LS9 vs LSA

[ZED SLED]

As long as we're all still just guessing, I'll go out on a limb and say the Z28, if it ever does happen, will be track car with a 5.5 like is the Corvette.R used in the American LeMans Series.

But if they build it, I doubt that it would be called Z28 - though I'm sure that moniker will be revived sometime in the future...

I doubt they'd be able to move 5000 of them at the price they'd need, given the fact that there would be a 550+ hp ZL1 available for around $50,000. Could they sell 500? Maybe, but then the price would have to go up again. They would have to go through all the testing and validation that they've done for the ZL1 again in order to bring it to market. And for what? If you want 600+ hp you can easily get that out of an LSA. If you're afraid of reaching the limits on the LSA, you could build up a motor of your choice and swap it in for less than the premium of the LS9 super Camaro + mods to get it to the power point you want.

The GT500KR is a GT500 thats been upgraded by Shelby, not a special production car off the Mustang assembly line. I put it in the same class as the cars you can get from Hennessey, Lingenfelter, SLP, and the others NOT what you can get from GM at a regular Chevy showroom.

I wonder if the heads from the ls9 will bolt up to the LSA? If so would this bring any kind of power increase or do you think that you would lose so reliability?

edit: and would you have to do anything to the cam or would the stock LSA cam hold up?

It will hold up but what a lot of the guys with the cts-v were doing is swapping the LSA cam for an LS9 cam, which show some pretty good gains with virtually no effect of driveability

I've heard that to. As for modding the engines, I highly doubt the LSA would be able to take what the LS9 can with its forged internals. I've heard of a few guys that have blown up their LSA's on the CTS-V boards, but have yet to hear of anybody blowing up an LS9

Likely the majority of forum members won't be racing enough to really tell the difference. The ZL1 will be so high tech performance designed that the only real place you might tell the difference would be in a highly technical timing event. But, not on the street IMHO.

Each engine, for their power rating, is just as reliable and the LSA is even a tad more efficient. So it really depends what your definition of better is. If better to you is more powerful then yes LS9 is better than LSA, but the LSA is still a damn good engine.

Oh without a doubt it's better!
First of all they are essentially the same engine. It's just. That they take the LS9 further up the ladder

Now I can see why they call the LSA model as ZL1 and not Z28. They are saving that next bigger version against what Ford will be coming out.

....hmmmmm,....the plot thickens! I like the sound of that rumor....

I like the sound of them selling the ZL1 for $1 ... doesn't make it any more likely to happen though

What kind of gains are they seeing just doing the ls9 cam swap? I mean is it really worth the money spent to do it?

hell, I'll buy one in each color, plus verts...

probably easier to do a pulley swap for more gain

Hell i hope they put the ls9 cam in it from the factory or at least something similar. Is 100 crank hp increase possible with just a pulley swap?

I had this explained to me recently by Spike. It all depends on what you want. the worth of engine doesn't get 'better' just because the numbers and letters get higher.
