    With those heads and cam you are on the right track in my opinion to make that.

    900 shouldn't be any problem, I built a similar 540 that made 900 with 2 750s

    I remember that motor. I pieced together all my parts and took them to my engine builder so if it doesn't make that it's on me. My builder thinks it will make mid 800's but I think it will be 910-925. I'm going to guess 914. Find out in a couple of weeks!

    I wasn't going to say anything but 14.3 should make a thousand easy.

    Not all dyno's are created equal.
