I would like to know what seals gaskets and hoses and other parts I need to get while doing my 235 overhaul to keep it compatible with the ever rising amount of corn they are trying to shove in my tank and also keep it good to go with unleaded.

The main focus of this engine will be fuel economy and as much reliability as possible as its future is long hauls in an RV with some possible towing (popup or boat).

It has a carter BB updraft carb on it now as far as I can tell from reports on models used and a casual glance and no room to change from updraft (though sidedraft may be an option).

Please consider no tips too obvious as I am a serious newb with only maintenance experience on my modern vehicles by way of automotive expertise. The good news is I have all the time in the world to do this right.

You may find some pics here.
