GM powertrain engineers told the Car Craft/Hot Rod staff that some 2004 Vettes will have a 6.6L LS1 based engine. If this is really going to happen, knowing what the Bore & Stroke will be could seriously effect a persons engine building plans.
Ex. ~$1000 factory 6.6L block vs. $2100 resleeved block.
~$500 factory 6.6L crank vs. $2300 Lunati.

Any ideas on how GM is getting 6.6L?
4.0"x4.0", old style 4.125"x3.75" or something else?

That is one of the reasons I didn't go with an aluminum big bore block right now.

I hope they build it with a 4.125" bore because then I'll already have the 4.125" crank from iron block motor I'm getting built now. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

As it stands today, not all the components are interchangable! <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> You will not see this engine until the 2005 model year cars, which translates into the calender year of late 2004.

I hope so I would love to have something like that in my car. <img border="0" alt="[pimp]" title="" src="graemlins/gr_pimp.gif" />

6.6 Iron or Aluminum??

On a semi-side note, last year GM made a Silverado SS concept truck that had a 6.6 liter LS1 based engine in it. I assumed at the time that it was a standard 6 liter block stroked.

If the rumor is true, I just hope the new block or crank is a cheap alternative <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I read somewhere about 12 GM engineers being fired for leaking info on a ls1 ased "cam-less" engine that is supposedly due out around the same time....could it be the same.....
