Ok first off I just replaced the head,cam, lifters,folowers and oil pump. Put in a new oil pressure gauge too. And the pressure at idle is 25psi it gos upto about 40psi at 3000 rpm. Isnt that a little on the low side? had to replace the head due to the last oil pump almost giving out. didnt hert the bottom end but the the head and the cam didnt like it so much. Anyone have any Idears on what to do? thanks for any help!
