I just sold a full 4EFTE with everything attached for £550. Awesome condition engine with only 67k kms on the clocks iirc (will have to check the clocks as I can't remember, but it was low mileage). I've previously sold a good condition engine for £300, without anything attached. And this week I am buying a 5E block for £100 (just the bottom end to forge). If you want a bare 4E block to get the ball rolling, give me a shout. I've got a few here.
