I'm sorry to say that the only noticeable horse power gain you will get by boring it out .40 would be because of the new rings and pistons compared to the older used ones in it now...the 7 or 8 extra cubic inch isn't going to make that much difference. If you want the 307 to have more power...you would need to start at the heads and the the valve train, from the cam shaft up.
