Graham Goode used to knock out brand new crate engines both 2wd and 4x4 for around £3800 plus vat
Brodie Britain had a few inc RS500 ones but probably all gone now
Last time I checked Ford still had big turbo escos engines for 10.5k plus vat
but a few years ago they had a clear out and sold 10 new engines for £1500 each

I read it in a Ford trade mag I receive, went straight to my dealers on the Monday morning at 7.30 am they rang the disribution centre and all 10 had sold minutes before.
