....yes, Jason Heffner is the owner/operator/builder.....
....one of my business partners and I took his 96 Viper GTS to Jason about 3 years ago.....Jasons shop was in Baltimore Md. then.....it was returned via enclosed trailer to his door with nearly 900 RWHP.....at the time it was built, it was the "Worlds First 9 Second Supercharged Viper"....Jason put it thru the quarter at 9.91, 148 mph....my Vipers are all relatively stock, I have driven the Heffner Viper a couple of times and it is the most astounding piece of machinery I have ever had the pleasure to drive....it sounds like a thunderstorm at idle, and runs faster than lightning.....I can't say enough good about Jason Heffner and his work.....I haven't visited him in Florida yet, but hope to soon....he has many happy customers and a great reputation, a real honest guy to do business with
