I had the same boat to 91 gps with me and a buddy in it with more throttle left. My engine made 711hp on the dyno. The X dimension on my boat was raised 3 1/2"s, all of the wood was replaced with coosa, and the cuddy was stripped so it quite a bit lighter than stock. The boat is running 75+ with a stock 502 mag now so the weight savings made a difference.
