    Dart Sport on Marketplace. Not mine

    A few pic's she took while loading it up on trailer. My son wants to put the engine together and stuff the engine and trans back in, and clean it up enough to start driving it. Probably put headers and dual exhaust, Got a full set of Weld rodlite wheels to put on it, a shift kit in the trans...

    Dart Sport on Marketplace. Not mine

    My son bought this car on Monday and I drove a little over 2 hours to pick the car up. The Dart has the usual dings and chips you would find in a 51 year old car. Rust for a car that has been in the north east its entire life is minimal, drivers side floor has a few small holes and a little...

    2017 ram 2500 broken manifold bolts

    And the win goes to Dale Davies, Thank you! You wouldn't believe how many people will argue that the gr-8 shear strength is greater because the bolt is stronger.

    2017 ram 2500 broken manifold bolts

    Now my question is which bolts have the higher shear strength, a gr-2, gr-5 or gr-8? On the subject of studs and nuts, the GM LS engines and the Ford Mod engines both use studs and they are both having the same cast iron exhaust manifold attachment breakage problems as the new Hemi that uses...

    2017 ram 2500 broken manifold bolts

    So now a hypothetical scenario, The manufacturer decides to put the manifolds on with 3/8 grade 8 bolts now, to cure the problem of 5/16 low grade bolt snapping. The 3/8 bolt cost more but is much stronger, so now that bolt pulls the threads out of the aluminum head instead of breaking. How much...

    2017 ram 2500 broken manifold bolts

    As much as a lot of us think engineers are a bunch of half wits for the way they engineer these cars, most of them do know their perspective jobs. The engineer for that bolt most likely spec a lower grade bolt just for that reason. I have changed my perspective on engineers after my son...

    1972 Dodge Colt

    Slow down the rate of hit on your ClutchTamer. Keep tightening up the the big knob until you only get about a 1000 to 1200 RPM drop at the hit (just at the point the Clutch starts to grab till it is fully engaged) When you get it right the car should knock at least 5 tenths if not more off your...

    2017 ram 2500 broken manifold bolts

    Guys you have to put everything into perspective, there are three different alloys here with three different expansion rates, an aluminum head, cast iron exhaust manifold, and a steel bolt. Something has to give, most times it is the steel bolt that is the weak link( which is believe it or not...

    4500 Series carb has idling problem

    Which Dominator(4500) carb and how new is it? A lot of the newer Dominators have air valves in them around the center were the air cleaner stud is. The valve could be open to far letting too much air to bleed through, in other words a large vacuum leak. On my older Dominator, I had to drill and...

    7 1/4 to 8 3/4 Newb Questions

    Super Cuda, That would tell me that the slip yoke in the end of the trans was sticking out about 3 inches on the original 7 1/4 set up

    7 1/4 to 8 3/4 Newb Questions

    RRR is right, you are going to have to shorten the drive shaft. 7 1/4 10.09 inches from center of ring gear to end of yoke 8 3/4 12.35 inches, that is a 2.26 inches difference in length. So measure the drive shaft that is in the car now and either take 2 to 2 1/4 inches off, with 3/4 to an inch...

    Gen3 hemi tkx swap

    QuickTime use to make the right depth bells for the small block Mopars for the Ford and Chevy input lengths for the Tremec trans. but not any more. I do not think they ever made them for the Gen III Hemis but not sure. For reference the small block Chevy bell for the TKX is 6.29" deep, and...

    Gen3 hemi tkx swap

    Which TKX trans did you purchase? If you purchased the the Ford version, it has a 7.21" input shaft length. The GM one has a 6.71" input shaft length. this is the only two transmissions they make, no Mopar lengths. 833 trans have a 8.5" input shaft length, with a 7.3 bellhousing depth both...

    Hard downshift from 2nd gear to first. A-833 4-speed.

    in your first post you mentioned that you put in a dual diaphragm clutch in the car. Did you mean a dual disk diaphragm clutch? If so check the departure on the second clutch disk(closes to the trans). On sum of these dual disk clutches the disk will hang on the input shaft and keep spinning...

