LS7 Crate Motors... already being delivered - $11,000!!!
...and it's only $14,000...
http://www.gmpartsdirect.com/results...partnumber=LS7
Where else can you buy an aluminium V8 427ci hi-po dry-sump motor for $14,000??
It just get's better and better...
It won'y be long before you will see C5 retro-fit kits for the motor.
Looks like my C5 Z06 will be around for a long time...

^^^^
so Rc, you wont be going for the 383 stroker after all?
last year, you seemed quite convinced that 500-550 crank hp would be more then enough to handle and still be streetable...
is it actually cheaper to buy a brand new LS7 then to build up a $6,000 LS6? or is it the dry sump system that gets you?

Well - with $6000, 500rwhp, 346ci Heads/Cam option it is very hard to not go that route.
But the pure carnal nastyness of 427ci cannot be denied. And 427ci based LSx motors require a lot of work - even C5R block based buildout require a lot of work.
If the LS7 proves to be pretty reliable, then how can you argue with a prepackaged 427ci solution?

well an oem 427 for 14,000 doesnt exactly seem the deal of the century, when compared to the offerings of the LS6... but If reliability isnt the issue these first car seem to be having, then not so terrible.

Tuner 427's with the appropriate components ran $15, $16, $20K - so $14K and dropping is a good starting point
Besides, a 500rwhp 346ci motor is working hard... a 500rwhp 427ci motor is relaxing

$14k for a handbuilt 427ci easily making 500hp.. sounds like a deal to me. I am eager to see just how reliable the LS7 will be.
Will definately be interesting to see what kind of monsters tuners an hot rodders will make with this engine..
If I had a ridiculous amount of money and the know how, I would figure out a way to shoe horn this beast into my RAV4..

^^Look at the Le Mans, the only reason the C6R won is because of reliability. GM doesn't seem to have reliability issues, it's just the lack of quality materials put on top of the reliable drivetrain.

I'm fully aware of the reliability of the C6R, and even though the C6 z06 is developed straight from the C6R, both cars are built for different purposes. The engine of a C6R will never see the type of mileage Z06 owners would hope to get from their engines..
I am personally biased towards Japanese manufactures such as Toyota (my family has only bought toyotas because of their amazing reliability and low price value) because you can treat the engine like shit and it will still run for 100,000+ miles..

So talking about all these conversions.. any details about a possible swap into a 1.25 Ford Fiesta?

Well i've seen careless drivers beat on their LS1 powered car without chaning the oil for 10k miles. It was slower than it should have been but still ran despite the face that LS1's are known for oil lubrication problems. I recall more issues with the E46 M3 engine then the LS line of engines.

gms small blocks do that easily as well. They are generally known as bullet proof.
Its not uncommon to find 350 l98s from the 80s with 200000 miles still running close to the same 1/4 times they did when new.. And thats the 80s version, we've had 25 more years of research.
How do I know about the l98? I raced and open tracked one with a stock engine other then wires(all suspension mods, though expensive ones) about 2 years ago that was from 1988. I drug it out to the drag strip before I installed the suspension and matched the time car and driver ran in the 1/4 in 1988. After 15 years and 100000+ miles the only problems with the car were electrical/rusted out exhaust.

the average mileage on japanese cars and trucks up here up is about 270-350 before they start having serious problems.
of course you have your exceptions.
you'll see some high mileage domestics as well but not nearly as many (and as good running) as their toyota and honda counter parts.
.normally i wouldn't consider an engine reliable if it can't run for at least 250 before needing some major work done.

A high performance engine like that out of a vette used for track use that has 100-200k miles is a bit different then the honda you drove to work for 10 years. I saw speeds of 140 on this stock engine, and Im sure the previous owner didnt baby it(who does that to a performance car).
I always wonder when I hear about honda and toyotas car reliability. How much are they aided by making cars that arent performance related. If you dont run the piss out of it, reliability certainly will be better, even with lack of routine maintenance. The nsx and supra not withstanding(which Ive never seen 250k mile examples of) neither company has made a performance car long enough to reach 250k miles.

Not a bad plan RC especially considering you can resell your original motor.

The biggest difference one will notice between a 505HP LS6 and an LS7, is tha the LS7 will have a much flater tq curve, and the LS7 is a dry sump hehe.
