Dude, you have a lot of work ahead of you. Also, I have my doubts that the front MacPherson strut suspension on the 2000 can handle the weight of that 6.6 litre.

The Pontiac 403 engine makes a GREAT boat anchor. Other than that... not so much. If you want a "sleeper", then use a Chevy small block.

A sleeper is defined by the use of the new Vette 7.0L. 403? LELZ.

It would be a waste of time and money, Don't get me wrong, I love the 403's, but for what would be involved in a swap like that, it's a waste. You would be much better off finding another LS1 motor to put back in it, you'll never get the performance out of the 403 like you can an LS1 without robbing a bank.

It's a waste of time...NOTHING would bolt up not to mention you're not fitting that engine under the cowl. Look at another type of car, it's too much work for very minimal results. How exactly is building a Trans Am obtaining the "sleeper" image? The stock LS1 makes more power than the 403....
