Right! And, that engine is a monster for sure.

In GM's case, they are already starting out at a larger 6.2L, and the small block can go up to at least 7.0L, so it won't need as many revs. And, the LTx is now DI, which means you can go higher compression as well. |

Why do you guys keep getting stuck on a 7.0? You don't need an engine that size to make over 500hp n/a.

If anything, you will see smaller displacement in the years ahead.

just throwing it out there, I don't know enough CAFE and the regulations, but isn't it like a company average MPG that they have to meet?
Why is it that companies like Lamborghini make cars with only V10's and V12's that get an absolute max of about 20mpg? And were trying to figure out a V8 in a limited production car? wouldn't the mileage of both the V6 and I4 offset the impact of something large for the Z28? |

I was just playing devils advocate, as a lot of people in here make it sound like it would be super easy to do another 7.0 and have it make 550+ Quote:
I think some peopel have thrown CAFE out there, but it is more on the emissions standards IIRC |

As mentioned...most of the problem with the big-displacement V8 that Chevy says is tough to make has to do with startup emissions. |

People are hung up on 7.0L/427CI because that was the standard bearer in the GM world for N/A performance motors, and in general the NA market.
Motors in general are *expensive* to produce, certify, test, develop, etc...it's easy for the keyboard warriors to just say "hey just punch out the LT1 block, stroke it out, put a hotter cam in and BAM..550 HP!"...but they don't realize that it has to meet MPG requirements both within GM and trying to avoid a GG tax outside, has to meet long term durability standards, minimum warranty concerns, emissions, ease of manufacture, etc Just because a speed shop can do it for $10,000...doesn't mean an OEM can do that. What might cost a speed shop $10,000...might cost GM $10 million. |