    Tire clearance

    Another wheel tire combo I tried on my Dart were the rear wheels and tires off my 2012 Challenger R/T Classic with the 20x8 inch wide Cragar SS looking wheels with 275/40/20 tires. Those wheels have 5.5 inches of backspacing and the tire are 10.5 inches of section width. Other than I thought the...

    Tire clearance

    Like I said in my other post, a 7 inch wheel with 4.5 inch backspacing(mine were Weld wheels) with a stock A body axle with stock drum brakes. Makes all the difference between a 255/60/15 tire fitting, without rubbing and rubbing on the outside wheel well and lip. I ran those same 255 tires...

    Tire clearance

    My honest opinion is no, I think they will rub on bumps, dips and turns on the outside edge of the wheel opening. I installed the Dr. Diff leaf spring inboard kit (which move the springs in a 1/2 inch and i have Caltrac one inch lowering springs) a few years back and mounted my 9/28/15 M/T...

    Tire clearance

    You need a 7 inch rim with a 4 1/4" (factory bs. on rally and police wheels) or a 4 1/2" backspacing wheel to fit a 255/60/15 tire. The 4 1/2" bs. wheel will give maximum clearance against rubbing with stock to lowered suspension early A bodies with weight in the trunk or 3 to 4 people. I have...

    Front Drum brake troubles on a 1964 Dart

    A buddy of mine went through a similar problem with the 11 inch drum brakes on his GTX. What he found was the same as some others have said, new drums out of round but with a twist. He also found that the new shoes were only touching at the very top of the front shoe and very bottom of the back...

    Cylinder head discussion 340 with stock above deck pistons

    Pittsburgh, Didn't we all run that junk back in the 70's when we didn't know any better, and we broke a lot of parts too. Just like torque converters have come a long way since then, so has clutch technology. I haven't broken a part in my 4spd street Dart in at least 10 years and probably longer...

    Cylinder head discussion 340 with stock above deck pistons

    I am guessing it's been a very long time since you have raced a clutch car. The days of flooring it and dropping the clutch with a 3600 lbs pressure plate are long gone unless you really like destroying driveline parts. It's all about clutch management now.

    Cylinder head discussion 340 with stock above deck pistons

    Not with a stick car with 235 drag radials. He is dropping the clutch at 2500, bogging the engine down and driving out to a 2.0 60 foot. He needs to come out higher and manage the clutch slip with a bias ply slick and get it down to at least a 1.70 60 foot and the car should run in the 12's...

    Cylinder head discussion 340 with stock above deck pistons

    First off is you need to be launching the car at a higher rpm, at least 5000 and ride the clutch out far enough so as to not let the rpm's drop more then a 1000 rpm's. If you have the close ratio 4 spd, then you have a 2.47 first gear coupled with a 3.55 rear gear give you a 8.76 starting...

    1969 Race Dart w/ 426 Hemi- garaged for 45+ years

    You don't want one of those Ansen bells, a buddy of mine had one on his 66 Hemi Coronet and I swear it out weighed the 18 spline 833 that was behind it.

    Adding Bronze Bushings to Ductile Iron Rockers

    Oh ya, and I ran those weakened fragile bushed W2 rockers for 8 years, shifting at 7500 with 670 lbs spring pressure over the nose and thousands of street miles with 4.89 gears. Must have been real lucky, because not one of them broke. They held up better then the Comp roller lifters link bar...

    Adding Bronze Bushings to Ductile Iron Rockers

    It has been quite a few years since I ran W2 heads, so the memory has faded since then. But as far as I can remember from having both a set of bushed and non bushed rockers, there were no differences between them other then the bushing. The part of the rockers the shaft went through were a lot...

    360 stroker questions

    How much power/weight will a stock 833 take? It all depends on the clutch that is going to be used. Add some slip to the clutch and it will last a lot longer than a clutch like a CenterForce II, that will find every weak point from the clutch back. A little clutch slip will improve your 60'...

    How tight to set solid lifters

    rumblefish, I did play with the lash settings with the 590 cam, don't know if it was my combo or or just the 590 cam, but I don't remember it making any difference in the performance of the engine. I do remember that that after playing with the lash settings that I ended up tightening up the...
