I've been trying to order a Turner 4.6 for over a year, but I guess they have some virus problem or something like that holding them up.... I've been told to stay away from AB and Cannibal, and the few reputable local boys are out 3-6 months before they can touch the project. I'm not tracking any NOS long blocks anywhere. TWS seem to have a solid reputation and can have the long block to me in 3-8 weeks.
My 4.0 finally died at 200K, and other than puking every fluid out within minutes of fill, most likely has a slipped liner(s). Build will include flanged liners, warm cam, worked heads + oversize valves, Mark Adam's computer magic, shortened intakes, etc. I'd love to be able to merge and keep speed on our western hills AND keep it all Rover. I do plan on a RRC fan and 4/5 row radiator to help in the cooling department.
Any tips from the pros?
