Those Cuda's are no joke. My friend has a few of them.

Is that a real 71 Hemi vert?!
Pick your poison.
Yep. It's a pretty spectacular collection. Behind it are two GTO Judge Ram Air IV 4-Speed convertibles. And just past those is a 69 Trans Am 4-Speed convertible. Did I mention the pair of Yenko Camaros and the 69 Camaro Indy Pace car, one of two built for the race? Oh and he also owns what I consider the crown jewel of the collection- the "Dick Smith" Cobra. It's good to be the king!

What are the mods on the Hemi?Wow, those cars are making an honest 500hp
It says pure stock muscle car drags. I believe they are pretty strick on rules. Its not like the F.A.S.T. racing. I think they are only allowed like digital ignition 2.5in exhaust. Maybe a cam? They are just really really tuned well. The F.A.S.T. class is a bit different it's factory appearing stock tire. Those are completely worked motors bored and stroked, tons of port work very worked over stock carbs. But they have to LOOK stock on outside. Hemi's tuned and running right are no joke those heads flow really well and older mopars weren't that heavy they were unibody cars.What are the mods on the Hemi?
it has a custom camshaft with stock specs as allowed by the rules. the cam must spec the same as stock when measured and still pull vacuum like stock. basically, it has faster opening ramps and thats about it. here is an interview from bab k about the hemi cuda:What are the mods on the Hemi?
Bob Karakashian is a well-known Mopar racer and former IHRA record holder. Ask any Mopar guy, and they'll say that he deserves some kind of lifetime achievement award as a front-of-the-pack fixture. The Cuda has run a best of 11.59 at 121.25 at Milan, and at this meet, he qualified 9th using old reproduction Polyglas GTs.
Bob says that there's no real trick to making power with the Hemi.
"The Hemi makes the power by blueprinting," he maintains. And his 'Cuda engine is pretty conservative. The block is .060-inch over, the crankshaft is a standard factory-forged unit, and still uses a factory balancer. The connecting rods are stock-style forged Manley I-beams, and CP pistons with the stock ring package finish it off. There's nothing trick, just very careful attention to machining to ensure cylinder sealing and minimal friction.
One thing that Bob insists on is his proprietary "Mr. Six Pack" camshaft. "My camshafts look small on paper, but have a much faster rate of lift," explains Bob. "Mr. Six Pack camshafts are very close to stock lift, and are single pattern just like the factory. They use the fast ramp that Mopar used back then. They're not Chevy lobes like most cams use today."
The balance of the valvetrain is all stock—rockers, shafts, and a single valve spring that the factory had on the '70 Hemi. Like we said, no porting or even port matching is allowed.
Bob hasn't dyno'd this engine, but he did dyno one virtually identical, which made 565 hp at 6,700 rpm.
Bob's 'Cuda is a column-shifted automatic, and he rebuilt his own TorqueFlite which, like the engine, is essentially stock—no rollers, no aluminum, all factory parts.
"The torque converter is an 11-inch Turbo Action that's been in the car for about 20 years. Stall speed is about 1,800 rpm—I'd like it to be about 2,000 or even 2,100."
The axle is an 834 with digger 4.30:1 gears.
The 'Cuda makes good if not spectacular power, but driving it is a big part of its success. The Hemi can easily overpower the tires, even on a sprayed starting line, so Bob brings it out just above idle, then gets into it once the wheels are rolling, and 60-foots in the low 1.80s.
"With an E-Body, it's a little bigger challenge to get the car to launch because there's no [rear] overhang," says Bob, who is accomplished as both an E- and B-Body pilot. "When the second carburetor kicks in, it's really violent. The back of the car is so light, [and] that's part of the problem. Unlike other racing classes, the faster Pure Stock racers usually have to add weight to increase traction and go faster. With Bob aboard, his 'Cuda weighs 3,765 pounds.
If you can exercise throttle restraint in the early going and not give the race away in wheel spin, the Hemi will rally to win a lot of races.
"The 440 Six Pack has the torque off the line, but the Hemi has a top end charge that out powers it. The Six-Pack, up to 800 or 1,000 feet will run with a Hemi all day long, but [after that], the Hemi takes over like gangbuster."
Last year Bob ran 11.62 at 121 at the Pure Stocks. He was off over three tenths this year and thinks he knows why.
"I had different fuel with a pinch more octane and I think it actually slowed the car down."
That is one impressive Hemi collection!Those Cuda's are no joke. My friend has a few of them.

That Trans Am vert is one of EIGHT produced. That's EIGHT... as in the number after 7. 4 of them were Auto's and 4 were 4-speeds. Talk about rare. Your friend has a sick collection. WOW!
