Default 5.3 cam and compression question

I got my 5.3 today, I have two cams, a custom grind that is 224 duration and lift is 589/609 with 110 lobe seperation, my main question is, with the bore and stroke of this engine being smaller then a 5.7 will this cam be too big, it was going for a stock 5.7 with 241 heads and ls6 intake, but since I got rid of that car and my new one has a trashed block, i am debating on selling and buying a different if this is too large, also what is the stock compression of a 5.3 l33 which is what I have.

See that is where I am confused, I have seen 9.4 and 9.9 compression for the 5.3 l33. Thank you for clarifying the stroke is the same.
