asked that same question over at corvetteforum and the parts guy at Fitchner chevy told me they are not even sny prelims yet. GM won;t release them until they release the car I guess, so fall 2005 I am thinking. SUCKS!!!! I want the c6z06 calipers and those ls7 heads!!!!!

I was wondering if some of the parts made for our current LS1's, LS6's, or LS2's are direct swaps with the LS7. It is basically the same block just stroked out right? I was mostly curious as to whether i could get the 7.0 liter heads and golt them right onto my 01 T/A. And also I am thinking of getting a ZO6, whether or not a TNT wet kit for my T/A can be swapped to the new ZO6. The C6 ZO6 i mean. Are there any other parts that are interchangeable, well any other parts that are worth it?

Based on the earlier post (AFR 225 flow numbers), it looks like the LS7s will be worth the wait. I'm currently running Cartek Stage IV LS6 heads, and it doesn't appear that the AFR 225s will offer enough of an improvement to justify the expense of the swap.

LS7 heads will not work on 346. However if they did it would
be like in the Ford camp running a clevlead or yates head on a 302. It
will be outpowered by a smaller head until 6000 RPM....
LS7 heads will be beautiful for the big bore of 4.1 and greater.
Its pretty much a C5R head, and with heads like this the power numbers
will come up so that 600rwhp will be the new "bar".
500rwhp used to be the bar on the 408-434 stroker, now it looks like 550rwhp is.
