Might be pretty pricey but check out what Merc is doing with the LS. Ought to be a screamer.

They never mentioned what the heads cost.

So they showcasE their new marine engine in cars? WTF

Target price 27-30,000

This is somewhat old news. Merc will be coming out with a NA version of the twin turbo dohc motors. Gonna be between 800-900 hp, 7k redline. They just are trying to wait for the right time and figure out how to price it for the market. This is insider info I've been told from a very reputable source

On the LS front merc actually came out with that head a couple years ago. IMO..its worthless. everybody else has a solid marinized LS platform running up to around 600 hp. Hell you can buy a marinized supercharged LS straight from GM powertrain. In Merc's cute LS head setup its too much too late. You dont need those high dollar fancy schmancy heads to get good power from the LS platform, especially when for considerably less money you can already get marinized LS power in bravo eating range.

Here's 4 choices for LS marine power and thats not even counting Crusader...

Yeah just thought they were neat. Also not everyone wants to run a boosted engine. I figured if the price wasn't out of line a big inch ls with those heads would be a good combo.

You do realize your talking about Mercury right?? price, out of line, merc...lol, rofl, spit beer at screen, , chuckle, snort, blow out the hernia repair, pass a stone.... Merc, price out of line, surely you jest!!! And dont call me shirley...

I will tell you this much, who ever talked his boss at merc into letting him develop that, he gets the salesmen of the year award..

I do hope you realize this a satirical comment against merc, not you.....

Interesting, but stupid. Why not just Marinize a ford motor, or a Toyota, or a Nissan, or a merc, or a bmw, or a Porsche, or a Hyundai? There are literally a half dozen plus already designed large displacement V8s. Maybe they pulled an LT5 head print and figured out that they wouldn't have to change much.

For the heads or the whole engine?
