I dunno...same as working on an old house, whatever. Put on a mask and go to town. Take a hose to the whole thing if you're taking it apart anyways. It's not a new or uncommon process and it's not like there's guys dying left and right.

1972 Plymouth Duster - Slant Sick
"They all thought I was nuts," Steve Nitti tells us as we marvel at his sick creation. "I bought it new on January 3, 1972, at 2:32 p.m. for $2,200." Yes, he knows the time of day he bought the car. That fact is also verified by the builder, who could recite that phrase off the top of his head too, even though he'd finished working on the car nearly a year before.

In 2006, Steve dropped off the car at Sharadon Performance in Hugo, Minnesota, for a full restoration. On top of that, he says he wanted the Duster to run 10s but still be streetable." Though he had originally purchased the Slant Six car because the insurance was cheaper, over the years, Steve longed to transform his Duster into a street/strip machine. Denny Baierl, whose father owns Sharadon, replied, "You're gonna need a supercharger, fuel injection, and a lot of money." Steve didn't blink. He wrote a check, and Denny got to work.

It took about two years to complete the car, which really isn't out of line for a restoration, but it is quite impressive considering how much custom work Denny had to do to make a Slant Six make a bunch of power. "Nothing was easy. All the engine-related work was a battle," Denny says. The particulars will be in the following tech notes section, but the Cliff's Notes version is this: more displacement, custom machining, really expensive custom parts, and an even more expensive handmade intake manifold.

Steve was thrilled when he finally got to drive the car again. "He looked like a kid in a candy store," Denny says. "He tools around town and takes it to every car show he can make it to." It draws lots of attention, as you'd expect. And along with that attention comes the inevitable question: Why? Steve just likes this car. He has other Mopars, including a really nice '67 Barracuda, but this Duster is the car he's owned the longest. It just resonates with him. Wanting to make the car you love better is a natural desire we all can relate to. Yes, it would have cost him less to build a 340 that knocked down similar e.t.'s , but as Denny says, "You'd walk right by this car if it had a V8 in it. With the Slant Six, everyone stops to look.

With a best eighth-mile time of 7.18 at 98.23 mph and a 1.60-second 60-foot time, Steve hasn't quite hit his goal of 10.99 in the quarter, but he's close. With some more tuning and a better launch, he will get there soon.

Tech Notes

What: '71 Plymouth Duster
Owner: Steve Nitti
Where: Scandia, Minnesota. If you're in the area, visit the Erickson Log House Museum.

Short-block: The iron-block Slant Six was bored 0.020 over. Denny managed to find a forged factory crankshaft and had it offset-ground to add extra stroke, ending up with a spec of 4.30 inches. Carillo made a set of connecting rods for this application, and the pistons are custom forgings from Ross, made to Denny's specifications, that yield a conservative 8.0:1 compression ratio. To fit this package inside the block, the bottoms of the cylinders had to be clearanced, which is not unusual for a stroker build. What made this application interesting, however, was that the beams of the connecting rods interfered with the cylinder walls because the stroke was so much longer that the Chrysler engineers ever imagined when this engine was designed. So rather than the minor machining typically needed to clear a connecting rod bolt, lots of careful grinding had to be done inside the crankcase to make this rotating assembly to fit.

Long-block: Denny ordered a custom-ground Crower cam that's able to deliver 0.530 lift, a whopping 36 percent more than stock. It controls a set of oversized valves (1.80-/1.50-inch) inside a fully ported cylinder head. "We ruined one head trying to see how much bigger we could make the ports," Denny says. T&D makes the roller rocker arms, and Denny fitted a set of beehive springs under them. By their nature, inline-six engines have long cylinder heads that need lots of clamping force to remain sealed, especially if any power-adders are introduced. Denny told us that just 10 psi of boost pushed out the stock head gasket, and 20 psi lifted the head. Now they use a copper shim gasket with ARP head studs, and everything has been OK so far.

Supercharger: That's a Procharger D1 centrifugal supercharger breathing directly into the intake manifold. The Supercharger Store in Huachuca City, Arizona, actually makes the mounting brackets for this application. The blower delivers a maximum of 26 psi of boost, though Denny says the engine normally runs at about 20 psi. There's no intercooler because Steve was worried about clearance issues behind his cherished Shark's Tooth grille, so Denny decided to run the car on E85 fuel with a shot from a water/methanol injection kit to cool the intake charge.

Intake and fuel delivery: Stock intake manifolds for these engines are long, skinny affairs that do not have the cross-sectional area needed to deliver the amount of air this engine needs to go 10s. So knowing he'd need to have a custom intake manifold made, Denny decided to build an electronic fuel injection system to go with it. The sheetmetal intake is handmade for this application, and the FAST XFI monitors the engine's vitals and controls the 80-lb-hr fuel injectors accordingly. An Aeromotive A1000 pump in a sumped gas tank keeps up with the excessive fuel demands.

