Interesting spec with the nicasil bores.
What durability testing has been done on this?
There have been problems with nicasil bores on Jaguars and BMW engines before and Jag went back to steel liners.
Im guessing this is a track engine built for performance and not a street engine built for durability? Or am I guessing wrong?

And the price is?

We've ran 30 hour durability on the dyno and won Le Mans 6 times with similar bores. This block has been running for 2 years in C6RSs including track testing at Spring Mountain.

Right, it's built for track use, not street.

That's some high dollar **** right there...very cool stuff. I wish I had the cash flow to roll something like that under my car. Guess I'll just have to settle for your valve covers and belt tensioner instead

ALOT of $$$ FOR ONLY 700HP!! Sure is pretty though

LSX67RS/SS

if you have to ask, then you can't afford

Now that I think about it, we could have just bought a stock LS3 and slapped a Procharger on it. You're right.

Maybe we could do that for the C6.R too. Those cost $130k each and have only 580hp. I'll bring it up in the next staff meeting. Thanks.

If you guys decide to make the change to Prochargers with the Corvette racing program, I'll gladly buy one of the used engines you take out

Ok, I'll set one aside for you.

Forgive me if I don't hold my breath...

Let the internet haters hate. You guys make top quality stuff - you've proven that to me with the belt tensioner and the valve covers and coil relocation kit...I can only imagine what an entire engine would be like.

Just so we are all clear this is wheel power or crank?

Wasnt hating in any way just said it was alot of money.

Im sure hoping its wheel power. If so its even more badass, but still alot of money

It's from an engine dyno, not whp.

You have to understand who Katech builds engines for. These things have to last hours of continuous torture at high RPMs.
