WIll depend on what cam you are going to run and what compression, etc. I would think with between 10:5 to 11:0 1 compression, and the right agressive street/strip cam, you should be able to make 525rwhp!

Have you tried doing a search? There are a half dozen posts just on the first page in this section of the board relating to this question. Results for these type motors w/L92 heads are just starting to posted. I am sure you can draw reasonable answers to your question by just doing a little reading and searching on the "L92" topic.
