    Looking for fuel pump/pressure regulator advice

    If you have too much fuel pressure the fuel should be overpowering the floats in the carb if that is the source of the rich condition. You would see fuel dribbling in the throat of your carb while idling. If you have a rubber fuel, (pressure of suction side of pump) you could pinch the line to...

    Odd question about tires

    If your car is accelerating hard the tires will have wrinkles all the way down. Have a friend check your black marks on the starting line. Low air pressure will cause two dark lines at the edge of your tire print. To much air will cause a dark spot in the middle. Even darkness all the way across...

    I lost a great lady

    Mike, you are very lucky to have had someone as special as your aunt in your life. It sounds as if there will be many stories to tell with your family. God bless you and your family. I bet she cooked as well as she hunted! From a fellow arky, Ray

    After Market 4.5 inch A-body 8.75 Rear Drums?

    If you want to use the 1.75 backing plates and redrilled axles, ford ranger drums are the closest fit I have found. I put them on my sons 72 Swinger. You may need to grind the lip of the backing plate down 1/8 inch or so, or it may drag on the drum. Ours have been on for year and a half with no...

    super comp headers installed

    Hey guys, I asked back in the fall for suggestions on replacing the headers on my drag car. The most popular choice was super comps 1.75 primary so I bought some and installed in place of my cheap 1 5/8 headers. My combo is a 408 11 to 1, j heads with good porting, 560 lift solid cam, victor...

    Balancing cast crank 340

    Chuck, is that 719 grams without the wrist pins? If so than the new pistons I have would be very close. I wonder how the machine shops balance a crankshaft without having the torque converter bolted on when working with an external balance. My machinist told me he has only done internal shafts...

    Balancing cast crank 340

    318 crank would fit then? I know they are internal balance and most are cast. Cast would be ok for this street build. If i use an external balanced shaft, how do I keep the stator in the torque converter from moving around while it is bolted to the crank during the balancing process?

    Balancing cast crank 340

    I hope you guys and gals can help me. I am rebuilding a 72 cast crank 340 in a numbers matching car. It is a late 72 model so it has a cast crank as the 73s do. I want to earlier 340 pistons to regain the compression that is lost in the 72 and 73 models. Does anyone know the correct weight...

    70 dart swinger bumper on a 75 swinger?

    We did the same swap as you on my sons 75 valiant to make it look as a 72. The entire rear section with the bumper support braces have to been used from the 70-72 model. Here are a few pics. This one is of the finished car. http://i222.photobucket.com/albums/dd145/ray79rt/72swinger.jpg These...

    904 "braking" in 2nd gear

    Odd problems like yours is usually caused by the trans trying to shift into two gears at once. I would suspect that the rear band may be trying to apply when you are in second. (or maybe direct clutch pack appling instead of rear band, either one would cause your problem) Second gear should...

    cam thoughts

    I love my 268/454 cam in my 318. It sounds nice but still works well with stock converter. Mine is alittle soft below 2500 since I put 360 heads on it, (that dropped compression alittle) but it will still smokem with 2.71 gears.

    strange things are afoot at the circle K!

    A guy in town has his purple 68 Nova sitting by the highway with a for sale sign on it. This caused a big rumor at the high school that my oldest son was selling his "muscle car". He drives a plum crazy 74 PLYMOUTH DUSTER. I was asked by several of his friends at ball games "Why is Thomas...

    225 to 318 question

    By the way, do not let anybody cut your shaft in the middle and weld it up there. I took the shaft out of a 72 duster I am restoring and that is what I found. I can not believe the car was driven that way, it had to vibrate like crazy.

    225 to 318 question

    The shaft will have to be shortend for both the 518 and 8.75 so try to install both trans and rear axle at the same time to keep from cutting the driveshaft twice. The 518 (and 500) takes the same yoke as a 727, so that is easy to find in your small u joint size. Alot of the factory drive...

    I love my old mopars with a passion. I also am looking forward to driving a new challenger if I get the chance. It may take awhile but I am patient.

    wheres the lowend tq...

    With a good convertor your engine should never see 3500 rpm. It should be launching above that. As far as never seeing 500 hp with j heads, bullshot, I run 6.65 with j heads that I ported with no flow bench with .565 lift cam. J heads will make torque and horsepower but it is easier with a 360...
