Was planning to do an electronic ignition swap per Slant Six Dan. Then fired it up this morning and found that an old weld, just forward of the carb on the exhaust manifold there was a huge crack at a point that was welded before. trying to decide what's next. i want to make this a reliable daily driver and as it seems im into this at least as far as pulling the intake and exhaust im wondering what recommendations the group has. I can put a little money into it but not a ton. I'm just looking to make the most of the down time and the opportunity to make a few improvements. Considering a better exhaust, and maybe a different intake/carb setup if this will make for an improvement. Also considering a turbo in the future? Whats the consensus for reliable daily driver setup for max performance and mileage?
