I will be starting my duster project(no name yet) wich will be a daily driven 15 sec quartermiler,and i got a little confused on intake and carb choice,F.I is out and clifford is out,so i narrowed it to two choices : offy 4 bbl or offy dual webers? the part i got confused on is that people say dual webers is good for stock and not good for high r.p.m's,but the 4 bbl is good for medium or higher builds because you can get a higher flowing carb like eddy 500 or holley 650 etc...,and chris at proline claims that each carb could go to 400 cfm?? what do you guys think? should i go with a 4bbl offy or dual webers for my project? also should i keep my comp 252s or go with the 264s for my build? choices,choices!!
thanks

Dude if you help me achieve a 15 car i will name it slanted4life,if its better than i imagine i will name it parker4life !! please shed your wisdome,i am really in need of it
thanks

I feel that the Dual Webbers or a 4 BBL set-up can successfully support a 15 second Slant car. The difference is that the 4 BBL will be less expensive to dial-in and you will have more information and experienced people out there. (For some reason Webber knowledge is somewhat "lacking" in the US)

You will need more cam to get to your 15 second goal but watch-out, a 15 second Slant car is getting on the edge of "streetability". One thing you need to realize is that a 15 second Slant car needs to be light weight and needs low gearing, these needs take away from comfortable street driving.

If you car is basically stock now and you have the 254 cam, a intake/ carb and improver exhaust, jump-in and get that stuff installed. De-bug the set-up and you will know if the current engine will survive or if it need rebuilding. After that decision point, go after gearing and weight reduction work.

Dart4life how big is your budget for this project im sure me and Bagel can have you in the 15 second brackett also what your driving habits for the car, daily driver, street/strip, cruise in/strip all of this can make a deference on project costs and savings. Thanks Ron Possum Parker

Daily driver and 2,000

Keep an eye on the used parts sections of the boards and you should be able to achieve the 15's quite easily. Used headers and intakes pop up all the time, as do some decent heads and cams. Cut as much weight out of the car as you safely can.

I had my Duster pretty deep into the 15's and it was still very streetable even with 3.91 gears. I was using a Racer Brown 268/460 cam, which is not a whole lot different than a 264 Comp. When I had the same motor in my '66, it ran 14:80's. The key will be headwork. Good headwork will carry you farther than any camshaft.

My car has actually run faster with a 390 Holley than it did with a 500 Eddy.

If you want a daily driver, an Overdrive tranny is a great asset in reaching 15's and being able to drive it all the time. My sons 72 Swinger has a 4-speed OD. and 4.30 rear gears and it ran a severely traction limited 15.80 and he drove it approx. 8-10,000 miles in the past year. It has the same racer brown Cam that Dennis had and the car has not been lightened at all. The only exception would be a set of aftermarket front buckets.
Good Luck

dart4life trim as much weight of of the car that you can that is the best horsepower bang for the buck as you can do. Bagel is right the 390 cfm is the way to go. If you can budget this item the Keith Dorton 390 cfm doublepumper is the ticket. I ran one for three years if you can tune a Holly Carb this is the one. Adjustable one both ends i tried four different carbs before i hit on this one. Thanks Possum Parker

what are some safe ez ways to remove weight

If is a local daily driver get that spare tire and jack out of there. If only two people are going to ride in the car at a time buy to light weight poly seats from JEGs about 150 each with seat covers. Get rid of the power steering if it has one and put on manual steering, Lite weight Alluminum Wheels, Then with the overdrive trans and 4.30 gears, cam, headers, and the four barrel intake and carb you should run at least 15 .70 Thanks Possum Parker

The stock carpet and padding weigh a lot, also the heater box, especially if it's an AC unit.
I pull-out the window regulators for the back windows and just bolt down the glass in the closed position.
If you really want a 'fun' job, scrape-off all the car's undercoating. I got 30 lbs of undercoating off my last racecar. (the next time I will look for a non-undercoated chassis to start with)

The heaviest things in the interior of my car? The front bench, and then the seat belts...
