Question... would a Chevy 1800 engine fit in a Opel Astra?

The Astra is really more of a highway cruiser rather than a speed demon... you really can't make much to make it win stop light races... :P However, once you're on a highway, i'm sure you'll feel better at 160kph vs. the lowered Civic/Lancer/Corolla/Sentra next to you. ;)
