My Valiant weighed 3530 lbs. The base engine was from my older racier car, indy RB blocked 528, Eagle crank, C&A steel rods, 31cc dished Ross pistons, 440-1 heads with 2.25" intake valves home ported, Straightline performance mech roller cam with about 260 degrees at .050" and 0.65" lift, indy single plane with a Chuck Nuytten pro street dominator, MSD 6 AL, 2" x 34" primary headers and 3" dual exhaust with x-pipe and four mufflers. CR was 11.3:1. Later we drove one season with the same engine in our C-body Plymouth VIP and run 10.6's with it with a PG, 4.10 gears and 32" tires. Because of only two gears it pretty much was equal to the 3.23 gers in the Valiant. The block, intake & heads are still in use in the current turbocharged engine that has pushed the C-body to 8.0's.

408 stroker,eddy aluminum heads 3.23 gear with a 26.6 inch street tire ran 12.99 at 107. It was only getting about 7/8 throttle due to adjustment issues. Plus I was lauching the car all wrong. 727 with stock 340 converter, in a 68 barracuda fastback.

I know its not a Mopar, but its impressive. Local guy around here.

1970 Monte Carlo, over 500" (555" i believe), car is all steel except the glass hood, with a full cage, smallish tire, no nitrous, 3.23 gears.

He comes to the track, bolts on a set of stickies that he has in the trunk, proceeds to go high 10's, bolts on the radials and goes home. I have never seen the car break, its super dependable. He used to slow it down and run the weekly street night when i raced also. That is a big car to go that fast on that little gear--its all torque.

My engine is the typical 500" street build. It has a small Dwyane Porter spec.'d roller cam. The et and mph in my sig was done at PRP last fall. The 60’ was 1.87 sec. and DA 1740'. I believe that there is another 0.10 in tuning alone, and maybe a couple more in really good air.

My goal was to be stock-like in every aspect of the car. It idles with 14” vacuum at 950 rpm in neutral and idles at 700 to 750 rpm in gear. The converter is very tight. It drives through the neighborhood at 1100 rpm in third gear like a stock C-body Chrysler. The tranny does not have PTK and will stay in third gear coming our of a rolling stop or turn. Other than the Wilwood front disc brakes, the suspension is not only stock, but original.

With that, I believe that with a 3800lb car, the right cam, headers, and converter and a typical 500" build, you could get into the 10s in a very streetable package with 3.23s without nitrous.

FWIW, many of the really fast drag radial cars are running in the 7s with 3.42 gears and 29-30 inch tires. I personally know of a Super Street Outlaw NMRA Mustang that has run low sevens at just under 200mph with 3.42 rear gears, 28x10.5 ( non W ) slick, 389ci single turbo ( I think it was a 94mm Turbonetics ) water to air intercooler, and inline valve Edelbrock Victor heads. The trans was a 1.80 Glide.

These cars load the converter hard through first gear. It would be like leaving in second gear for many cars.

A 10 second street car with 3.23s could be done with the right converter and most likely some sort of power adder.

It's pretty easy to run high 12's with a re-rung 440, small-ish cam and 3.23 gears as long as the car isn't too heavy.

A stock 350 horse rated 440 picks up about 50 HP with a simple cam, intake and carb swap as long as the bottom end and valve job are healty.

Pretty cheap, reliable and fun to drive combo.

I think the Mopar Action article mentioned that he was runnisg nitrous.

Dennis Jokela

Thanks for all the replies! The Mopar Action article is not clear to me if he is using the nitrous or not. But if you have it why wouldn't you use it?

What do you guys think the stall should be in a 500+ inch build like this?

Tim

We had a cheater kit too, but never used it at the track. It would have been quite interesting though, it produced quite a kick at around 70 mph on the street with 180 hp jets. I had a 9.5" converter, never checked the stall but I guess it was around 4500-5000. However, it pulled very well even below that and was a real pleasure to drive everywhere. PTC really nailed than one.

That is me and my pops car the article is on. And for all the doubters you can come to NC anytime and I will show you the gears, All steel panels 3700 lbs, or whatever doubts you have. It is a 230 block, stock caps, 440 source girdle, 440 source stroker kit, The old crappy 94 mopar stg 6 heads I cleaned up and worked over a little they flow 308 @ 700, but the cam isn't nearly that big. comp roller lifters, cheap press together pushrods, Harland sharp rockers, Indy intake, The carb is from a roundy round shop near our shop they said it flowed about 920cfm.No cage just 2x3 sube-frame connectors. 2 1/4 hooker super stock headers, homemade 3" x-pipe and cheap dynomax mufflers and not bullets. The converter is a 9.5" dynamic converter, flashes about 3800 with .065 nitrous jet and has been the 10.26 @ 134 with the 100hp of nitrous and has been 10.70 @ 125 on raw HP. It is sitting in our garage right now for any doubters.

After talking with pops about this post my Duster I had a 3.25 gear a couple years ago and went 5.85 @ 118 with a 1.30 60' footbraking. 470" lowdeck,stock crank, source rods, ross pistons, max wedge stg. 6's, indy intake, 1050 4150 carb, 9" converter flashed 3600,727 2.77 low gear, 300 hp with a plate kit. stock front suspension, caltracs-monos, 8" wheels 26x11.5 et streets, 3275lbs. here is some vid from back then.

Heads-up, thanks for posting some more details on your car! I like it! Would you consider using an RB with a 440source 528 or 543 stroker kit for a build like this?

Shaker223, boost is your friend! Can you tell us what kind of time and money it took to get your slant to go like that?

These lower buck builds are cool, do we have any more?

Thanks

Tim

People just can't get it.The fastest Mopars come from NC.It's in the moon shine or something.I have seen Mike run that old turd all over the place.It does run good,but I think he's scared of Buster Brown.Lenny

My street car 500" 590tq 511hp ran 12.10 with 3.70 gears. Couldn't stand 8mpg! Switched to 3.08 and still ran 12.30. Big torque down low doesn't care much about gear. Speed up from 110 to 112! 64 sig car loves 4.89, might try 5.13. Different animal.

BSB67,That is a awesome combo

AND Buster Brown is BAD A$$
