Default Air Boat Project

So I have another project starting to pile up. Still in the parts collecting stages but here's the plan. I have a aluminum hull already sheeted with UHMW on the bottom, I have a gear reduction unit 2:1 model and just scored a LS 6.0. Plan on using a stump puller 3 blade prop. Still need fuel cell, radiator, painless harness ect. So I am a ford guy by heart and those no changing that. But I'm also not to hard headed to make a smart choice. It's pretty well known that a guy can build a Chevy motor cheaper than almost any other due to aftermarket support and availability of parts. But I haven't done a LS swap before so bring on the input. If you done it in a airboat I want to hear about it. If you have done it in a truck I want to know what you did and what you might try different. Where to send my Computer to get it reworked to not need a tranny and all those little things. What sensors can I delete to simplify things and what sensors must stay. What RPMs should a 6.0 run at to spin the prop at the right speed and still be in the "power band" Any and all input is greatly appreciated

Should be able to get all that info on line. The LS swap is pretty popular.

I've had 3 air boats, but what you're doing is too deep for me. Go see Lenard at Alaska air boat. Up the parks on the right, just past the Holiday gas station.
I still have a radiator from my F-350 for sale.

Dan, An option would be to put a carb on it, probably cheaper than a wiring harness, reprogramming, etc and more remote location friendly to repair. That said, most EFI systems are pretty reliable. I think you will like the L series engines, tons of aftermarket support for them, and a very efficient design.

I sent my harness to the 12volt guy he has a website. you send your stock harness to him and tell him what you want to delete. Since im running a th400 i had him remove all the trans wiring besides the vss sensor. As for emmisions I had him remove all evap and egr related wiring and the two rear O2's.

He then makes it a stand alone, the motor will run off just the harness and has a obd2 and its on small fuse box.

I bought HP tuners vcm for my computer but I havnt had a chance to mess with learning how to tune yet. Good luck on the boat
