Im dropping this motor into a 1990 T-Bird Super Coupe. The cars OEM motor spun bearings and instead of having it machined, im going to go ahead and convert it for the 390. These cars weigh in around the 3800lb mark. Anyone heard of anyone doing something like this? I would like it to be in the 450HP area little less or a little more, while still retaining all the torque. Anyone have any tips on a conversion like this? What needs to be done?
