The LT5 is not forgotten by Mercury Marine. Using the knowledge & experience gained during development & production of the LT5, Mercury now offers a modern version of the LT5 concept for automotive use. Mercury makes no bones about it...... The new automotive 4 cam 32 valve (a/k/a QC4V) engine is descended from the LT5!

Those new 1350hp and 1650hp DOHC race engines are wild.

Anybody want to guess how soon 4 of those show up in an unlimited pulling tractor?

Fond Du Lac, WI. Just a nice 180mi ride from Chicago. Maybe MM would be interested in a Heritage Day with the car that started it for them? Anybody know someone at MM?

Paul,

That was my thought. If they attribute their Performance line to the LT-5, maybe that would be a cool promotional thing for them. Sort of a homecoming thing. It would be neat trip we could do similar to what they did in Stillwater.

Any thoughts?

I wonder if the 1650 would fit in the place where
an LT5 belongs?

It would need space like the Falconer had for the V-12

...

In 1990, General Motors approached Mercury Marine to produce the all-aluminum, 5.7-liter LT-5 engine for the Chevrolet ZR-1 Corvette.

...

'90?

I thought that conversation started in '85?

The listed weight is tremendously high- maybe that includes the outdrive unit, but i think the engine itself is around 900 lbs last time i tried to figure it out. It's not gonna be in a car anytime soon. Also they are north of $150k ea. $400k for a twin engine drive system- The boat would be the cheapest part.

Of course the unasked question is..."Would it fit in a ZR-1??"

I think the question needs an answer... (I just said out loud what everyone is thinking!:p)

The BBC fits in the C4, remember BigDoggy? This engine is a 552 inch DOHC, TT Mercury produced engine.

Might need a power bulge hood for this engine in a C4. The 1650 requires 110octane race fuel, the 1350 does not. 7.8:1 compression on both.

These are Mercury Racing engines, 1 year limited on pleasure application, no warranty at all on the 1650 engine.

Length (in/mm)26.69/678 (from back of block)
Width (in/mm)34/864
Heiqht (in/mm) 29/737 (from crankshaft centerline)
Weight (lbs/kg) 1720/782

Warranty

1-year limited for recreational boating

Mercury lists the M8 drive as weighing 280 lbs, so that 9.0L DOHC engine is a heavy beast. 0-150mph in 13 seconds on the water is Miss Geico.

Yes it would.

Coil Near Plug or CNP on the LT5 revolves around the reluctor. Next time you get a custom LT5 crank cut, simply tell them to drop teh stock relcutor and cut a 24x (24 pulses per revolution) that looks exactly like this.
http://i1202.photobucket.com/albums/bb373/Paul_Schermerhorn/EFIConnection/021.jpg (http://s1202.photobucket.com/user/Paul_Schermerhorn/media/EFIConnection/021.jpg.html)

You can get thee xact same patter by paying $20 and ordering
12552480 for the 24x reluctor and around $80 for the crank sensor - 10456248.

You can do this in a snap because custom cranks are so cheap and easy, and the integration with the LT%'s ECM is so simple.(sarc)

That car must "turn on" really good. I'd sure like to take a spin in that beast, and I'd really like to take a peek at that calibration.
That fuel system looks BEEFY. Thanks for the pics.

Looks a lot like the prototype Gen II LT5 plenum, except for the dual TB's instead of the single large one:

the engine without turbos, ecm..etc.. is $68,000. weights 600 lbs without turbos etc.. 900 fully loaded up. 1600 hp. I wouldnt mind that. if it doesnt fit, then it will be made to fit. we can just leave the clam shell hood off the car and make a carbon fiber cover to just cover the engine. quad came lives on!!
