I edged out a charger SRT8 at the track that had intake/exhaust/tuning. He supposedly made 400 to the wheels, no proof though, I dunno what they normally dyno. I ran a 13.0 to his 13.1 on the pass that I went head to head, that was his best of the day. My next pass was the 12.8 in my sig.

And Indy Heads has a killer 426 based upon it as well. 426, Hemi, both combined equals lots of .

Charger is a 4100 lb car, so you should walk him. I hope the Challenger, based upon a shortened LX platform can get to 3800 lbs to be competitive with the GT500.

The 6.4 hasn't been officially confirmed by Mopar, but the insiders on the Mopar boards think it's a done deal. It will power the SRT Challenger and possibly the other SRT8s as well. Info on power is sketchy, but we've been told to expect "well over 500 hp". I don't know if that means 525 or 550 or 1000 or what, but there you have it.

As for Viper... magazine tests of the new 600 hp car vs the Z06 are still embargoed, but from what I hear, Chevy is going to have to up its game. The Viper is finally getting a half-decent interior too, but I bet it still won't be as good as the C6's.

No it isn't. The emissions regulations that kicked in in 1973 are what stopped things.

That's true, but... I think it's pretty cool that we live in an era where you can buy a big four-door five-passenger family sedan or station wagon that runs 12.9-13.0 right out of the box for reasonable money.

They are too heavy, and they're sorta ugly, too. But they're pretty cool cars.

WRONG!

See my sticky.

In 1969 things started to die. By 1972 you couldn't give muscle cars away.

"Emissions" & "fuel crissis",actually had zilch to do with muscle cars demise. Insurence surpluses killed it's sales, taking lead out of gasoline killed high compression engines, and the public by the early 70s looked at muscle cars the way alot of us view ricers today. A bit immature and obnoxious. This was when personal luxury coupes became the craze.

The REAL emissions standards didn't kick in till 1974/1975. By then, muscle cars had been dead already literally for years.

I guess I'll have to tell my dad he's wrong. He bought those 67 and 69 Z28s so cheap because the insurance costs were so high, not the fuel crisis.......

Right. It's a pretty odd existance indeed when people look at 500 horsepower (even on a 4000 pound vehicle) and a 0-60 acceleration time under 5 seconds and call it "Getting out of it's own way".

Might look up the weight of same-size Infiniti, Mercedes, Cadillac STS, or even a Holden Commodore V8. IRS, V8 engine, and full size equals at least 3900 pounds.

Cheap because he brought it in the 70s when those things were a dime a dozen?

Cheap because he actually bought them in 1967 and 1969 before insurence surcharges started killing off the cars, which started in 1970-71?

Okay, so insurance killed SALES, but there were still worthwhile muscle cars until 1973, regardless of how well they sold or what the general public thought of them. Emissions regs killed the CARS.

So although the public wasn't buying them and you couldn't give the things away, it's emissions that killed them?? That's like waiting 30 years and saying that high gas prices of 2007 killed the 4th gen Camaro.

Pontiac planned to bring out one incredible GTO in 1974 complete with the SD455 engine (same engine which survived this so-called deadly 1973 emissions rule... as did every other performance engine that was around in 1972.....in Firebird Trans Am).That car became the Grand Am. Ford pulled out of the muscle market almost before insurence started attacking muscle cars. Chrysler was setting up to move muscle to compact cars till they almost went broke and CAFE was passed.

A V6 Charger is about the same weight as a Taurus (3900 lb, plus or minus) and has about the same horsepower (250 hp, roughly). Nobody complains that the Taurus can't get out of its own way -- in fact, it's a lot nicer to drive than the 200 hp 500 it replaces. Same goes for the V6 Charger. Now take that car and DOUBLE the horsepower while adding 200 lb or so of heavier-duty parts for the driveline. You think the difference might be dramatic? Don't give me this nonsense about how it "can't get out of its own way". How many other 12 second full-size four-door family cars do you know of? Assuming you know of any, how many meet current emissions and safety regs and can be bought for less than $40k?

Yep, all those same engines were around in '73, but they were saddled with emissions hardware. The 1970-71 Buick 455 was rated 360 hp and 510 lb-ft of torque. The 1972-73 Buick 455 was rated at 225 hp and 360 lb-ft.
