I am helping a friend out getting a chevy powered rod going.
This could be the simplest answer in the world.
Old engine 305 had oil pressure take off at the top just behind the inlet manifold, where most of the Ones I have seen are taken from.
On the new motor that take off has been bunged up and is not coming out.
Correct me if I am wrong but there is also a threaded hole near the oil filter, is this an oil gallery and if so can I run the oil pressure switch from here, if yes,
The thread is bigger than the one at the inlet manifold!
Question 1 can I take oil pressure from here?
Question 2 what size is the thread?
Question 3 what size is the thread on the take of near the inlet so I can get a adapter from one to the other!
Thanks for any help
