what is the proper oil pressure readings for a 3800 s/c engine (stock) at idle and and at higher rpms, im reading at a cold start 40 to 45 psi idling and revving it up some im getting over 50 psi. damn kit only gave me 5 feet of tubing to work with so all i could do was a hook it up and see what im getting, ill need a longer tubing kit to get to the A-pillar, unless there is someplace else i can tap into to get oil pressure readings closer to the driver side of the engine bay, any thoughts? thanks Scott
