That's awesome news!
I have a hypothetical question. If an LS2 were put on a dyno how much RWHP do you think it would have?

As soon as I have all info I will post to let everyone know.

Well, if we did, which I'm not saying we did, it would have made 360 RWHP, which is right in line with the best stock Z06 we have seen. The torque was about 30-40 RWTQ better then the current Z06 throughout the power band!! Of course, still not saying we dyno'd one.
I will say this, the electric door opening system is cool, no door handle inside or out, just a button. No key to start the car either, just a button.

Thats great to hear Brian.
I may be a customer of yours for the package. Have you guys thought about putting together a 408 or 428 package with the blocks?

The ls2 is not DOD, so it will use traditional lifters. The first DOD engines will be 5.3 to be but into trail blazers. Gen IV engines though use this revised oiling so DOD will work. The lifters are collapsible so when oil is turned off to that lifter the valve will not open. This is why the ls2 has external knock sensors.

Just to add to what John said, I think another reason for the relocated knock sensors is that the DOD engines use a different valley pan. The DOD valley pan has oil passages, etc. in it that are used to route high pressure oil down through the block to activate/deactivate lifters for those cylinders that are being brought online/offline.

In your opinion, is there anything that we haven't forseen that might cause problems with a retrofit into an F-body? And do you know if the LS2 knock sensors send the same level voltages as the LS1 knock modules, so the LS1 PCM could read them?

If the block can only be bored .010 to 4.01 then a 4" crank gives you 404 CI not 408, if you use a 3.9" crank you get 394. Of course now we have to wait for cams too. This is worse than the wait for AFR's.

Any new updates from sponsors?
I would like to purchase a fully assembled LS2 lunati stroker (4" stroke maybe 4.125" stroke) w/aftermarket heads & cam.
Seems like the delay will be aftermarket camshafts correct?
If any sponsors would like my business feel free to e-mail or PM me. Thanks!

I know you can get a very similar combo using the GM 6.0L Iron block however I did not do all the weight reduction just so I could drop an iron heap between my front skinnies.
I would buy a complete motor from GM (W/LS2 Heads) but my questions are regarding the cam and crank pos. sensors.
Are they located in the same place on the LS2 as they are on the LS1?
Can we get some verification in this thread on what parts are swappable between the LS1 and LS2?
Thanks.
