www.fordfe.com Do a search on the forum. This is a work in progress by Wes Adams. The search function has been kinda funky there lately but you should get some hits. Lots of pics. It's based on a 390 block bored and sleeved with a 427+ size bore. Block has been hardblocked also. Interesting stuff. G.
