Reply to "High oil pressure"

First, where is your sender connected? If its at the back of a 351-C block, that's high unless the engine is stone cold. If the sender is over the fuel pump mount like a Windsor or some aftermarket blocks, it may be 'normal' at hot idle. Certainly it will be different. And we're all assuming a std, not a high pressure/hi volume pump, which is never needed on street (or most race) cars.
