Angry Oil pressure sender location on small block

Where can I install the oil pressure sender on a 350 small block? This is one of the things I didn't think about prior to installing the motor. I usually install it just above the oil filter, but the allen head is stripped on the plug and it is almost impossible to get to with headers installed. After a couple of frustrating hours trying to get this $#@%$#@ plug out I gave up. I really don't want to pull this header again (another story). What are my choices? Below distributer? Any other locations?

Thanks.

Another port is located behind the distributor, right on top the main block rail (where the intake seals to the block), towards the drivers-side. This is the port used for cars with center console oil guages.
You'll have to take the distributor out to get to it.

That is what I did for my 93 K1500 (4.3, but essentially the same as a SBC) when the fitting broke trying to remove the bad OE sender. An autoparts store should have a selection of small brass fittings.

Re: Oil pressure sender location on small block

Hey guys, there is an 1/8" npt plug in the front of the block, in between the timing chain cover and the intake. Looks like an oil valley to me. It is even clearanced around it like it was made for the sender - it fits perfect. Any reason why I can't use this location? It sure would make life easier.

Re: Oil pressure sender location on small block

I believe that the only outlet on the ol chevy 350 blocks that will give you an accurate oil pressure reading is at the rear by the distributor but i could be wrong

Re: Oil pressure sender location on small block

One thing I left out is that this is a mid 80s truck block if that matters.

Re: Oil pressure sender location on small block

One thing I've noticed about that 1/8" plug at the front of the block-every 4 bolt main block I have ever owned has had that plug there. A couple of 2 bolt blocks I have owned did not have it.. Is this another indication of which blocks might be 4 bolt mains without tearing them down to find out?

Re: Oil pressure sender location on small block

I connect below the Dizzy port....I used a Tee one to the consol gauge, the other with pressure switch to the dash warning light.
I have the same for water temp using sensor by the water neck and the other in the head.
Its all very well having gauges, but if something goes wrong, there is nothing better than a RED STOP light come up on the dash also.
