I have used Leon several times and he is very expensive. I think he is also really good and will use DPM again he builds carb or efi I have seen 1300+hp in house dyno huge new shop does drives too I think would trust him to work on any motor out there.

Derebery performance marine 235 highport rd. Pottsboro Tx. 75076 , and yes Leon is the man on building an engine, he builds some BIG POWER that last.

Leon replaced my 496's with vortech charged 540's, upgraded the out drives, blueprinted the bottom. Took the boat from 80mph to 110mph. They have been great to work with. He stands behind his work and will do exactly what he says.

Dmann, I have a truck going to Cleveland,OH on Tuesdays for the next few weeks...I will give you a call on Friday:)
