Hello friends. Was wondering if I could get some help. Recently had a 68 FE390 in my Fairlane 500 fastback rebuilt. The engine only has about 50 miles on it. I took it up to the local gas station this evening and noticed it is beginning to smoke out the exhaust. When I got home I let the car idle and noticed it was still smoking out the exhaust and when I opened the hood the engine at the intake manifold fill tube/breather as well as the pcv valve when I briefly removed it was putting out smoke as well. My oil pressure was between 60-80psi. Water temp steady at 185. This motor has a high performance cam with solid lifters, Weiand aluminum intake and Edelbrock 650cfm carb. I'm just wondering if I should be giving this engine more time to break in or if there is seriously something wrong going on. I'm not famiiar with Ford FE big blocks and was not sure how to proceed with this. I know the engine was bored .060 over and had new pistons, rings, cam and crank bearings, heads serviced. Thank you so much in advance for any help you kind folks could offer. I'm very worried that the engine needs to come back out and broke down.
