It has been a long time since I posted here. I have a 283 sbc out of a 66 chevelle installed in my '57 Willys CJ5. It has been completely rebuilt to stock with 305 heads, Edelbrock performer intake and carb, stock oil pump and pan, stock cam. I did not want a highly modified engine since the jeep has such a short wheel base and I am running the stock T90 3 speed tranny with a Dana 18 T-case ( I figured a stock 283 would do just fine for a jeep designed for an F-head 4 cylinder). I have about 1300 miles on it. The oil pressure gauge reads around 20 psi at fast idle (maybe a little more) and around 12 psi at warm idle (700 rpm). When driving at around 2000-3500 rpm the pressure reads anywhere from 25-35 psi. Are these pressures OK? I did a search and could not find out anything on the normal pressure (numbers varied a lot). I just changed the oil tonight and put in Mobil 1 10w-30 synthetic (used Castrol GTX for the break in). I wanted to put in a Wix filter but couldn't find one locally so I used a K&N filter. I don't hear any knocking or grinding coming from the engine and it seems to run well (other than fine tuning the Edelbrock)

Thanks.
