There is such a pkg. by John. Over the years he has done many mods to Vipers from 500, 600, 650, 700 HP packages and much more. He adds various bolt ons plus internal upgrades depending on what the customers wanted to get the desired HP.

Its to bad Hennessey hit his head on something.:dunno:
He must have hit it just right as for years he has been the leading car performance tuner breaking all sorts of records and highly respected in the performance auto industry. He did awesome work on my old GTS years ago but some people just seem to remember the bad times/news times years ago for some unfortunate few. Times have changed and he is very successful now.

He did treat owners from Texas a little different then the rest of the USA and overseas. I wouldn't trust his crap one bit as described. I can't argue with his stellar marketing ability to stay afloat with bad reviews everywhere.

the problem is once the word is out and its not good, it would haunt you and your reputation. And it proves on this forum and other forums as a close nit community Hennessey is not to be trusted. It just turns a lot of people off.

Unfortunately, I have to agree that I would never buy a "H" car. That's crazy money for a Gen 1. This was during the time that what you bought and what you got were questionable from him. As a matter of principle, I would run and not walk away from his cars.

Seen quite a few cases of tuners/vendors screwing customers over the years. And if it wasn't for forums like these, we would never know.. especially us overseas customers.

Oh come on!! lol.

This guy purely took hard earned money, money that people use for their families and lively hoods and treated it like it was his own. I give you money and you give me a product. THE PRODUCT I ASKED AND BOUGHT, not what he perceived as bought. When I pay for a certain build, a build you said you would do with certain brands you said you would put in it, I darn well expect that to happen. ESPECIALLY WHEN ITS MY MONEY PAYING FOR IT !!

Who did he think he was to play around with peoples money., and you sit here supporting him. You have to be kidding. Is that what you would expect from your hard earned money? Would you have been ok with that? Do you support those business and people who have done that to you in the past.

Anyways,

Hennessey is a snake and slimeball. I would not trust him making me a go cart. If it a spade, call it a spade.

He's a talented tuner for sure. Good at marketing for sure. Unethical, absolutely. Any claim that "now he's better" will always be suspect. Ethical people would NEVER do the things he did to some.

You are brain washed. I would not trust him with one penny. If you like him thats fine, but do not try and tell me how good he is now. He has screwed hundreds of people.

+1 Even more because now second hand owners don't even know what's really under the hood. A Venom 500 might only be smooth tubes and a sticker. A Venom 600 might only have headers. Nearly every H-build is a mystery.

So the video states the Venom 600 is a stroker bored to 514 cubic inches, anybody ever confirmed this? Sounds fishy.
I can confirm it as I saw the car shortly after the video was taken at HMS shop years ago, and also saw all the engine blu printed specs. Got to see the boring machine too in action. His shop now is unbelievable with a cool drag strip out back.

My business was located directly across from Hennessey when this old youtube was filmed. Was always fun to watch him test out the cars!
