LS6 in a Seaplane....awesome conversion.............. I was in Dallas 2 weeks ago at my annual Captain recurrent simulator training school, we met this other pilot that was in our class, he did this conversion. He said its a monster now with a ton of power. I think he said the factory engine had like 225 HP. It has a reduction gear transmission and a specially made set of headers/exhaust. It gets off the water in like 6 seconds now........
My question to him was about failing Crank Shaft Position sensors and failing Cam Shaft Position sensors....these cause the engine to shut down when they fail or act up. NOT good for an airplane........ He was wondering if theres a way to put dual sensors on the engine somehow for redundancy.....
He'll be chiming in here when he gets a chance......
Pretty nice set up though..........

One picture shows white zip ties, other picture shows black ones....maybe they are just holding something in place during the project.
There's 11 of these SeaBee LS6 conversions out there, this one I think is #12.........
Yea, I wonder if they replaced them with metal bands though, if they need bands at all for that.

I think he told me it only cruises under 3,000 rpm......can't remember.
When you deal with propellers you can't let the tips of the props go super-sonic or things will get ugly...lol......

If you like this. Go to geareddrives. Ls swaps for half a dozen airplanes or so. They just dont develop new aero angines like they do for cars. Thats why the ls engine is more powerful and more efficient than you stone old lycomings.

Check out WWW.Quietaviation.com Cessna 172 with LS motor there. Talk about a very interesting conversion. I did some interior work on this and the Owner of the company says on take off you have to climb out by "throttle feel" because the plane wants to "torque" over from the power out put.
. I guess I've spent too much time watching Bugs Bunny.

Always wanted to get my license for a single engine plane, but it just seemed like every other week or so I read about someone getting killed, crashing into a house or landing on a nearby street...lol. Its not a good excuse but it keeps my *** grounded.

Very Nice..
I would not think he could put any factory type of Redundant Crank sensor on, but he might be able to pin the balancer and put an external crank sensor on. CAM, Maybe change the front timing cover to allow a later model CAM Sensor in the Timing cover (this is a LS1 right ?).
I don't see any O2's or MAF on.. so I assume its a S/D tune !?
What would that black tube with hose be above the right side exhaust ?

The kit itself has been approved to sell already but, the plane is still in the experimental catagory so alot of FAA rules are out of the equation. Getting an STC approval takes hell and forever to get but, if you look at the site, Al Aden has quite the credentials and got it done quickly. Can't say enough about the LS platform.

An old GM engineer names Jim Rahm that helped design engines for cars...got into the aviation engine field. He builds a Twin Turbo Chevy Small Block for the Lancair IV-P kit plane. It beats an airliner from Miami to New York City. Seats 4 and its fully aerobatic. A/C and pressurized. IIRC, it does like 390 Kts at FL 290 (29,000 ft). It has a 5 bladed prop and they use a cockpit avionics package like full glass cockpit jet uses.
Its a beast......
