garage/time/knowlege/tools) I thought one of you might wana jump in and guide me before i let a mechanic have at it.
