The C7 Corvette is coming! Are you as excited as we are? Our friends at General Motors/Chevrolet have taken the social media outlets by storm with their #one13thirteen ad campaign. The C7 Corvette will be unclothed from its camo coverings on January 13th, 2013 to a sold out group of National Corvette Museum supporters and a limited group of journalists and industry insiders.

Last week Chevrolet unveiled the newly designed C7 logo at Petit LeMans with much fanfare. Here at the National Corvette Museum we offer C7 Lapel Pins (now sold out), C7 Logo Bricks and our smartphone C7 wallpaper ready for our Corvette faithful to purchase or download. Today Chevrolet has released information on the heart of the C7 Corvette, dubbed the LT1.

LT1 first was introduced in 1970 to the Chevrolet lineup and was an option on the Corvette from 1970 to 1972. Between 1970 and 1972 just shy of 5000 cars were produced with the LT1 engine with the solid lifters. The 1970 Corvettes packed the most punch with 370hp, and General Motors started detuning the engines to give oil companies some time to phase in lower octane levels for unleaded fuels needed for the future use of catalytic converters. 1971 LT1 Corvettes suffered a decrease to 330hp and the final year of the 1972 LT1 was at a meek 255hp.

The C4 Corvette in 1992 reintroduced the RPO Code LT1 as their base engine packing 300hp at 5,000 rpm and 330 lb-ft torque at 4,000 rpm. One big achievement for the LT1 was the introduction of the reverse cooling system. Traditional cooling methods route coolant through the water pump first then through the block to the heads. The LT1 engine routed coolant to start at the heads and then down through the block. This kept the heads cooler which allowed for greater power.

excellent. 11:5 compression !

6.2 liters 450/450. So much for the 5.5 liter theories.

Just saw that too!!!!

Here is another thread on it.... Click Here

I can see a turbo version in the top of the line Vettes what ever it may be....... With direct injection they can really handle boost!!

Sounds like it might be fun

Only 450?

450/450 sweet

dupe...but if we must

Preliminary numbers suggest no less than 450 horsepower and 450 pound-feet of torque.

This is really really great news! Before I feared the C7 engine would be downsized due to the relentless onslaught of gov regulations. Now it looks like the 427 may still be in play.

Hopefully active fuel management can be turned off though, even if the new Vette is likely rated at 20mpg city & 30mpg + highway with it on.

And for some disappointed by 450hp, remember that's still 20 more from the same 6600rpm fuel cutoff. So I think the much bigger complaint, is the extra $5,000 added to the sticker.

Base engine.

450 > 430 > 400.

Never-Enough

I'm aware of that. I just think that is a bit low with the current HP wars. Especially since this is GM's flagship car.

450/450 is enough to shred tires with the best of them.............

If you want power you have to buy a Camaro

In 1971 the LT1 suffered about 40 hp drop due to lower compression 11:1 to 9:1 and emissions. In 1972, the hp ratings changed from gross (330hp) to net (255hp) which only lowered the hp rating, but the performance was about the same. I had a 1972 Z28 with an LT1 engine which was the second fewest Z28's (2575 units) next to 1967 Z28 (602 units). Nice to see the LT1 is back into production.

I had active fuel management or AFM in my 09' G8 GT. (L76 engine) it sucks!! Any aftermarket exhaust will make your Vette sound like a sewing machine at idle and low speed. Glad I bought my GS when I did because IMO the C6 is the best Vette ever!!

450hp can't shred cheese in comparison to todays market! You have a ZL1 with 580, a Viper making 640, hell even the six cylinder 4.0 Porsche is making 500hp. We can go on and on, don't forget the Mustang!! 450 is an embarrassment IMO.

Interesting point, never thought about it from an aftermarket exhaust standpoint.

I have never driven a car with cylinder de-activation, so I have no clue how seamless it is. That would be the biggest concern of mine, especially in a high performance car like the Corvette.

If the activation isn't immediate then it will be a serious performance hindering nightmare.

I honestly don't think that cylinder de-activation belongs in a sports car.

Never-Enough

The C7 is supposed to be revolutionary & they give it a whopping 20 more HP? Same old GM.
