Good thread, I have 2 - 575's with Whipple low rise coolers 3" pulley. At 200 hrs, I had the top half gone through, everything, except the head gaskets, was in good shape. At 300 hrs, I had a leak down test performed and I had one cylinder at 9% with the remaining cylinders 5-7%. I now have 325hrs and I feel its time to go through the top ends again. My question is, with that many hrs on the engines, should I just just go through and keep stock or add some up grades?

I had the original prototype and it is still working great 6 years later. I no longer own the boat, but speak to current owner fairly often. I also ended up at 760 hp before I sold it and this setup fueled it just fine. Get ahold of Eddie, he can fix you up
