I have never heard of them until I saw a video on YouTube can't say good or bad but I would go with Mast for a LS engine they were recommended buy another engine building company this company told me they make the best cylinder heads out there

Mast is a good choice but put your money down and buy a Waterthunder. You won't go wrong. The engines are built from the crank up to be used in an airboat. Dave has put tens of thousands of hours into his designs and they work. If I had it to do over, I would have gone that route.

Thanks for the reply!

If I was to order one from him it would be one of his 500 cubic inch LS motors with mast 305 heads on it and the XR composite intake

Going from a DD 350 on a glass boat I would expect a slight performance improvement

That is very true 👍 but I will say I was only speaking of what I would do and not what someone else should do post a video of it running on the boat like to see how it does on the water

You made a good choice, I bought a motor from Dave two years ago put it on a 15 foot Hamant, great motor.

For Ls go with Dave at water thunder. Money best spend. I have over 150 hours on my motor I bought this spring. Not one issue.
I was that guy doing the same thing. So glad I went with his motor. pushes my Alaska airboat everywhere I point it and sips the fuel with 87octane Image
