Picked up 1961 235 today. The engine is complete. Previous owner removed from 61 Car to put in V8. Pulled plugs, put oil in cylinders and turned engine by hand for about a dozen revolutions, put 12 volts to starter and 12 volt coil with resistor, gas to carb. Fired on first turn. Idled good, restarted several times. No pipe on exhaust manifold but could not hear any strange noise. Tomorrow I want to check oil pressure. There was no oil filter on the engine so where do I hook up the oil pressure line??? There are two plugs on the drivers side. One is at the rear of the block, the other is about midway just above the pan rail.
Also I notice what looks like a plug on the passenger side just ahead of the two bolts that holds the coil, is this an external oil passage to tap onto for an oil pressure gauge?
