I have a 1971 225 3.7L odd fire V6 engine. I have a brand new Offenhauser intake manifold, it has two threaded ports, one at the rear just under the carb. and the other is in front just left of the thermostat. They both fit a bolt 1/2 20 thread. I would like to somehow use one of these ports for a temperature sending unit. Do you make something that will fit these size ports? or a adapter to reduce the size so I can find a temp. sending unit? Scratching my head……Chuck Thank You Or what do you suggest I try?
