I have a 350 in running condition but ready for a overhaul. And a 400 that has sat for about 15years in the garage, and was "starting to smoke and leak a little" says the previous owner (Father). I'm considering rebulding one, so some questions I have are; Not bored or stroked, which would you prefer 350 or 400? What grit cylinder hone should I use? 60, 120, 180, 240 etc? Lifter valley oil baffles, opinions? Engine oil cooler? I have an Edelbrock Performer RPM intake, should I drill/tap for a rear coolant cross over? Phenolic or aluminum carb spacer? Block/heads? Orange? Flat black? That's all the questions I can think up right now. Any other ideas?
