4mulafastech, Thanks! dry the boat is 4700. It is balsa core and vacuum bagged. They also did the deck a little lighter to save more weight. the boxes were the best thing I ever did. The boat already handled great (like a 28 saber) but the boxes made it perfect. It always flies level and drives through waves. Anyone who has ridden in it can't believe it is a 27' (27' 3" not including the mini platform) I also picked up about 8-10mph with the drives raised 3". I think there is a little more in it if I raise the X a little more. I made my boxes with neutral, +1, +2, +3. It is on +3. The boat had a pretty conservative X. I know the 38 formulas love boxes! All you can do is try them...some gain mph and some lose, so it is expensive if it does not work.
Pullmytrigger, 355's, balanced, decked, ported iron eagle heads, 6" H beam rods, 10:1, 750 mech carbs, roller cams, 36 deg timing. 6100 rpm. The motors are pretty light since they have the bare minimum.
ToMorrow44, good to see another advantage! Boat looks great! Love that motor! Don't you have a box on it?
