Oil Pressure issues on new motor...
 

The gauge fluctuates from 0-30psi erratically. I am breaking in my new 331 and I know it is full of oil and runs very strong.
I think it is the old pressure sender that is the problem, the wire came into contact with the header off of number 5.
Does anyone have/know/recommend a mechanical pressure sender that I can install directly into the cockpit?
I need precise oil pressure measurements as I plan on installing a vortech as soon as break in is complete.
Thanks in advance...

When you put a "mechanical" gauge in there are two types.
1. Copper/plastic line going directly to gauge
2. Same as above

r and r'd the sender and viola! even with the "crappy" gauge, it is reading 60+ psi under hard acceleration and 30 psi at idle.
don't think it's so bad, of course it is brand new. we'll see in a few months I guess.

I put a mechanical autometer guage in a cage on the dash. just ran braided line from the end of the extender tube on the old factory location. Seems to work perfect. :)

ALL of my gauges are mechanical. Just don't trust the electrical sender units/gauges to monitor my VITAL engine stats. Oil pressure drops, and in the back of your mind you think "Did I lose oil? Or is it a wire, or sender unit?" NOPE. Just not worth it. I have waaaaay too much B/S/T in my engine to be worrying about that kinda crap. Go mechanical, and be done with it.

Yeah, I wanted to keep a clean cockpit and not have gauges here and there. But I guess it's time to look at gauge pods. I agree, I have too much invested to guess at stock gauge accuracy.

Look into that 2 gage center vent cage. Found mine at summit. it is made by autometer. Seems to good quality and I think they give a nice look..

will do, it doesn't completely close off the vent does it? I like the sound of something flush.

My buddy has the automeeter mechanicals in his 90 with a 408. It is the dual cage that goes in the vents, and it does not totally block the vent. Very nice, if I do a fox body, I will be using that set-up.
