My neighbor has a jet boat..recently purchased with rebuilt 454 (motor has about 5 hours on it) with original 1978 block..Edlebrock almn. heads. Mild build single Holley. He has an electric oil guage that always reads 80 lbs. even after motor is warm. We thought it might be the guage or sending unit so we tried a mechanical guage...same reading. Using 30 WT. oil..Has a 10 qt pan and running 8 qts..had 10 in and took 2 out just to see if it would change..stays at 80 lbs at idle or WOT..What is the possible problem or what can happen if you run pressure this high all the time..
