We have a customer that completed one of our 402 short blocks with a set of Lingenfelter CNC ported LS6 heads (65.5cc) & a GM grand cup cam, compression is about 10.8. I believe it made somerwere around 570hp & around 515 ft lbs of torque. He was using the LS6 intake and a ported tb.

The dyno was done on an engine dyno. Last time we talked he said he was going to fax me a copy of this dyno. I will follow up & find a way to post it.
Wanted to let everyone know that I found out that the LS2 block uses it's own lifter guide. The lifters are the same just the shape of the guide is a little different.

I spoke with Kris today, and he said they have even come up with a solution for the knock sensor problem, to allow using the LS1 knock sensors. 
Looks like I'm gonna be ordering an LS2 402 before the week is out!
I'll probably upgrade the crank and rods though - I can see a turbo kit in the future as well.

It's hard to see in this picture but look just above the end cylinders and you can see it. I will try to find a better picture.

Post some pics and dyno #s on the LS2 mag when you get a chance.

Kris, how much for just the block, front cover, timming set and valley cover for those of us who wish to build it ourselves? Also, what condition does the block come in, meaning what machine work is required? Align hone the mains, final honing the bores, and the balance? Thanks for all the help. This is great news about the knock sensors.
