Ex Merc guys, we'll see how it goes.  Unless Intrepid has backers with deeeeeeep pockets, I'm not to certain...

Gimme a 400 Zuke, and I'll be happy...and that is very doable!

Bob What do you think the weight on that monster could be.

Around 1100.  And don't believe all the naysay about LUs.  Why come out with a 550+ motor if the LUs can't put the power to the water?  Mercs in this big time, just skunk work type business, if you know what I mean...

Just so much like THT - 8 pages and not one bit of useable info .....

You gotta admit they look deformed compared to what we are used to seeing.

Saw this interesting pic on THT.  As the poster states, the view of the headers suggest a horizontal orientation of the block...

$70,000 apeice?!?!
looks like GM LS based... probably LSA or LS3

70000$  might as well hang a vette of the back..

Looks like an LS3 with a modified Toronado-type gearbox/chaindrive under the block.  Not a very space-efficient or cost-efficient setup, but it avoids use of a dry sump, full pressure lubrication system that would be required if you tried to run that block in a vertical configuration.  The LS-3 has an alloy block that would help with weight, but that power transfer setup can't be lightweight...
