new corvette engine

Post by Bdriller » Sat Aug 13, 2016 10:09 am

while searching for a ls motor for a new boat build I ran up on a 2016 NA corvette motor with 3 miles on it for a ridiculous low price includes all hardware, computer and harness anybody know any down sides to this engine came out in 2014, so far all I see is no power steering bracket. Also I have selected a ls6 with 243 heads going with edelbrock carb and msd need cam recommendations.

Honestly I would lean toward a mass performance engine. Not mocking that engine I would rather a purpose built engine that is made for my application. In the long run you will be much happier.

The Gen V LS motors look really cool. The stock LT1 makes 460 HSP and is direct injected. The problem with the Gen V motors is that the aftermarket isn't that strong. This makes it harder to get parts and the parts are more expensive. Personally I am waiting on an aftermarket EFI for the Gen V to come out from Holley or FAST before I give one a shot. 8)

So I saw a DB rigged boat getting pulled back to the ramp 3 months ago with a brand new 416 CI MAST motor. :stirpot: :stirpot: :stirpot: :stirpot: :stirpot: Don't know what was wrong, but they pulled it 8 miles back to the ramp. :shock:

Also there are more stock components in these "purpose built for airboats" motors than most people realize. The LSA motors are all stock except for the tune. For engines under 700 HSP, nearly all of the engines from WT, MAST, TKE, etc. are using the following stock parts:

1. Engine Block
2. The stock crank will definitely survive in an airboat. Most builders recommend upgrading the pistons and rods along with ARP rod bots.
3. Heads (with double springs and trunnion kit; also the stock LS3/L92 heads flow 317 CFMs)
4. Lifters
5. Rockers
6. Oil Plan (my WT 418 came with a Gen IV truck pan)
7. Intake Manifold
8. Coil Packs
9. Front, Rear, and Valve Covers

And you don't have to take my word on this. Go look at the websites for WT and TKE. Also there is a ton of info on the web on this topic. Given how well stock LS components do in an airboat, why would anybody want to run an A/C motor. :stirpot: :stirpot: :stirpot: :stirpot: :stirpot: :stirpot: :stirpot: :stirpot: :stirpot:

@ blow boat - Not that it effects the point you are making, but just so you are aware . . .
There are MAS Performance engines and there are MAST Motorsports engines.
They are two different outfits. When people use the names interchangeably it only creates confusion.

@ CarMotorBarge - You make a very good point about 'purpose built' vs 'purpose tuning'. That is all good information and could save someone a lot of time researching before they jumped in that end of the pool. I will watch for your indication that such a Gen V EFI has become available. On a similar but different note, when comparing such similar later model apples, should one just simply seek out the one that produces the most HP at WFOT, or should the associated torque curve possibly be given some kind of consideration? :)

Going to the 2014 Gen V LS may be like taking on an EcoTech build. They have a lot of technology that may prove a challenge in an airboat application.

1) Active Fuel Management - direct injection turning cylinders off and on

2) VVT

Note: Compression 11.5 : 1 with a new piston design could be risky.

All good points I think its to soon for the new corvette engine need to let the after market catch up, and glad mas,mass, mast, has been cleared up, I recently met keith from MAS performance hell of a nice very informed fellow, based on his knowledge and theyre warranty I would recomend them.

I was just giving a good example of a good engine for an air boat I never said they were the only ones. :slap:

Who cares whether it is HSP or torque that turns the prop. 8) As long as you got a car motor and it turns more prop than an A/C motor or an EcoTurd, you are good to go. :stirpot: :stirpot: :stirpot:

The compression ratio doesn't scare me. The new motors coming out keep increasing the compression and making more torque. Would like to see the torque curve on a Gen V motor with a few aftermarket upgrades. 8) Give the aftermarket time and they will get it figured out. Just think 20 years in the future everybody will be talking about how the Gen V motors are obsolete technology.

That's right, "If", you can turn more prop than a ecoturd....:). I like how you put that JR!

Note quite like an Scotch but not far off LOL.

Kolby and the crew at TKE has had the Gen V engines running stand alone for a good 6 months already. They've worked with the GM COPO program and even done a LT 418ci with 2.3L blower...very impressive but Kolby still wants to do another 6 months of hammering these things on and off the dyno before he'll offer them with a warranty out the door. Not bad business, and I can't wait to have a 418/427 LT motor on one of my boats. :D :D :D
