So its like a 6.2l engine...???
The power per displacement is a little better than the RW HP numbers of the 4.0 VVTi...

oh ya jibby, dont knock RVs http://www.dynosources.com/
Pretty anticlimactic ending, considering all of the other corvette threads on the front page!Correct, it is 6.2 liters. I knew someone would do the math!
So, what is this mystery engine?
It is the BASE engine for the 2008 Corvette!!!
Rated at 436hp @ 5900rpm and 428tq @ 4600 and with the dyno shown looks like these numbers may be conservative as that only gives less than a 10% drivetrain loss.
This 2 valve/cyl pushrod engine makes more RWHP/RWTQ than the DOHC VVTi 1UZFE and 3UZFE and is externally smaller and comparable in weight.
Now, do not get me wrong, the xUZFE is a great engine and what I drive BUT hard not to be impressed with what can be done with 2 valves with pushrods. Did I mention it has an EPA highway fuel economy rating of 26mpg and avoids the gas guzzler tax.
I was ganna say vette, then I looked it up cause I didnt know the engine options (cause I though it was 6.2) and I found somethin like 7L.
Cool though.
Thats is a sports car motor though--big diff. Ok the size per power--thats great though.
How about IS350? Go down a little.

275hp / 3.5L = 78.57 hp/L Even the torque band is quite impressive on that car.
that's also the stock engine Gardner Douglass use for their cars.
they have LS2's and LS7's now. very expensive in this part of the world.
the debate about pushrods or not is not worth anything to me, if it works it works.
the LS7 in Steve's Lola T70 makes 630rwhp through a G50 box, and breathes through 8 kinsler throttle bodies + cam,
no boost no pistons no rods no nothing else. so their up to quite some more NA than what we're used to.
is that the LS9 version btw that everyone is talking about?

sillicon is added to the alloy so they're eutectic+ I might add,(whatsit called)
so a little stronger than what we're normally used to, I understand that the 2jzgtte pistons and maybe allso the other pistonds in that fammily aswell as 4age 20V pistons are also made like that.

ps those are the only engines I would sell my 1uz for, either an LS2 or an LS7. Now please don't shoot me..... if I had the money I would because of originality in a Lola not because of the engine itself.
That's a bold statement and is OK up to a point, but be wary if you are using high rpm and piston speeds, a cast piston will not hang together.Quality cast pistons are just as good as Forged....

Yes you are right.. But again there are some Forged pistons I wouldn't rev too high either.. The OLD TRW pistons are way too heavy.. Yes too many variations, in the end its cost and power - reliable power costs money !!!
Yes piston speed is an issue and so is weight. A cast piston is much different to a cast piston 10 or 20 years ago...Some Jap engines rev quite hard on std cast pistons...
