oil pressure
 

I have a Coast High 347 stroker with clevite bearings, childs and Albert rings, probe forged pistons, a steel crank, and a main girdle. I have about 30K miles on the motor and had ntrous for about 15k and a Vortech T trim 10# boost for about 5K. I use 10/30 oil and teflon additve and change every 3K. Lately my oil pressure drops below half after the engine is fully warmed up and never returns to it's previous 3/4 postion.

I was wondering if the oil pump may be going bad or what else could be causing the pressure drop? Please toss out any ideas that will give me peace of mind. I don't really push the motor but would like to once in a while dust of a Vette or two.

Thanks ya'll

What are the numbers?

did you use the old sending unit from the old motor? These fail and the time and give low readings, just replaced mine on a 92 convertible, it was doing the same thing, go to pep boys and get one, while you are replacing it ,screw a manual guage in first to get an accurate reading, I have heard of many early 347 kits in need of a rebuild before 50k........
