GM Small Blocks: LS9 & LSA
These are two pretty stout small blocks. Is there a marine version of either of these engines.
The Generation IV LS9 is 376 cu.in, 9.1:1 pistons, 638 hp (ZR1 motor)
The LSA is the same just detuned. 556 hp (CTS-V motor)
What would be the cost if there is a marinized version? Nice stuff.

Small blocks are great , I have the 6.2 MX [ 377 ] blocks and happy with it.
The LSA would be my choice if I built a project .http://www.gm.com/experience/technol...LS3_Marine.pdf
You could also get these from Kodiak engineering for a few years now http://www.kemequipment.com/superchargedvortec6000.html

The LS9 S/C is making more than 133 hp compared to the LS7 with 51 less cu.in. and 9.1:1 pistons. The LS7 N/A has 11.1:1 pistons (505 hp). The Eaton blower seems to make the LS9 a nice engine.
Back to my original question on cost of LS9 in a marine application, is it available, cost? The LS7 does seem like the way to go.

I was supposed to get a pair of these for my 29 Baja last winter. The deal fell through.
I think it would have been a cool project. The swap would have lost me 1000 lbs out of the butt of my boat.

I realize I have lots of questions, but I would think if the motor is marinized, then, with the headers in the market place for this motor that the cam shaft profile would be taken in account. I am not well versed in small aftermarket exhaust on this block design though I have been following the SBC thread for older style small blocks (exhaust location differs).
