I need to connect an aftermarket pressure gauge; I need a port to connect the sending unit other than the one by stock sending unit (next to the distributor) or the one next to the oil filter.
Do you know of any other ports?

Thanks,

 

Why not tee off the one by the dist, like the rest of us?

 

I have a superam and there is not clearance by the firewall, I should've done it when I had the engine out.

 

Post a pic of the area in question, maybe we can figure something out. I'm having trouble imagining how the SuperRam would keep a T from working, other than the obvious PITA of working around the SR while actually putting it in. The typical SR PITA situation unfortunately.

Should be as simple as taking out the whole factory fitting there, putting in about a 1/8" x 3" pipe nipple, a 1/8" pipe tee on top of that, and then put the OPSU where it would normally go and the other line in the other half of the tee.

 

I haven;t looked on a newer SBC, but older style (pre factory roller blocks) had a oil pressure hole in the front of the block, behind and to the pass? side of the water pump. Have to pop the hood on my Vette to locate it exactly, but might still be an option for you. Only thing I recall is it's 1/8thin NPT.

I think the issue you're having is accessibility to get it connected, once that big plenum is on?

 

The front main oil gallery plugs are indeed 1/8-27 NPT (brass plug):



There may also be a 1/4-18NPT plug above the oil filter boss (brass plug):
