Wow thats allot of material swinging , yes the next thing is hd gimbles .

Here are some pictures of my exhaust rings. This is how FPM did them. I'm a little concerned because there is no tolerance..very tight fit..no room for vibration movement..I'm worried my headers might crack...Anyone experience this and could give me some advice?

hope
 

Hope you have lots of spare stuff on the transom and props.

thanks for all the help on the exhaust rings . i took them off and had about a 1/4 of an inch taken off the original bore, which is something that should have been done in the first place.

Ran the boat on the 4th..it totally surprised me...got on plane like if it was on rails...2500 rpm on the 2 outers and 2000rpm on the center and it jumped right on plane..
Results:

3000 rpm- 55 mph trim- 2 tab- 0
4100 rpm- 78 mph trim- 3 tab- 0
4600 rpm- 88 mph trim- 3.5 tab- 0

Boat handled totally different..i felt a little of steering torque..it carried the bow beautifully. Had wife with me on the boat..she said she didn't notice any difference on the handling..but I could tell that it had to be driven over 88mph.. and I was afraid to push it any more without a professional driver with me. So I am taking it down to Rolf Papke in New Jersey ..he is a professional racer and he is going to dial it in with me..will post results next week...

Ran the boat yesterday in New Jersey..Ran great..not as good as I expected it to..
I ran 108mph @ 5800rpm....98 @5200rpm....I think there is still more left in it. I was hoping to break 110mph..taking some diameter off the outer props and see what that will do.

Wow! That's flying!!

thanks for the reply .it does feel good when you can cruise around at 4500 rpm at 85 mph . it looks like every body else here on this forum has swallowed their tongue but they will find out what i all ready know .

I only hope your drives can take it , otherwise thats great news .

Have you got your spacers yet?
