98 gt vs 03 gt block?

[AdamantiumKnot]

would it take much modifying to do that swap? i'm waiting to hear about my car being warrantied. i'm wondering if they'll put a new block in it.

The block should be the same.

I believe that the block is the same. The difference is in the pistons. If they use new pistions with your original heads, you will get a compression drop. If you get the PI Heads, you will be at 9.0 -9.4 to 1 compression.

what would the compression drop mean horsepower wise? would i lose hp?

yes, but it's safer for a power adder
