Cant forget that raising the engine, you will have to cut angle and reweld pipes to go out of the same holes.

I love that grey paint...Reminds me of the playboy Cigs.

Tres,
Thanks for all the great info! However, still not sure boxes are worth the money. You also did bottom work to the boats you added boxes to. How much speed was attributed to the addition of the boxes vs. the bluprinting of the haul? I've heard a good bottom blueprint job will add 5 MPH.
