WILL the motor ever be used in a Corvette again and why didn’t GM supercharge to 427. CHEERS EVERYONE!

I highly doubt it, but you can never say never. I would think that GM thought that the 505 hp rating was good enough and besides they had the ZR1. But I can tell you that a Z06 with the Callaway package did have more HP then the ZR1.

The LS7 had very weak walls between the cylinders,{they wanted too keep it a small block} that's why it's wasn't used for supercharging

Due to ever stricter emission and fuel economy requirements I doubt we'll ever see a large displacement NA engine again. Much easier to meet the emissions and fuel economy requirements with a smaller displacement engine using forced induction that still makes plenty of power.

They better not **** up the valve guides again if they do.

It's unlikely. GM has realized that people will buy a poorly engineered supercharged engine just as easily as a much more expensive to design and build large displacement NA engine.

Z28 Camaro and 427 Vert C6s will be collector items one day.

Unfortunately we will never see an LS-7 again. With all the technology now you can squeeze more HP out of smaller lightweight platforms. The 427 will become a legend in Corvette lore never to be seen again.

id bet the next 7.0/427 will be back in the c8/zora/L88 mid engine car

What is it about the supercharged engine that is poor?

Whether the world ever sees the engine back in production again, I am grateful to have driven mine for as long as I did.

hotrod03

Me too

The LT4 has pretty well known cooling issues, and isn't really anything special. Where the LS7 and LS9 were really well developed engines with lots of race tech, the LT4 is basically an LT1 with a blower thrown on it. It's cheap and easy to do for GM, and the buyers don't really seem to care. And I mean, it's fast as hell too, so that doesn't hurt.

I have owned several C-2 427 Corvettes. there is nothing like the sound and torque of a 427 big block Chevy in a Corvette. Add a helping of side exhausts and is is unimaginable unless you have experienced it.

I would bet dimes to dollars you will never see a 7L ever again.

Direct injection and FI will ensure that.

hotrod03

Yep your probably right for sure!!

beat me to it. Thats how we got the LS9.......

No. It hasn't appeared in 40 or so years. It was gone forever back then. The real 427 was a big block. The recent '427' was a fakey doo punched small block badge engineered to appeal to oldsters who wished a real 427 in their youth but were unable to buy one then.

It's not only dead but pointless.

They still need to correct the issues with direst injection causing the intake valves to gum up. Toyota is experimenting with dual system that injects at the intake ports as well as directly into the cylinders to help keep the valves clean. That is one reason why I don't like the C7 among others. It's a shame to see the 7.0 liter go but with major screw ups like valve guide problems that were never addressed or fixed Chevy shot themselves in the foot on sales on that engine. As we know news like that flies thoughout the car community. I love the C6 ZO6 but I didin't want to spend an extra two grand to prevent a major problem that should not occur in the first place.

I would really like to know why GM didn’t take responsibility for the LS7 issue. Who and why? Was it just about money, when they were in Chapter 11? GM really let us down and it really angers me. What would the GM CEO do in he purchased a product that failed?
Would I have not bought my 427 vert if I had to do it over again?? In a heart beat I would buy it still. I had an L88, my choice, LS7 hands down!!
