Just for some added information:
I rebuild my engine entirely instead of just throwing another one in and couldn't be happier. It's balanced perfectly, has 9.5:1 compression with forged pistons, is slightly over-bored (not sure if that did a whole lot, though), and has been trouble-free for 6 months so far.
Price-wise it's cheaper to throw a L36 block into the car, but if you want to rebuild it and have a good quality machine shop to take it to, go for it!
