That was a short run for the LS2. Watch for them this Fall.

Same as the vortec max but with l98 block?

[qwik1320]

Great - keep going GM. I figure they'll be at the LS5/9 by the time I get my car done...500hp and 30mpg if you please!

[WS6]

Fine by mean. Hopefully LS2 prices will start to drop now that the LS3 is coming out.

[Ralph LoGrasso]

Anyone know if we can get a stroker 427 out of one of these?

[chicane67]

This has been around awhile over on the Corvette Forum. There was/is alot of interesting scuttle about the LS3 and what its all about.

[trapin]

I doubt you'll see LS2 prices drop anytime soon. That's still a killer engine. I know that LS1 crate prices through the dealers have since held steady.

[boodlefoof]

Anybody know what the differences are other than displacement?

[craig]

i think its the L92 6.2 thats already out in the k trucks with a diffrent rpo. oh and of course diffrent intake, cam, software etc.

[Goatman]

The truck block is probably iron, while the Vette one will be aluminum. Just like the LQ9/LQ4 vs the LS2 now.

You can get the same power out of the 6L motors with a little work and at least at first, you'll save a whole bunch of $. You know those things are gonna bring all kinds of money the first few years..

[WS6]

My bet is that it will be nothing but a punched out LS2 with the L92 heads that are already on the trucks. However, it would be great to see some sort of in between LS6 L92 head. I doubt it though.

This is the motor that the Corvette SS should have minus the blower of course.

[craig]

the truck l92 6.2 is aluminum block!!!!

[Goatman]

Wow. That's pretty cool then. Someone might be able to score one at a decent price if the guys at the boneyard think it's "just a truck motor"...

But, we'll see!

With a 4 inch stroke crank the L92 guys are getting to 415-416 CI. I'm pretty sure that this LS3 should be the same.

[craig]

with a 4 inch stroke and 30 overbore its a 427. cooollll

If it is at all like the LS1,LS2, or LS6 block it will only be able to be honed. I think the most that could be taken out was .01. Even if you could take it .03 over it would still only be a 420. The stock bore is 4.06 with a 4 inch stroke that is 414 CI. 4.09 with a 4 inch stroke equals 420 CI. I'd be cooler if it did end up being a 427 though.

[Goatman]

Its just a number..... And no one is going to know if you just lie! It makes no difference whether you have a 400, 427, or 418! As long as you make power.


And you'll have to do the very expensive re-sleeve just like the LS1 guys do if you want a big bore motor.

[BLT2DRIVE]

L92 Is Out As a Crate Now. I Saw It At Pantera In Costa Mesa Getting A Going Over(custom Pcm ,intake Stacks) For A Dyno Run. Nick At Pantera Said 620 Easy. Stock With Their Intake And Pcm. Cam I'm Not Sure, It' Been A While. Pantera (949)250-1797
