I DO have a 2010 V6 Camaro. I drive an equal amount of hwy/city driving, and avg 20mpg, with a semi-heavy foot and the a/c on. The motor has had ZERO problems and is very reliable. That being said, there is no way I would put it in my 1973 Corvette. You cannot make it sound very good...because it's a 3.6l. I have an exhaust on mine, and it's, well, ok. About 2% as good sounding as my Corvette! Also, the 278rwhp and 231rwtq I don't think would be as exciting as you think in these cars. Best of luck!

I have a twin turbo V6 in my BMW putting out 300 HP and even though it's fun to drive and a very responsive and fast engine I would never put it in my Vette. Just saying.....

I have a V12 in my BMW putting out over 300HP... and I DID put it in my Vette...(Build-http://forums.corvetteforum.com/c3-t...vette-v12.html)

If I drive lightfooted- I can easily see 20 MPG in my BMW...

The best way to save money -get rid of the vette!!!

But do what you want- This guy put a Buick V6 in his Aston Martin...

The Aussies have been hooning 3.6vvt motors for nearly a decade now - there are bolt on kits and all manner of updates for those motors.

The punch line is this - they are putting out more than 1000 hp from those little motors. When I started my Fiat, I talked to the head engineer at GM who designed the motor - they are a robust platform and easily capable of daily driving 500 hp (with turbos).... all without even changing the pistons. And as you well know, the 3.6l came also in similar-to-camaro sized Holdens (G8 and GTOs)

I'm going to find out.... but I devolve, the reason I chose the 3.6l motor was its amazing fuel economy. in 4000 lb cars, they get better than 30 mpg on the highway. I'm putting that same motor in a car that weighs half of that - and I don't care about heating cats, or any other tomfoolery emissions stuff, so I'm going to give it the full college try to get 60 mpg...

mock to your heart's content; and no, I'd never put it in my Corvette, however, that 3.6l motor has more stock hp and torque than a stock C4... and it weighs a bunch less than a SBC - so you can get a much better weight balance.... oh yeah, and while you folks spend $2,000 for 6 speed transmissions.... the Aisin transmission behind the 3.6l motor is capable of 500 hp and costs less than $500 from most wrecking yards (they also put that transmission in Toyota trucks, so there's a couple billion of them out there just rotting away waiting for the penny pinching hot rodder)

now if I could just get my wiring harness back .... I think when they said waiting is in the long, dark teatime of the soul; they were waiting for their wiring harness to be modified....

and - for those who might be considering these motors.... I have more header flanges

More stock HP, not more stock torque. Even the 84 Corvette came out on top on torque.

As for weight, you're right. I can't believe how light they are - even with 4 cams. 370#. An LS1 is about 460.

I would be lying if I said I wasn't curious how well one would run in a C3.

Best way to save gas money on a old vette is get rid of it. At this point with money I have spent on my LS conversion, gas would have to be 25 cents a gallon for the next 20 years before I see any payback.

I wouldn't swap out the sound of my V8 motor for a V6.

Meh....V6 sounding Vette. In the icon of American muscle? 53-55 was a learning curve.

To each his own. Nuff said.

You know..the idea of replacing the V-8 in a Corvette with a V-6... is JUST WRONG! The whole heart and soul of the Corvette is its V-8 engine. Rather then defile the Corvette, maybe you should search for a car with better mileage.

Not sure if I read that right, but the GTO never came with a 3.6l. At least in America they didn't. I wouldn't doubt Holden had them possibly in Australia.

get a buick 3.8l supercharged engine bolt a 460le trans to it. those engines are shorter in length an height it could easily have mounts welded into place to make it fit. who cares how if it doesn't sound like a 71 350hp 5.7l? So long as the guy with the 454 4 speed is spending $4.30p/gallon @ 5 mpg trying to pass beat you off the line and failing miserably. is say go for it if your gonna go, go all out get a beefy v6 that can haul *** when you need it to and be mild an fuel efficient when you want to cruise. your much more likely to make it your daily driver if you can afford to drive it. average American drives their d.d 20k miles per year. your saving will be made in 2 years time!

My 76 L48 roller cam,with 6spd Richmond gets 20mpg on the highway.The Richmond trans bolts up in place of that 4 spd.Your carb may be running to rich wasting fuel.Those new Street Demon carbs look like a modern Qjet and are getting great reviews...

But as far as putting a V6 in a C3, I say DO IT. I love how some guys get their panties all bunched up over engine swaps that aren't the status quo. You know what, fellas? The first Corvette ever made had an inline 6. All that matters in the end is how hard and fast that crank turns over. There are bone stock 4 bangers out there that put out more power than my L82.

I thought their V6 wasn't coming out until next year. The straight 6 is is a vastly superior configuration. Too bad it's hard to package.

Not the best evidence to support this argument. Corvette almost went extinct, and then they brought out the V8 in '55.

your best bet to get good mpg and not devalue the car would be put in a late model gm v8 with the overdrive trans with all the computer wiring .find a donor car that has what you want. when done it would have good hp ,good mpg and would be a good upgrade for resale.the first 6 cylinder cars did not do so well .
