I have been lagging on the pictures, but not the work. I measured and made models of the tail pipes. These were then sent to IMCO to build them. Dave and Air at IMCO are very helpful with this process. I am changing the exhaust tips to 4.5" so my exhaust will be dry all the way to the tips. I have also finished all the plumbing of all the hoses. I have installed the hood and made the cut for the blower to clear. I am now working on what type of scoop or vent I am going to use.
The tail pipes were sent to me yesterday so I might here her rumble this weekend. I will get some more pics in the next few days.

Mitch:
Great rigging and workmanship as usual! Like that trick of using pvc pipe sections and elbows for the exhaust tip mockup.
couple of suggestions though. One, have the header tip outlet water put in the lower vertical drop section of the tip, pointing out straight towards the tip opening out the back of the boat. this will keep all the exhaust water routing out the tip where it belongs, not backing up in the engine at idle and such.
Two, I am not so sure its a good idea to have that oil filter pointed straight out the front, right next to the belts. I guess if you lost a belt you would probably be shutting down pretty quick, but the oil mess would be a job to clean up after the belt tore into the filter.
Just a couple of thoughts and suggestions here.
Great Job, can't wait to hear how that puppy flys!
Best Regards,
Ray @ Raylar

Thanks Ray. That is the only place the filter can go. In a 22ft boat I am trying to put 10 gallons of sh$t in a 5 gallon bucket. The rear of the motor is full and I did not like the remote mount. I am a little worried about the belt deal, but I have only broken one on my old motor due to the rear seat flexing into the belt. This engine has way more clearance in the front than the 496.

Bjorn, I am using my stock mounts that came from Eliminator. As small as my boat is it wont see any offshore time. I am not sure when you need to go to the offshore style mount. Maybe some one will chime in.

Thanks fellas. I will post some pore pics after the weekend. As far as how it should run, I have my estimates. 496HO stock 425hp 28 Bravo labbed = 80MPH. Whippled and Raylared 496HO 655hp 32 Bravo labbed = 100mph. 4.0 Whippled 540 955hp = ? Any guesses?
I now have a 1:36 IMCO shorty. I had a 1:50 Sportmaster shorty. I hpe to keep using my 32 or 34 labbed bravo's.
