Ford Racing 427 burning oil

[68pony]

Gday all
First time poster, I have just fitted a brand new 427 crate engine(M-6007-Z427FFT) from ford racing to my 68 mustang, i know its not a cobra but i'm sure some of you guys have used this engine and maybe you guys can help,from the first start up once it got to norm temp it would smoke out the exhaust, its definatly oil ive done 300 miles now and no better, it only does it at hot idle, no smoke when cold but as engine warms up it starts to smoke( blue smoke) once you take off it does not smoke and as soon as you stop and start to idle its stinks and smokes, i don't know alot about engines and just wondering if anyone has had any issues with these crate engines, are the intake gaskets that come with the motor any good, my mechanic is adament its not leaking from the inlet manifold and doesn't want to pull it off ,its a super victor manifold which has been ceramic coated , he is saying the motor is a dud, i don't agree, can someone give me any ideas, you can actually wipe the oil from the tail pipes with your fingers it has probably used half a quart in 300 miles any help would be appreciated , i shipped the motor direct from the usa to here in sydney
cheers chris.