Exhaust: The header is a custom 3-2-1 setup with 2-inch primaries feeding a 3-inch exhaust.

Drivetrain: The trans is a Chrysler 904 with a 5,000-rpm Midwest converter. It turns a Victory Driveline driveshaft connected to an 83⁄4 rear axle with a Mopar Performance aluminum centersection, Moser axles, and 3.91:1 gears on a spool.

Suspension: Under the front of the car is a Magnum Force front tube chassis with QA1 double-adjustable front and rear shocks. Mopar Super Stock leaf springs and QA1 shocks are out back.

Interior: Legendary reupholstered the seats and interior to a like-new stock appearance. The chromoly six-point rollbar was bent and fitted by SharaDon Performance.

Paint/Body: Steve's Duster needed a complete restoration when he dropped it off at SharaDon Performance. It is basically a one-stop Mopar build shop that can do general repairs, performance modifications, and full restorations. Sharadon replaced all the rusty sheetmetal and massaged the remaining panels to an arrow-straight finish before respraying the car in its original Poly Gold Leaf Metallic. Along the way, Denny managed to persuade Steve to lighten the car as much as possible. You won't find windshield wipers, a heater, or air conditioning. They also replaced the hood and front bumper with fiberglass and were rewarded with a 2,995-pound curb weight. The one thing Steve wouldn't compromise was the radio. Guess his tunes are as important as his timeslips.

On the road: "It sounds crazy. Everyone looks over to see what's making the noise. They look over and keep looking at you like they can't process the sounds and the car that's making them," Denny says. "It drives like you'd expect a drag car to, but unlike a V8, it doesn't make a ton of power below 5,000 rpm. If you keep it above 5,000, it's really fun to drive."

oooooooo Duster!

I'll have to get some photos of the collection my girlfriend's dad has in his warehouses. Some of your minds would spray brain-matter all over the walls.

I had a black/black '72 Duster 340. It was my first real car and had a Crowley cam, Jardine headers, Mallory ignition and Ansen mags. Thought I was a bad ass in that car (but really wasn't, LOL).

Ken I keep forgetting about the list of cool cars you said that you and your family has had. '72 Duster was certified bad ass! Was it anything like this?



I like this clean Resto-mod Duster

Resto-mods make me harder than a high school chemistry nerd on prom night.


I'll grab photos of the collection when we fly back to MN....whenever that ends up being (with my luck it will be during the dead of winter).

Boss,

It was exactly like the black one. I paid $1,200 for it (used). Drove it all through grad school and gave it to my older sister when her Javelin SST crapped out on her. She drove it for a few years, blew the motor and my dad installed a spare 318 he had laying around (my dad was a Mopar guy through and through). I always like the factory wheels, even more than my Ansen mags, but they weren't wide enough for me. The blue car up above appears to have larger, wider aftermarket versions of the factory wheels, which is exactly what I would do if I was able to do it all over again.

Ken.

Not surprised to see this, but it's nice to see him excited about the design and craftsmanship, as well as lowriding getting the recognition it should. I'd say 99% of these guys are just working stiffs doing a 9-5. That orange 63 is insanely done. It's not my style, but WOW the quality of craftsmanship, design, and detail is absolute. The lines on that '66 @ 6:11 with all that sexy gorgeous black is amazing! That black, wow. Color calibrated monitors FTW! I figure I'd post this as I know even though y'all like your 1,000 HP Supras and 1500 HP TTGs, y'all still would like to have a '64 Impala convertible on D's with switches. :hide: Everyone does, I think. Or, at least have fun for a Saturday night cruise in one. That 409 threw me for a loop, damn, wtf?! Sounds good too. Engine bay, shit. man. The fuel injection is definitely cool too. The style isn't entirely me (the '66, yeah I likey), and I know some people rag on lowriders, but the way I see it is that it's better to see these ol' gals on the street like this than rotting in the field where they found them.






Here's some car pics. A bit of a x-post, but it's an appropriate x-post. :dunno: I like seeing this in the driveway though. Anyways, this is part of the way of how I take car photos, and I'm proud to say I wouldn't have it any other way. :D



These two are quite similar, but the black and "charcoal gray" really do look well together as well as the red and yellow up above.



Really keen on this one. I think it's the tonality. I especially like what's going on in the "hip" area. :) Plus, how the lines and curves are leading towards the 911/vanishing point. I really do adore night shots of cars. They seem so much sexier, sleeker, dramatic, and far more poignant with how the attention draws towards them.

Was thinking about this thread the other day, and I told myself, "I guess big bodies and hot rods don't exist in the winter". Ha

BUMP!

Im gaining an interest in late 70's and 80s American cars, like the Monte Carlo and Cutlass Surpreme...and i discovered this Hurst gearbox!

I'm starting to warm up to them as well. I like the G-Bodies, but I think I like the front end of the Cutty's a little more. What do ya have in mind? Hurst gearbox didn't show up, link?
