That's one of the years that may use stretch bolts. I ran into this problem with my Euro motor when it tried to torque it like the normal 2v motors. I wrecked a couple studs. I ended up torqueing it like the 5 liter. I torqued it to a value then 1/4 turn then another 1/4 turn , something like that. You have to find out if you have the old 4.7 studs or the ones like the 4 cams. Maybe someone on here knows how to tell.
