Gasp, the chambers were the same across all the open chamber LA heads, and the 360 gets miserable mileage in my opinion. Look at a newer non hemi 360 truck, they are like 8/12 MPG real world numbers. Lots of people say the 360 pulls like a big block, I say it drinks like a big block. But hey, its only gas and im building one even bigger so what can I say? Look at a Feather Duster or Dart Lite and its specs. Now thats an efficient motor. and its still a 225 six. I think a carb rebuild is the first thing to try, not a rebuilt carb, but a carb rebuild..get it? You can do better than a rebuild service 99% of the time as your stock carb has all the correct pieces for that model, and your model specs are in the carb kit documentation..not parts from a cleaned set of parts bins put together to make a complete carb. Get yourself a kit, some Berrymans, a caliper and some carb cleaner in a can and get in there and spruce it up and put it back IN spec. Second best thing to do is to get an electronic distributor, and then basic tune up stuff. If you can do it outside on a bench, better as youll have better light and some ventilation. Both chemicals stink and seem to linger far longer than your job.
