496 replacement

Amm, Is it a 496 replacement because they are discontinuing the line or for some other reason? I am glad to see the GM offering this Gen3 LS line to the Marine industry. I have known them as a proven powerplants Off-Road since 1999-2000 and they keep improving. There is certainly a growing aftermarket for them and parts & accessories.

The Z06 is a 7.0L (427cid) naturally aspirated motor. 505HP
Yep. The Z06 is NOT a supercharged 6-litre. It's a very exotic titanium-rodded 427 small-block, normally-aspirated (fuel injected).

Pg 19 of this document references some GM memo. http://www.epa.gov/otaq/regs/nonroad/marinesi-equipld/a1998a-f.pdf

GM has announced that it will discontinue production of the 4.3L and 8.1L engine blocks in 2009. GM anticipates that it will offer a 4.1L engine block and a 6.0L supercharged engine block to the marine industry as replacements. Full run production of these new blocks is anticipated in mid to late 2009

LSA is actually the motor going into the new Caddy CTS-V. 550hp/tq

Major difference betwwen the this motor and the one going into the ZR1(637hp) is the LSA will have the smaller 1900TVS blower compared to the TVS 2300 going on the vette.

The LSA is supposed to find it's way into a higher end camaro as well.

It would be a sick little motor for a light boat:)devil

The LSA looks likes its going to have more hp than the Mercury Racing 525, yet being a replacement for the 496, the LSA should be priced closer to a 496. Yes?

We could only hope...Honestly with the TVS blower sitting on top I would say it cost more to make this motor by a decent amount than a 496. It will perform like a 525 (but be lighter) and it would be the perfect solution. I bet it's closer to the 525 price when all is said and done:(

It will also be stressed much more than a NA Merc 525. There's no replacement for displacement.

There is when they breath a whole lot better...the times they are a changin...


You're kidding right? When they breath better, huh? It takes a blower on the ls to match the NA Merc 525. So now, lets discuss breathing. I think your confussed.
