I have a 97 cougar with a 4.6 that has crapped, is it feasible to install a 5.0 or 5.8 without a lot of expense and problems? The car only has 50,000 miles on it and is in real good shape.

i like the idea of the mark VIII DOHC swap myself i'm hoping to get started on mine this spring as long as i get a good deal on the motor.

It is possible, but it is a lot of work and not really worth it. The cheapest and easiest thing to do would be to get an 02+ explorer 4.6 and swap it in. That is an all aluminum PI motor and between the extra 40 or so hp and the weight you lose off the front end, and the fact that it is a direct bolt-in replacement for the engine you have now, it is probably your best bet.

^^^ what he said. 5.0/5.8 seems out of the question without expenses and challenges to overcome.

5.0 or 5.8 is a good option if you had a 3.8l because that uses the same tranny bolt pattern and mates up.
The 4.6's pattern is totally different.

Or I can always sell you a 5.0 with trans for $300 plus shipping.
