Motor is a 3.3 dave bush piston and sleeve kit ported, rod slots done, etec front half stock reed cages with boysens. injection done in the front half,compresion on the motor is 120 motor has reved to 9200 so far. induction ignition
Adapter plate is modified
Motor is going on a Quatershot T3R with a 16 inch mid and a omc lower with 1:75 gear ratio boat is a little heavy at 500 lbs
Should be fun for a toy
Working on bumping compression to 180 for av gas, it should raise the torque and horse power
Motor is still be tested on the dyno
Dave is an awesome guy to work with i am very pleased to work with him and his friends

Dave is working on head for the motor, it should run about 135 to 140 on 1 set of chambers. The second set of head chambers will produce about 175 to 180 with the ability to run on av gas. With the increase in compression we are hopping to make between 440 and 450 Hp
I am in the process of building an open deck 3.3. with the hope of making 500 hp
Dave is giving great advice
Hope to have this motor ready for the fall, the work that Dave does always evolves into more hp he is in a league of his own. I hope i can keep up

will post some more pics soon and some dyno numbers
