This must be possible less some slight computer mods?

This will change everything as far as modding the C5 goes!

Why supercharge or mod the LS1 and LS6 small blocks anymore?

Back in the day we all put 327's in to replace our 265's and 283's!

Cheap and effective GM factory parts work good, last long.

I see mint C5 Z06 engines going for $4000 or less.

So in a few years I can get the same power as the new C6 Z06 for cheap money?

Note: whoops! Should have said "LS7 Engine"in the title!

I think the idea is great.
But, I also think the swap will be quite involved. It will surely needs lots of rewiring along with extensive LS1 editing for the computer to operate properly. They you also have to consider whether or not you will want to retain the dry-sump oiling system or convert that over to a wet sump.
Bottom line: there are lots of big details to work out before this can become a reality. And it may take a long time for somebody to get all the answers needed for this swap to become a regular occurance amongst the tuners.

Exactly! Why? Now we can supercharge the LS7!

I will be happy with getting a 402 LS2 block in my car with the AFR 225's

You will blow the doors of a stock C6 Z06/7.

We just have to wait until someone works out the knock sensor issue - or just turn it off

Further, it will cost big money even if it could work.

How do you figure?
I can see that with the LS1/2/6, because people can upgrade to a C5R, but why would someone sell a 427 out of their C6 Z06? There is nothing to upgrade to.

Eh, 427's already cost big money anyway. If the crate engine, electronics, plumbing, intake, oil pan, pulleys and adapters (EVERYTHING) sold for $15K or less, it'd be a great deal.

Since Vipers have 500 cubic inches, I am thinking that people will want even more than 427. So they will build bigger blocks and sell their engines, just like they did with C5 Z06's after a few years.

That is what I am thinking, after a few years from now. There will be total wrecked cars' engines, crate engines, race spare engines etc. The cost of current used Z06 engines is quite reasonable, now that they have been out for a few years.

I am sure it will be a bolt in swap, mechanically at least. Andy at A&A already has a C5 427 in his C6, and he said it all fits, even headers come close to a bolt in.

Electronically, that engine is bound to run, even on C5 programming . The computer guru's will make it work, they can't help themselves from doing such great things anyway. There are stand alone LS1 engine modules, why not LS7?

427---here I come! In a few years!

I can't imagine the power though, I was out driving in 27 degree cold clear CT weather today and it was like driving on ice with the tire spin.

LS7 to a C5 should be a relatively easy swap.There are some minor details as knock sensors and tuning to be ironed out.

Hopefully the Guys at Scoggin Dickey will put together some packages for us - as they have the LS2.

My $.02.

Chris,

I attended the Performance Racing Industries Trade Show in Indianapolis last Saturday.

From 10:00 a.m. to Noon, Katech gave a technical discussion on the differences between the LS1/LS6 Gen III engines and the LS2 Gen IV engine.

The differences are great:

- The LS2 engine is set forward in the C6 compared to our engines and cars.
- The mounting holes on the side of the block for items such as AC compressors are different.
- The valley cover is very different in design function and physical size. Our LS6 intake manifold will run into interference.
- Sensor locations for such items as knock, MAP, etc. are different.
- The wiring for most of the sensors is different.

The list goes on.


Good luck with your decision.

Then all you'll need is a flack jacket to keep pieces of the C5 differential housing out of your A$$.
