'13 Ford Shelby GT500 most powerful production V8

[J-440]

Ok well now we are talking production numbers, maybe I should retract my statement. I'm one of those rare Mopar guys that thinks the HEMI is way overrated. Good motor but ridiculously overpriced. I give respect where its due and Ford has definitly upped its game.

Yeah but advertised HP vs crank HP were way off. Manufacturers lied to the insurance companies not to mention the opposition on what was really under the hood. 426 HEMI with 425HP...ha!! An LS6 with 450HP...yeah right. Old timers will tell you this. Man the 60's were great and I was born too late!!

Yep, there are plenty of us old-timers here that lived it.

And it was great.

Yea that's why the NHRA has their own hp handicapping scale for stock class.

The Hemi is like the Boss 429 Ford. Lots of potential if done right.

Did you finish that Charger of yours? I don't think I ever saw a finished pic. Sure is a cool looking project.

I want a 1970 Superbee with a six pac 440 with the ramcharger hood for my Mopar ride (I always like the ugly ducklings I guess). That round tai-light charger would be high on my list of must haves.

Remember that they can pick the hp number from anywhere on the dyno sheet -- they never said ''425 hp @ 4600 rpm" -- nor did they mention TORQUE (the only true measurement).

Also PRIOR to 1973 they were rated at SAE GROSS... in other words - no accessories etc -- after that they were rated SAE NET with accessories as installed in the car.

Most of the whole under rated deal is legend. HP has come a looooong way in 40 years. The 69 ZL1 didn't make anywhere close to 600hp. I'd say, maybe 500.
