390 oil pressure
By Tim Hartford - 09/07/2003 9:27:19 PM; IP 204.60.226.118
It seems there have been a few questions about 390 oil pressure. Just had the 390 in my 64 t-bird rebuilt. All new parts (seals, rings, bearings, etc). The mechanic installed an RV cam to boost the power. The engine now shows very low oil pressure at idle on the stock guage. Starts out about middle of guage and then drops to just above low mark (in the safe zone) when warm. Increases somewhat with higher RPMs. Currently running 15-50 weight synthetic oil. Oil pump is new stock type. Before rebuild, this same engine tended to have very low oil pressure, but now is worse. Put alot of money into rebuild and don't want to "blow it" ! Any help is greatly appreciated.
