GOT THE HEADERS ON THERE!!! THANKS TOM... AFTER BREAKING IN THE CAM THEY WILL BE SENT OFF FOR CERAMIC COATING INSIDE AND OUT.

ITS A BUMMER THAT I HAVE TO POST THIS... THOUGHT THE BOAT WOULD HIT THE WATER FINALLY, BUT WHEN I FINALLY GOT THE ENGINE ASSEMBLED AND STARTED I FOUND WATER GETTING INTO THE OIL... AFTER DISASSEMBLING THE ENGINE I FOUND A CRACK IN THE CYLINDER BLOCK FROM A PREVIOUSLY BROKEN CAMSHAFT... TIME TO START OVER

I have a 454BBC 4-bolt main Gen V block if ya want it.

GOT A SECOND BLOCK THAT WE FOUND A CRACK IN THE CYLINDER WALL AFTER BORING IT .100 OVER... I HAVE BEEN TOLD THAT A MARINE BLOCK HAS THICKER CYLINDER WALLS AND CAN TAKE THE .100 OVER BORE.  IF ANYONE HAS A MARINE BLOCK LET ME KNOW.

LUCKILY THE MACHINE SHOP IS TAKING CARE OF ALL THIS AND HE WAS VERY CLEAR THAT WE WERE GOING TO BE DOING THIS AND IF WE FOUND ANY SIGNS OF DAMAGE THEN MY MONEY WILL BE RETURNED.  I AGREE WITH YOU AND I HAD HIM CHECK IT FOR CRACKS AND WHAT NOT... BUT HE TOLD ME THAT WHEN BORING BLOCKS THAT MUCH THAT SOMETIMES THEY CAN CHECK OUT FINE AND THEN WHEN YOU BORE THEM YOU GET A LITTLE PIN HOLE OR HAIRLINE CRACK THAT WASN'T LEAKING BEFORE YOU BORED IT OUT SO MUCH.

AT THIS POINT RIGHT NOW I'M DREADING HAVING TO DROP A COUPLE GRAND ON A DART BLOCK BUT THINK I JUST MIGHT HAVE TO... ESPECIALLY SINCE I'VE HEARD MOST PEOPLE SAY NO SUCH THING ON THE THICKER BLOCKS... I'M NOT FINDING ANYTHING THAT DIFFERENT FROM WHAT YOUR SAYING EITHER.

MY ONLY OTHER OPTION IS TO GO A LITTLE SMALLER... ANYONE WANT TO BUY BRAND NEW .100 OVER PISTONS? I WAS TOLD BY THE MACHINE SHOP THAT THEY ARE REALLY NICE PISTONS AND THE RINGS ARE STILL GOOD TO GO... MAKE AN OFFER AND I'LL SEE IF I CAN JUST BUY SMALLER PISTONS AND NOT BORE IT .100 OVER

you can always start with pulling the inspection cover on your pump and looking over the impellor, but it sounds like you may be overhauling this pump.

ITS A BRAND NEW PUMP FROM TOM AT JET BOAT PERFORMANCE... HAS MAYBE A TOTAL OF 6 HOURS ON THE PUMP

You need to call Tom and JBP and tell him what is happening.

OK SO ONE MORE THING TO ADD ABOUT MY SHUDDER OR VIBRATION @ 60 MPH

I TOOK MY BROTHER FOR A RIDE AND HE WAS THE PREVIOUS OWNER BEFORE THE BOAT WAS RIPPED APART AND REBUILT.

HE TOLD ME THAT IT USED TO SHUDDER A LOT MORE EVEN AT LOWER SPEEDS... HE SAID THAT WHEN WE TOOK THE HOOK OUT OF THE BOAT AND ADDED THE RIDE PLATE THAT IT WAS SUPPOSED TO HELP AND HE SAID IT FEELS A LOT BETTER AND WHAT I'M FEELING IS THE BOAT COMING OUT OF THE WATER AND ONLY RIDING ON THE RIDE PLATE WHERE IT IS SKIPPING ACROSS THE WATER... ANY TRUTH TO THIS?  I ALWAYS THOUGHT THE BOAT SHOULD GET SMOOTH WHEN IT IS OUT OF THE WATER AND ONLY RIDING ON THE JET...
