Retail on the Lunati 395 stroker kit for the LS1 is $3899.99
or...
Retail on a wet sleeved LS1 block bored to 4.110 is $2499.99
plus the $2000 rotating assembly.
or...
This kit is setup. Aluminum block weight, iron block price.
Money talks.

Also take in consideration the lighter weight LS2 block, no sleeving problems if a 402, reliability and excellent HP numbers. The LS2 stroker should be a no brainer especially when the knock sensor issue is figured out.

If you blew a hole in the LS2/402 piston or lifted the head, you would have done the same with your 427 wet sleeve block. It's the same internal parts. If your worried about burning pistons, get specific nitrous pistons. If your worried about lifting the heads, get ARP head studs and a set of o-ringed AFR's. The bottom line is, do you want to save $3000 bucks for 25 cubic inches. A properly built 402 will lay down killer numbers. Similar to what most 408 iron blocks put out. I've seen anywhere from 490-618 rwhp come out of 408's. It just depends on who does the heads and cam. The only thing you should worry about is getting the knock sensor thing figured out. If your going to be running that much spray, you'll want those sensors working.

I'm sure you could change the frequency range in the computer to the LS-2 frequency and use those sensors, but as of now, no one has done it.

The 6.0L LS2 is identical to the 6.0 Iron Block LQ4/9 from a performance perspective... here are the crank HP numbers from SLP's 402 and APE's 408... both are budget build. 402 is based on a stock bore... I am in the process of building up a 4XX LS2 stroker to go into my 2002 Z28... I have not yet ironed out the final details but it should be pretty interesting... There are quite a few LS2 articles on my webpage @ www.avigdor.net .

I might have to sell my 6.0L Iron block and jump to the LS2 down the road.
Why can't you just reuse your stock knock sensors and extend the wires? Did I miss something here, please explain...

The only warranty these will have is a 90 day craftsmanship parts only warranty. Please keep in mind we will leave no one in the dark! If there is a problem with the short block and it is for sure our fault, we will do everything we can to make sure you are taken care of. Worst case, we will ask that you ship the short block back to us for inspection, but I realy doubt we will EVER see any kind of problem. Our shop works very hard to turn out quality work, and inspects everything before assembly. Let me know if you have any questions!!
Everyone please keep in mind that I focused on price when puting this short block together. This is a VERY nice short block for the money and will handle alot of hp & will work well with most NOS aptications. It has very nice parts in it, but would not sugjest over a 150 shot (depending on your compression & tune), we are not limited to what I listed for the internals. If anyone wants to build a custom short or long block we can do it. I have Lunati, Callies, JE, just about anything you want I can get. Something else I just thought of, we have one or two 4.125 stroke Callies cranks on the shelf! 415ci with a 4.000 bore. This can be done but will cost a few more dollars. I just want everyone to know we have options.
Kris,
What are we looking at for turn around time from ordering to delivery, and how is payment going? Is it all up front or 50/50? Emission problems for CA guys with the 402? After discussing this type of build with you a few months back before the 402 option I couldn't wait, now I'm beside myself! I would like to have a little more time with Q & A when you get the chance. Please PM me for a good time to call or my email address. Thanks, and great job!
