[LX5liter]

Was it an eight cylinder car before? If not then a bigger rear end, (8.8 or 9 inch), front springs, and brakes to start, then a different drive shaft, motor mounts, shifter, hood may not fit anymore, possibly the brake booster, (although the 86 & up boosters I think will fit, I just went to a manual setup). Thats just a start, I'm sure you will get lots of replies of thing I have forgotten about. Is it worth it? To a point it is, you can't beat the torque of a big block, but it can be a lot of work.
