*

I think I remember something like that from my Camaro days, but I can"t remember anymore. I know about the location near the distributor on the rear of the block, but I swear I remember there being another location down near the oil filter somewhere.I am setting the 283 up in my Bel Air to use the stock light, but I am want to hide a real oil pressure gauge somewhere in the car so I can be sure if what it is doing. I want to make sure that my memory is correct before I go any further.

I"m like you...I remember a connection point near the filter also. I think there may be a plug at the top of the filter housing but I may be wrong. I"m sure someone else will respond that knows for sure. Good question and I was thinking of doing the same.

On most 283 and small journal327 engines there is a oil pressure location at the front of the block right below the oil filler tube. Also one at the rear next to the dizzy. I dont know of one on the side of the block. Randall

Brian it may depend on the year of engine, but the 350 i have in my 57 has a place behind the intake and another place right above the oil filter. I am using both locations on my 57.Terry

Thanks for the replies everyone!Randall, turns out my 283 has that plug as well up front. I guess I"ll go ahead and use that one for the gauge and the one in the back for the stock sender.

I don"t know when they added the plugged port above the oil filter, but I"d guess it was the 68 or 69 models, which is when they went to the bigger journals on the crankshaft, the long water pumps, the accessory bolt holes on the heads, and a water temp sender port on the head. Anything earlier would not have that. Before then, they deleted the port on the front of the block. Beware, the port on the front of the block may show lower pressure than the one on the rear, since it has the pressure drop from the small passages plus the leakage loss from the lifters, cam bearings, and crankshaft bearings. This would show up especially at idle.There"s nothing wrong with a tee fitting on the port next to the distributor if you can fit it in there.That plug on the front of the block may be a bear to remove. Even the one above the oil filter. I don"t know what the factory used on those plugs, but it was nearly permanent.
