Congrats to Brian and Gene Wilsey on resetting the FAST small block record.(which they had prior) Brian was able to pilot his 1971 Duster 340 to a new low 10.39 et at a blazing 130 mph on a G70-14 tire!!! In my opinion, one if not THE most impressive cars in the class. This car and its engine were built in their garage at home. It is made out of the correct parts with no (FAST approved) castings .Many lightweight and free flowing pieces were fabricated as well. This car embodies the original intent of the class.

A round of applause for Brian and Gene...Good job fellas!

nice job

That's outstanding when I compare it to my old 368" racecar Duster.
It was a bit quicker with a lot more tire @ about 640 HP or so.
Obviously they apply their power more downtrack; 3rd gear must really be a hard pull !

Serious bonus points for looking so stock and unassuming !

First round the Duster went a little quicker.

That’s impressive!

I'd love to see the tricks in this car. Very impressive.
Doug

That is incredible...

Any pictures of the car?

Found this from 7 months ago....

I remember 20 years ago suggesting to Tom Cannon and others in FAST 20 yrs ago that I thought a 71-72 340 TQ duster or demon would be a faster combo than a 70 Challenger six pack and might rival a hemi E or B body in terms of 60' and 1/8th mile times.

I don't know if anyone remembers but I had actually bought a 72 duster Twister /6 car and a 340 and 904 with the hopes of building a 433" FAST car. but work sent me overseas for months so I sold the project.

But I'm so glad someone else came through and Proved my prediction correct!! LOL

congratulations!!, I don't know everything they are doing but I'll bet I have a pretty good guess!

But I had figured out the cam 'secrets' a long time ago anyway, before some of them did!

But the short front and long rear overhang and the light weight of the Duster make it the most natural Mopar Drag car there is, and the roofline is more aerodynamic than a Dart or 67-69 cuda body.

10.30's on 14" tires and factory castings....That's truly astounding!!

I was thinking you could get a 71-72 duster to about a 2700-ish legit pounds and still pass FAST tech.

BTW who did he run in the other lane that went 118 in the 1/8th and "only" 123.xx in the 1/4? Did he run out of nitrous 1/2 way down the track? (I'm just kidding!)

Judging by ythe 1/8th mile that was a 9 second car so probably DD, 118 in the 1/8th would be way too slow to be a Pennington car!

Nice job.

Well, my mind has completely exploded after seeing the above time slips

I wish I understood the rules more but from what I understand it’s not your everyday common compound street tire. Big cubic inches. Big manifolds modified of course. Are Grids aloud to pull timing??? Any head modification that aren’t legal??? Compression limits??? What rear suspension are they allowed? I’m guessing large. And are aloud. Any ring pac rules.

The tires are reproduction bias ply tires , nothing special about them other than they hook better than the originals, some people played with traction aiding substances but it didn't really help, track prep is very good when these cars run I assume ... I haven't run since '06

Yes it's over 400 CI ,

Stock 340 A body exh castings that can be ported and polished as they see fit, 2.5 inch max pipe size to the rear bumper, stock looking mufflers in stock location , straight thru ok , X pipe ok

No idea what the grids are but they are allowed to run a digital type ignition with a stock looking dist housing.

Compression there is no limit

Rear suspension is factory stock style leafs and a race shock , no caltrac type , no slapper bars

No ring pack rules, there is a cubic inch limit on big blocks , not sure what it is on a smallblock ?

Roller cams allowed , aftermarket rockers allowed but they need to fit under a stock type valvecover 2 gaskets , no spacers ... the valvecover rule does not apply to the BBC, they can run an aftermerket that is MUCH taller , no one makes one for other makes ?

The cars I've seen follow the "stock appearing" part very closely. However, I gotta call bogus on the "stock sound" requirement cuz some of those cars OBVIOUSLY have way more cam than any OEM I've ever heard. They might as well just drop that, cuz according to my ears, it's not being enforced anyway.

Thanks. I know something cam up the up the other day that I think a 1/2 inch wider wheel was allowed which would help with the footprint. I’m assuming a 904 with lite weight parts are allowed also.

The F.A.S.T class is awesome. One of my favorite classes of racing. All of these cars are impressive.

I read the rules and there are a lot of “grey” areas that you would have to learn and push to the limits. Are they allowed and do they shave their tires. Living close to Lernerville dirt track I know those guys have lots of tire tricks.

Forums have the most knowledgeable members. But Face Book Groups have taken over. The FB Groups have NON knowledgeable members. I was reading the comments of this Duster on the FBG. The majority simply does not understand- "Factory Appearing Stock Tire." Many members dumbfounded and naysaying that a stock Duster 340 is so fast. It's not stock. Only thing stock is the appearance. That's the point. Gotta select a car and available drivetrain that will lend itself to heavy modifications internally to make BIG power. That's why the Hemi did so well in this class. Factory high flow heads- great induction and great flowing exh manifolds.

The consensus among those that have experimented with them is that they work best when shaved down to the wear bars and have minimal tread showing. No chemicals added.
