first off, no i dont have anything in the works, just wanted to start a discussion. if you were to build a mopar in the 3100-3200 lb range, drag radial tires (315's) on caltraks/maxtracks and were shooting for high 7's, what would be the minimum head (B1, MC, ect...)? also how big(cid) minimum? must be on nitrous, how many stage? i'm not talking one miricale 7.99, but a high 7 second car. what say you...

I've thought about this several times. Drag Radial is one of my favorite classes out there. I honestly do not think that a leaf spring car can be consistent enough to be competitive in Drag radial.
With that being said, if I were to try to build a 7 second DR Mopar and keep it Mopar powered, I'd build a big motor like a 572-588 or bigger and hang a pair of turbos off of it. ( not sure what the rulse are out there for BB/turbo combos, but I think Paul Major runs a 615 ci mill ) I would mount the turbos up under the front fenders behind the tires. Big stuff 3 management system, glide or turbo 400 and a set of 3.54 rear gears.
As far as body style is concerned, there really isn't any "aero" mopars, so a Duster like yours or a Dart like mine would be the body style of choice.
One big investment on such a car would be a VERY good pair of shocks both front and rear. I'm not sure what would work for the rear suspension. My theory would involve a split leaf like a Caltrack split mono but with a VERY stout stiff front section.
I'm Gumby dammit!

If I HAD to run Nitrous, I'd build a 632ci Chevy with a BMF or Big Cheif head. I think most drag radial rules only allow one stage.

I'd probably use a '67-up Dart (a little more rear overhang) with a 604+ inch Predator headed mill. CHIP
CHIP '70 hemicuda, 575" Hemi, 727, Dana 60 '69 road runner, 440-6, 18 spline 4 speed, Dana 60 '71 Demon, 340, low gear 904, 8.75 '73 Chrysler New Yorker, 440, 727, 8.75 '90 Chevy 454SS Silverado, 476" BBC, TH400, 14 bolt '06 GMC 2500HD LBZ Duramax

Current record in outlaw drag radial is 6.89 at 214 mph!!!!! Average times are 7.10ish, That's gonna be extremely tough to beat on leaf springs,not to mention very expensive. I got the heads you need to make the power,it's getting it to the ground that's the problem. Predator headed 604/636 with 1 stage. If you decide it's in the budget,give me a call

If using a car with poor aerodynamics, target 1400 HP on one stage because of the inefficiencies of above. Then try snakeing header tubes around an already tight engine compartment. Mike and Jerry's car comes to mind as a great example so, it can be done $$$. But I'd use a turbo or one of themtheir Prochargers.

One day if I ever win the lottery Iwill have one! lol But it would be very hard to do with nitrous. I mean it would have to be in the 620- 650ci range with 3 guns on it. Most of the fastest drag radial nitrous cars are single carb cast intake. Jason black that won last ORTC has a cast alum tunnel ram with 2 1050's and 3 guns. The 762's with split doms and 4 guns arent really faster than cast intake smaller engines in drag radial. My buddy Jason Richards has a 68 camaro leafs/caltracs, 632 with big cheifs, 2 guns, cast intake 1 carb has been 4.88 @ 150 @ 3100lbs. I just don't think that would be the way to go though. If there was no budget I would do a 604ci Predator headed engine with a 131 or a 139 f-3 or the new twin f-2 set-up. glide, 9". In a 68 dart.
One day I will have something cool here.

How about a new challenger with a triangulated 4 link? If it was going to be a leaf spring car, consider using chevy spec springs, with a 25 inch front segment instead of the 20 A body springs to get the IC out there a little closer to where it should be. Sure there would be some fab work, just a thought.

First off, he said "nitrous car". The fastest nitrous radial car in the country, be it Ford, Chevy, whatever, runs in the 7.50s. You will NEVER compete with boosted cars, so you can't even entertain that thought. There are a few leaf spring cars running 7s in the 1/4 and 4.80s in the 1/8, so it can be done. As far as power, a Predator headed 632 with 3 guns would be relatively competitve. These cars are more about power management than pure power. As stated above, the guy that won the nitrous side at the ORTC race, had a conventional headed 632 with 3 guns on a tunnel ram and went 4.76 in the final. The runner up has a 632 big chief motor, with a single 4 and two kits and he went 4.82. The big chief motor makes more power, but the 60ft decided this race.

1st you have to decide what you want to race in class wise. Many 275 races out there and 315 races. A leaf spring car can be made to work but in all honesty a newer camaro or mustang is a way better platform than a mopar. If you put a ladder bar under them you have a weight penalty if they allow them. If you run leaf springs they will work but I think it takes much more time to get them right than the newer cars. But really you need to pick the class and organization you want to run because at least in 275 they would not allow predator heads.
