I gots "dial-up so it will be tomorrow before the picture will download. But, I will offer this two cents worth, if you change the oil regularly you dont need a filter, (they are nice to have-dont get me wrong -but not absolutely necessary), so dont fret if the plug is "out" and not plugging the passage, use detergent oil (which is about all you can find these days) and change it at say 2000-3000 miles oil change increments if it is daily driven-shorter intervals if "short tripped". We had a '54 pass car with no filter and non-detergent oil and tore it down (after installing a rebuilt 261)for curosity sake at 83000 mi (3.70 rear gear) and it had a half thou wear on rod journals with NO FILTER and original insert bearings. Them big old bearings have a light load on them as they were originally sized as a soft babbit material to hold up to heavy cast iron piston loads with low pressure lubrication. If I had another late 261 I would prefer it to NOT have to use the full flow filter or a bypass loop as the fittings and location of them are a royal pain to run exhaust around. Not to mention emer brake,clutch linkage, column shift mechanism,steering box, etc. just another object to dodge.
The old Chevy partsman that sold me the 261s, also raced 1/8th over 261s and said you just cant pull the plugs out and should just live with the pain of working around them. The plumbing looks like Power Steering hoses. Does anyone have any problems waiting for the oil pressure to fill up those huge lines and start showing pressure on the oil pressure gauge?
AH-HAH the picture came up-- I'd say the plug is not pressed in. Mine were clearly pushed in much more, it seemed that at least a quarter inch or more depth of the reamed hole was visible.
