oil pressure
Got a 77 400 motor that runs strung and smooth but when I first start it it runs high oil pressure. When I drive it for about 20 min and come to a stop the pressure goes away! can anyone give me some advice on what could be the problem? Thanks in advance!

hmm... i got about the same issue here. I installed a pressure gauge in mine. when i first start it it says about 60psi at idle, after about 15-20 mins of driving i stop at a red light and it will say about 10-15 psi. but while driving about 20-30 psi doing 35mph in 4th gear. is this normal? as far as i know the engine has never been rebuilt. run 10w40 in it.
