Glad it all worked out.
I do not agree though on the subject of maxing out the gauge.
There should be a "peg" or stop of some kind that just allows the rheostat in the sender to give a max voltage equalling the 80psi no matter how much pressure it senses (within limits) that way if you had thick
oil on a cold day and exceeded the 80 psi it wouldn't damage the gauge's sending unit. Kind of like on some gauges they have a simple "peg" that keeps the gauge within its physical limits.
Speaking of limits its kind of like the Rev limiter. They are nice to have.
Just an opinion. Lets keep the "good ideas" like this thread coming. We can all learn a LOT from each others experience.
On a different subject. My son brought his 66 Big block Corvette over yesterday to check an
oil leak. (Valve cover) He just had a new FRAME put under the car with a lot of "underneath" work done while it was off. I lifted the hood on the 427 and couldn't believe the physical size of the motor. I'm so used to the V6 in the Cobra that it seems "normal" to me now. We both were laughing about the Cobra having 83 more horsepower. He whined "a little"
He's now "plotting" nitrous but it won't "save" him
