Operator [op-uh-rey-ter] -noun a person who operates a machine, apparatus, or the like: a dyno operator. Opperator -noun (misspelled) a person who operates a smartphone (dumb phone) surfing YouTube, looking for something stupid to post. I generally don't respond to crank posts like this...because one thing that I've learned: "you can can win an argument on the internet with an idiot". HAVE A GREAT DAY!

Thanks for the shout out. It's time to get it out and run it.

Will someone PLEASE show the dyno sheet on a stock 426 Hemi. People still believe the old publishing specs of the 1960's (425 hp), which I happen to know is bull shit. I just want to have proof for the doubt-ers.

[black68gtx]

Let me know where to email you. I have the print out in JPEG and PDF.

i was wondering the same thing, but it could be because of the gears he has in it

@genXer3 dude i saw a dyno sheet for a stock 426 hemi and it said 650 hp and 664 torque. no bullshit.

One of the best Mopars ever, you had it if you had The 69 GTX. It could leave most other choking smoke while looking bad to the bone. Not a bad way to go around town is it? What's it get, 9 miles a gallon?

somone needs to teach the dyno opperator how to use it!

406ftlbs at 3500rpms. 406 X 3500 = 1,421,000 / 5252 = 270 hp at 3500 rpms. I am guessing your 306hp was actually at 4,500rpms. That would be a SAE net rating of about 370hp and a 60's gross rating of 480hp. Nice car!!!!

what a moron, he didn't even wind it up properly. I do hope this idiot dies of cancer.

The car looks so out of place on a dyno for some reason.

This screams daily driver like an angel from heaven. Show cars=people who are afraid to drive their cars.

@DrMMHMD the gear ratios decide how fast the drive shaft, and therefore engine, is spinning to make the wheels turn....a high gear ratio (5.13) means that the engine has to turn faster to achieve the same ground speed as a low gear ratio (2.73)
